基于Kriging代理模型的城轨车轮踏面外形优化
Optimization of Urban Rail Wheel Tread Shape Based on Kriging Agent Model
摘要
Abstract
Tread profile is one of the key factors in the vehicle wheel/rail contact system,which directly causes additional loss between the wheel and the rail and affects the dynamic performance of the vehicle.Based on the Kriging agent model,a single-objected scheme and a multi-objected optimization scheme are proposed to cope with the tread profile after the turning of urban rail wheels.By comparing the optimization results with the standard tread,the comparison of the two schemes are analyzed.The results show that multi-objected optimization can fulfill the optimization of multiple objects simultaneously and find a compromise point between multiple optimization targets to improve the overall performance of the system.关键词
