Hi,
We try to optimize a monocoque structure for our race car. Therefore we need two loadcases: one for the torsional stiffness and one for the applied suspension loads. To check are model we tested both loadcases separately without any problems. For the suspension loads we used the inertia relief method:
<?xml version="1.0" encoding="UTF-8"?>
we used the PARAM INREL -2 and got reasonable results:
To check the torsional stiffness we need to add the wishbones. We modeled them with PROD's:
<?xml version="1.0" encoding="UTF-8"?>
When we do an analysis with both loadcases we got good results for the torsional stiffness but we got really large compliance for the suspension loads:
Is it possible to implement the inertia relief method on a combination of PCOMPP and PROD structures? Or are there possible other mistakes in our model?
Many thanks,
Jan
