So I'm trying to perform a basic crash test in SolidWorks of a model I have created. But first, I'm trying to figure out how to exactly perform a crash test! From what I've read online, impact tests are normally done in nonlinear dynamic studies. My long term goal is to extrapolate what I learn here to a larger, more complex model for impact testing. Here is what I have so far:
Right now, I'm more concerned with just getting the basics of crash simulation down, so I've chosen a very simplistic model to learn from. The large wall is fixed, and there is an initial condition of 20m/s set on the smaller cube in the direction of the wall. There is a no penetration contact set between the wall and the cubes front faces, and a global contact between the two parts (I've tried running it with Global contact off, when I did I received the error "no initial contact is detected"). Currently when I try to run the simulation, I get some pretty weird results, indicating to me I've obviously done something horribly wrong. I've also tried looking up YouTube videos and help guides on impact simulations, but unfortunately it doesn't look like there is a whole lot to learn from. This is the best example of what I'm trying to do I have found so far:
From his simulation, I know its possible to perform an impact test, I just can't figure out for the life of me what I am doing wrong!! Anyways, If anybody is willing to give me any information they have on performing an impact test using nonlinear dynamic simulation, I would love to hear it. Also, for anybody who wants to take a look at the assembly:
Thank you for your time.
