Problems solved by technology

[0002] At present, the brake discs commonly used in vehicles are cast iron or forged steel brake discs, whose materials have high density, poor thermal conductivity, and are prone to thermal damage
Aluminum matrix composites have the characteristics of small thermal expansion coefficient, low density, high temperature resistance, and wear resistance. In recent years, a lot of research has been done on the processing of aluminum matrix composites at home and abroad. The simulation of the disc temperature field is still in the initial research stage, and there is no specific method for the temperature field matrix, which makes it impossible for the R&D personnel to effectively analyze the designed brake disc during the R&D process

Abstract

The invention discloses a temperature field simulation method and device for a composite material automobile brake disc, and the method comprises the steps: importing a geometric model of the brake disc, and setting the material parameters of the geometric model based on the attributes of a composite material of the brake disc; determining analysis steps of the geometric model, and setting a boundary condition and an initial condition for each analysis step; and simulating and calculating a temperature field cloud picture corresponding to the geometric model based on the analysis step. According to the method, after the material parameters of the constructed geometric model are set according to the attributes of the composite material of the brake disc, simulation calculation of the temperature field nephogram is carried out on the geometric model, when the simulation result is not ideal, material design optimization can be carried out on parts only by adjusting the material parameters, and the design cost is reduced.
