Abstract

The invention relates to a mechanical equipment structure optimization design method and system, and the method comprises the steps: building a finite element model of mechanical equipment under different working condition loads, and determining a plurality of key design variables of the mechanical equipment through the simulation analysis of the finite element model; sampling the plurality of key design variables, and inputting sampling points into the finite element model to obtain a response value corresponding to each sampling point so as to construct a simulation approximation model and perform model precision evaluation; establishing a structure optimization model of the mechanical equipment based on the simulation approximation model meeting the model precision requirement; and performing global search on the structure optimization model through an improved simulated annealing particle swarm algorithm to determine an optimal value of the key design variable. According to the method, the optimized structural design of the mechanical equipment can be efficiently completed, and the structural design accuracy of the mechanical equipment is improved.

Description

technical field [0001] The present application relates to the technical field of mechanical equipment design, in particular to a method and system for structural optimization design of mechanical equipment. Background technique [0002] With the steady development of the domestic economy, machinery and equipment such as automobiles, high-speed rail, aircraft, ships, and construction machinery have developed rapidly. Taking automobiles as an example, the number of domestic automobiles will reach 281 million in 2020, accounting for 75.5% of the national motor vehicle population. Mechanical equipment places very high demands on weight and safety. The overall structure of mechanical equipment is bulky, which will lead to a substantial increase in material and operating energy consumption, which is not conducive to energy saving and emission reduction. In addition, the structure of mechanical equipment generally carries a large load and the use environment is complex, and unreas...
