    Impact attenuator test

    Hi everyone, when testing the Impact Attenuator, welded or glued to the anti intrusion plate, should it be connected to a solid body that looks the same as the front bulkhead, and made from the same material? Or just another solid body 2 inches beyond the ant intrusion plate.
    Thanks.

    It is just simple courtesy to introduce your self. This is not a supermarket....

    We've done it just like the front bulkhead. When testing anything you always have to be aware of how your test setup could make your results totally useless when applied to the real situation. For sure the RC will like it when they review your IA report and it's close to reality. Maybe use it as welding practice!

    But when using monocoque it's not so simple...

    That's because building with a monocoque is not so simple! One of the things you have to think about if making the switch.

    Obviously you have to mount the IA and the Anti intrusion plate to something shaped like your front bulkhead and use the mounting method you are planning to use at your car. Otherwise the test doesn't make any sense as it won't tell, if the IAP is able to withstand the forces without deflecting to much.
    How is that not simple if you are planning to build a monocoque? You only need a piece which is shaped like your front bulkhead which you bolt the IA and the anti intrusion plate to. Sorry, if this sounds rude, but if you want to build a monocoque and consider this a difficult task, you are already in deep trouble. If you have a solution and are not sure if it is correct, just ask the rules committee of the competition you take part in, if it is ok. (I won't tell you how to do it, other teams had to figure it out by themselves, too.)

    Document everything properly and remember that the whole assembly has to be presented during tech inspection so the scruntineers can check if it is comparable to the setup of your car.
