I'm working on a final report for the mechanics of material course, and the project was to choose a structure or mechanical element and carry out stress analysis using solidworks and then confirm results with hand calculations. I have chosen a 4-wheel mobile robot structure and worked out the numerical analysis, but confused with the analytical requirements which are:
- The generated six independent stresses.
- The generated six independent strains.
- The generated three principal stresses.
- The generated maximum shear stress.
- The generated equivalent Von-Mises stress.
- The resulting displacement.
I have assumed a load of 500N on the upper surface of the structure and don't know how to start.
The motor shafts are assumed to be fixed in the wheels with bearing support
If you have a resource for a similar problem or you have a clear intuition, I would be grateful to receive your help.
