摘要

本文讨论了多体动力系统的最优设计问题(平稳最优控制)。该系统包括与梁桥相互作用的列车和轨道上部结构。据估计，火车的速度可以达到每小时400公里。研究了连续子系统轨床的最优刚度分布问题。优化的目的是在最小的轮轨垂直接触力约束下减小轨床载荷的不均匀性，防止脱轨。

The stationary optimal control in combined discrete and continuous system

The paper discusses the problem of optimal design (stationary optimal control) for multi body dynamic system. The system includes a train and track superstructure interacting with a beam bridge. It is regarded that the speed of the train can reach 400 km/h. The problem of optimal stiffness distribution for continual subsystem – rail bed – is considered. The aim of the optimization is decreasing of irregularity of rail bed loading under constraint on minimal vertical wheel-rail contact force that prevents derailment.
