Creo Simulate Random Dynamic Analysis Stress Values
Our company has a reliability lab that utilizes a shaker table to do vibration testing on our products prior to full production. We had an aluminum bracket that failed, and after failure it was redesigned, and passed. I wanted to use Simulate to see if there was a way to consistently test other parts/assemblies prior to vibration testing to give us a better idea if they would pass or fail. The tensile yield strength of 5052 aluminum is 193 MPA, so I was expecting the failed part to be above that, and the part that passed, below that. However, after getting the assembly set up, and running the analysis the numbers I'm getting are in the 100s of thousands, showing basically that the entire part would fail. I've been working with PTC tech support as well, and they're not having any luck figuring out what is going on either.
We are trying to use the data that we received from our reliability lab as far as the input for the vibration. The parts are tested in 3 different orientations. These values can be seen below.
