高速列车动力学性能参数优化迭代设计
Iterative Optimization Design for Dynamic Performance Parameters of High-Speed Trains
摘要
Abstract
To optimize the dynamic performance parameters of high-speed trains,an iterative design framework for dynamic performance optimization of high-speed trains was established.First,dynamic design parameters were extracted,and a dynamic performance analysis model was constructed.Next,the design space was reduced through importance analysis of the design parameters combined with self-organizing mapping,and an experimental dataset of performance parameters was generated through multidisciplinary coupled simulation.Finally,a multi-objective optimization model was established under multiple working conditions.Based on Bayesian optimization and random forest,a surrogate model for multiple working conditions was developed.An improved non-dominated sorting genetic algorithm Ⅱ(NSGA-Ⅱ)was employed to identify a set of optimal design parameters.Following optimization,the experiment conducted under a representative working condition demonstrates performance improvements of 1.14%,3.19%,2.86%,2.30%,8.33%,2.77%,and 8.11%in lateral ride comfort,vertical ride comfort,vertical wheel-rail force,lateral wheelset force,derailment coefficient,wheel load reduction ratio,and overturning coefficient,respectively.These findings validate the feasibility and effectiveness of the proposed iterative design method,providing references for the forward innovative design of complex equipment.关键词
