I have experience of heavy commercial vehicle suspensions, including FE Analysis of these components. Although I have used ANSYS in the past, my proposal would be to do this analysis on SolidWorks Simulation (i.e. COSMOS).
I propose to solve the needed stress analysis problem on your truck axle using Solidworks FEA software. I am professional engineering designer based in the USA. I have previously done similar analyses for BMW and Michelin. My bid is to complete the project in 3 days at a cost of $275. Thank you in advance for your business.
