Optimal design method for brake supporting structure

Abstract

The invention discloses an optimal design method for brake supporting structures of various vehicles, and aims at brakes of various vehicles. A topological optimization design method taking a geometric topological structure of a supporting structure as a design variable and a shape and size optimization design method taking a structure size parameter as a design variable are combined. According tothe method, multi-disciplinary and multi-objective optimization design can be carried out on brake supporting structure performance evaluation standards including but not limited to flexibility, displacement, thermal flexibility, volume, stress and the like under reasonable objective functions and constraint conditions. And structural features are extracted based on a topological optimization result to perform parametric modeling of the supporting structure, shape and size parameter optimization design is performed on the structural features under the parametric model, and parameter optimization design is further performed on the brake supporting structure. According to the brake supporting structure obtained through the method, smaller deformation can be obtained under the condition thatmore sizes are reduced.
