Abstract

The invention discloses a topological optimization method for improving the modality of an automobile air conditioner compressor support. The method comprises the steps: constructing a three-dimensional assembly model of a compressor system, a compressor support and a power assembly, and carrying out the structure dispersion and grid division of the three-dimensional assembly model; constructing and dividing a design area and a non-design area of the compressor bracket; by taking the relative density of the unit as a topological design variable, adopting an SIMP algorithm to carry out topological optimization on the design area of the compressor bracket; applying boundary conditions, and acquiring the optimization variables, constraints and optimization targets; by using a relative density topological optimization algorithm, performing multiple iterative calculations to acquire a compressor support after topological optimization; and correcting the compressor bracket after topological optimization, and obtaining a three-dimensional model of the optimized compressor bracket. By means of the scheme, the method has the advantages of being simple in logic, reliable in optimization and the like, and has high practical value and popularization value in the technical field of automobile air conditioner compressor support optimization.

Description

technical field [0001] The invention relates to the technical field of optimization of automobile air-conditioning compressor brackets, in particular to a topology optimization method for improving the mode of automobile air-conditioning compressor brackets. Background technique [0002] Automobile air-conditioning compressor is the heart of automobile air-conditioning refrigeration system, which plays the role of compressing and transporting refrigerant vapor. Among them, the compressor and the engine tend to form resonance at a certain speed, and the noise generated will make the members feel uncomfortable. Among them, the bracket is an important aspect to solve the vibration transmission of the compressor.
