optimization of automobile suspension component
optimization of automobile suspension component
(OP)
Hello Everyone !
I am doing project on " Optimization of suspension component"(Mcpherson Strut Lower Link). In that I have to reduce the 'weight' of the link keeping it's strength and stress distribution same . I want to know more about .....
1. How to find the areas from which the material can be removed??? Is there any specific method for that. ??? Please note here that stress distribution should not be changed drastically. What properties of the component we have to consider for that ??
2. What is load path . How do we find that in statically indeterminate structures ??? How can we use load path to find the areas for weight reduction .
3. Is there any FEM based method for this ???
Regards
Kedar.

2) FEM
3) Yes
part of the trick is defining your loads for the optimisation. As a minimum you should determine the stresses in response to 3 g vertically 2g longitudinally and 1 g laterally (times the corner mass, or 1/4 vehicle mass) and consider the effect of mixtures of those loads.
In practice the fore-aft and lateral loads will probably be the most significant.
I imagine that most modern FE packages have an optimiser built in, whether it is any good is another issue.

If you are refering to typical, simple lower lateral links (2 pt. pickup each), then it is primarily a column buckling analysis.
If it is an arm arangement (3 pt. pickup) then a FEA analysis is probably your best bet.

I have one doubt relating to earlier question .
1. In statically inderminate structures , does maximum stress and
maximum strain energy locations same or different. ????
2. How to find strain energy locations in a component using I-DEAS 8.0 and MSC/NASTRAN. ???
Thanks all in advance
