Computer Aided Engineering (CAE) FEA Case Study: Conclusions
A pretty successfull FEA outcome - hope it was informative - can we help you with your FEA? 
Stress: Maximum Von Mises stress of around 60-65MPa in tensile areas are acceptable and work well with a maximum stress of 90MPa required for cast LM9 alloy to undergo 2x10^7 cycles. This means the loading can be increased, duty cycle increased or the part optimsied. Further changes could also incorporate different spring rates and bump stops within the suspension etc. The significance of the tyre/wheel interaction is also highlighted and further analysis should be performed on the tyre for a better linear static approximation. Even though FEA should always be more cautious with loads and constraints and overconstrain/overload rather than vice versa.
Displacement:The displacement plot did not add too much information for the wheel, but it did for the tyre, since we know the maximum displacement was in the tyre and spring element. The strains in the wheel were very small but gave the recorded stresses. The tyre's side wall looks too stiff and will change the stresses in the wheel rim.
