In Static Structural analysis of the roll cage, I am getting a FOS of around 1.5 by using static loading conditions of 10G on the roll cage.<\/p>\n<p>In the dynamic analysis, I am getting a very low FOS of around 0.2. I have tried adding structural support, increasing weldment thickness, and other such things without obtaining a significant change in FOS.<\/p>\n<p>Have I done some common mistakes or errors?<\/p>\n<p>I have done 2D surface meshing by the way.<\/p>\n<p>Thanks in advance for any suggestions or help related to troubleshooting the issue.
