DIY Car Crash Test to Show the Importance of Seat Belt Air Bag

Designer Replica Bags About: I’m a Mechanical engineer who is interested in electronics and other DIY projects. I don’t know much about electronics and I learn by making things. I like to share my ideas with others and I believe that in. Designer Replica Bags

replica handbags online It’s been a while since I have published an article in instructables. Being a Mechanical engineering graduate I always watch car crash test videos by leading car manufactures where things are put replica bags to the limit and thus determining how much safe or how much catastrophic the damage is to the people inside. I always thought about creating a DIY test scenario similar to it but never took that serious and moved with other sort of projects. But 7a replica bags wholesale a week back I though to make this idea practical and give it a try which finally turned into this project. replica handbags online

Fake Designer Bags This project is a buy replica bags online little effort from my side to spread an awareness for car safety. While thinking of car safety, seat belt is the main thing that I’m talking about. This project deals with mimicking different car crash test scenario. The first without seat belt air bag the second one with seat belt and also including the added safety feature called the air bag. It would be better if you could watch the video first. Fake Designer Bags

Replica Bags How often you think about wearing a seat belt when inside a car?? How often you make sure that your kids or your family always buckled up while inside a car?? Are bag replica high quality you that person who ignores seat belt during a short drive?? Replica Bags

Replica Designer Handbags Likewise there are tonnes of other related questions regarding this and it’s a truth that many of us would admit that we are not properly concerned replica bags online about car safety. Replica Designer Handbags

Fake Handbags Studies reveal that from 2011 to 2015, an estimated 343,000 children ages 8 14 were injured while traveling in passenger vehicles, and an additional 1,692 children were killed. A full 50% of those who died were unrestrained at the time of the crash. The numbers seems shocking right?? Then probably it would get worse if we include the death count from age designer replica handbags 8 to 50. If putting a seat belt hardly takes around 10 seconds then why does these accidents happen so?? Can’t people even bare 10 seconds?? I believe that the simple answer is either ignorance or lack of knowledge from the side of people. So I think the solution for this could be creating an awareness and what I’m trying replica designer bags to do is just that. You could either continue reading or ignore this and it’s totally up to you but one thing I could assure you is that if the kids and their parents find some time during weekends to try this project it will be a great experience and may even save their life one day in future. It’s just like the fuel to run the project, as we all know when we mix vinegar with baking soda it causes a reaction, called neutralization which leads to the formation of CO2. This evolving CO2 under a closed vessel could build up pressure and can be used upon need. Actually we are using two types of pressure chamber. The second one, which is comparatively small, is used to inflate the air bag during crash. Let’s best replica bags online start with the bigger one. It consist of a 20 cm long 2 inch PVC pipe where one end is fitted with a 2inch ball valve whereas the other end is fitted with a 2 inch to 1 inch reducer. Then a 1 inch valve followed by 28 cm 1 inch best replica designer bags PVC pipe. The length of the section are take according to my convenience and roughly calculated according to the final setup length and platform where all the fittings are done, which we’ll discuss in the later sections so there is no necessary to strictly follow the dimension. Fake Handbags

KnockOff Handbags The section between the two valves holds the mixture and gets pressurized where the 2 inch valve is used to fill the chamber whereas the 1 inch valve is used to release the pressurized mixture which pushes a specially made piston luxury replica bags arrangement which we will discuss later. Thus it’s clear that the 2 inch valve side is the back side designer replica luggage and the 1 inch valve followed replica designer backpacks by the 28cm long pipe connected to it forms the front side of the chamber. If looked closely it reveals that the mixture should be retained within the two valves and anything that overflow it is of no use. This is the main reason that we are using the 2 inch valve at the back since it is easy to look when the chamber is filled from back whereas in the front looking through the long 1 inch pipe to see the valve filled or not makes it way more difficult. KnockOff Handbags

wholesale replica designer handbags All the parts are well fitted and sealed with PVC solvent to create a strong permanent bond. Simply tight fitting the pipe won’t work for this project since it immediately burst open due to rapid pressure rise. Since we are dealing with this sort of pressure it is very important to use a thicker PVC pipe to be on the safe side. 3mm or 4mm thick at least. wholesale replica designer handbags

Handbags Replica To fill the chamber first closed the front 1 inch valve. Open the back 2 inch valve and place replica bags china it vertically such that the valve faces you. First replica designer bags wholesale fill it up with vinegar and then put the baking soda and quickly close the valve, give it a shake to mix properly. It only takes few second to get the chamber pressurized. One thing to be noted is that fill the chamber up to 3/4 of its capacity and leaves the remaining portion for the CO2 to get filled. So regarding the amount of vinegar and baking soda needed. high end replica bags Since the concentration of vinegar and the quality of baking soda best replica designer varies a lot from place to place it is difficult to specify the exact ratio so better to do some trial and error to get the replica bags buy online best result. What I have followed is 1 teaspoon of baking soda for each 30 ml of vinegar. So it’s under stood that its not literally possible to open the valve at the same time of impact to mimic the effect of air bag. So in order to solve this I used a solenoid valve at one end of the chamber. This chamber is supposed to be kept outside the car (which is not the case in real life scenario) and we use flexible tubes to drive the pressure to the buy replica bags car air bags. This chamber is relatively small which consist of a 1 inch valve at the back followed by a 18cm 1 inch PVC pipe then a 1 inch PVC end cap. Before fixing the end cap some alteration should be made on it. Drill a hole on the end cap such that the solenoid valve inlet port fits tightly in place. Use plumber’s tape at the end of the inlet port of the solenoid valve to create a perfect seal. Please be careful not to confuse between the inlet and outlet port since https://www.thereplicabags.com some valves works properly only in one direction. In most of the cases It will be clearly inscribed on the valve itself. Now the 1 inch valve, pipe and the end cap fitted with the solenoid valve could be fitted permanently with PVC solvent. I also fixed the joints firmly to the end cap using hardening epoxy resin which would also helps further to make a perfect leak proof seal. Here at the back the 1 inch valve could be used to fill the mixture. While the solenoid valve could release the pressure upon giving a power supply. One thing to be noted is that before making the final air bag chamber I have tried it with a water purifier solenoid valve which works on 12v supply. But unfortunately it couldn’t handle the pressure and was not working properly so it left me with no choice that to use a much more pressure rated valve. This creates another problem that most of the higher rated valves are fed from AC mains supply. So I decided to trigger the valve with a signal 9v DC supply through a mechanical relay to the solenoid valve. to make its more safer to work with. Handbags Replica

Wholesale Replica Bags Filling up the chamber Wholesale Replica Bags

Designer Fake Bags Filling the air bag chamber is little bit different from filling the bigger chamber. A main disadvantage while using this technique to inflate the air bag is that the liquid mixture could enter the air bag and creates an undesirable effect during the inflation of air bag. So to drive only the CO2 only small quantity of vinegar is added in the chamber rather best replica bags than filling it up. To be precise I only mixed around 25ml of vinegar with one teaspoon of baking soda. This could make a good pressure CO2 in the chamber which when opened by the solenoid valve leads to a sudden blow of CO2 and then totally stopped. Once it’s inflated and absorbed the impact from the passengers, it quickly deflates for the passengers to escape from vehicle easily. So it will be imperfect if I don’t add this facility to my project. On thinking about it for some time cheap designer bags replica I found that the technique was within the part which I thought of using for this project. The high quality replica bags flexible tube good quality replica bags which I mentioned earlier, was supposed to carry this pressurized air to the air bag. This flexible tubing was actually used with water purifier. Since we can’t use a single closed pipe to run the full length due to the complexity in running the pipe inside the car I used joints in between. On a close examination of each joints I found that around its periphery it consist of a special locking mechanism for the high replica bags tube. This mechanism provides a small clearance between the joint and the connected pipe which could depressurize the air bag before inflation. but lots of clearance could let replica bags from china the pressure escapes first through these clearances. So I sealed every clearence but left one intact, It is explained in detail in the air bag tubing sectionStep 4: Air Bag Tubing Arrangement Designer Fake Bags

Replica Handbags The tubes and fitting (joints) are actually used in water purifiers but it works fine in our arrangement. The tubes are around 2.5mm in diameter and could be bought from a nearby water purifier store. In order to achieve the correct shape to match with the profile of the car several pieces of pipe are heated and bended to achieve the required dimensions. While heating make sure that you insert an electrical wire which fits perfectly inside the tube before heating. This helps to maintain the internal dimensions unchanged while Appling stresses on the tube. replica wallets Another thing to be noted is that I have mentioned about sealing the pipe joints perfectly but never explained how. Here it is I use this technique a lot in my experiments if air tight is a necessity. So first expose the place which is to be sealed. Since from the pack which I bought a small cap like structure was there aaa replica bags and can be inserted in the joining section. This helps in holding the tubes firmly. I believe this is common for any water purifier tubing fittings. Ok back to sealing, after exposing the section put some talc powder on the seal and gently press it and compact it. After doing it apply some super glue on it and leave it for 5 minutes to perfectly harden. The result is a perfect seal without any leakage. The tube layout is as follows Replica Handbags.
