An Optimal Design Method for Brake Support Structure

Abstract

The invention discloses an optimal design method for various vehicle brake support structures. The proposed method is aimed at brakes for various vehicles and combines the topology optimization design method with the geometric topological configuration of the support structure as the design variable and the A shape and size optimization design method with structural size parameters as design variables. This method can perform multidisciplinary and multi-objective optimization design on the performance evaluation criteria of the brake support structure, including but not limited to compliance, displacement, thermal compliance, volume, stress, etc., under reasonable objective functions and constraints. Based on the topology optimization results, the structural features are extracted for parametric modeling of the supporting structure, and the structural features under the parametric model are optimized for shape and size parameters, and the parameter optimized design for the brake supporting structure is further carried out. The brake supporting structure obtained by adopting the present invention can obtain smaller deformation while reducing a lot of volume.
