拓扑优化与尺寸优化相结合的割草车车架轻量化设计
The Light-weight Design of the Cutting Grass Car Frame Combined the Topology Optimization with the Size Optimization
摘要
Abstract
The frame lightweight is an important way of energy saving and cost reduction.This paper based on a frame of a cutting grass car,puts forward a design method combined the topology optimization with the size optimization for the lightweight of cutting grass car frame.On the premise of meeting the working performance and the strength of frame,this paper uses the finite element simulation technology to go on the strength analysis under the bending condition and torsion condition. On the basis of the analysis results,it continues the secondary optimization combined the topology optimization with the size optimization.Then it makes a comparison on the results of the strengthanalysis on the frame before and after optimization.The results show that the final optimization result meets the requirements,and the weight loss percentage is up to 34.3%.it is obvious that the effect of lightweight is remarkable.关键词
