Abstract

Focusing on the optimization design of cam profile in a high voltage switch

parameterized modelling and FEM analysis are performed with the ANSYS in CAE software

and some mechanical parameters

such as transient contact stress distribution are obtained.Based on FEM analysis results

an optimization model of cam is established.Minimizing the maximum contact stress between cam and bearing is selected as the optimization object

and the relevant constraint conditions and design variables are analyzed.Optimization design of cam profile is implemented in the optimization design module of ANSYS

and is compared with the original one.The present method may improve the design quality and efficiency of the cam mechanism in high voltage switch.
