Automotive Clutch Principal Components Analysis And Topology Optimization

According to the strength theories of the material, any objects will take place to split when the stress value of the material attains the stress or the yielded extreme limit. Therefore we must carry on the comprehensive considerations at the time of designing the clutch, and make sure that the stress value should not exceed the extreme limit.This paper mainly made use of the analysis software ANSYS to build up the FEA models of four parts of the clutch, and used the analytical function of ANSYS to calculate the quiet stress under the most dangerous work condition to get their most quiet stress and strain,and also analysised their intrinsic mode to get their proper frequency. After that carried on the experiment of some spare parts to certificate that the result of the software calculation is right.Then setting out from the curve of S-N of the material, and according to their tired characteristic,made use of the strong fatigue analysis software MSC.Fatigue to calculate their lives.Then in order to validate the use of FEA analysis software dependable, we used the experience calculation formulas of tired design to carry on the tired calculation.This paper illustrated the whole flow of the topological optimization with some parts of the cluch at last, and carried on to re-design on this foundation providing the reference for the later design.
