车辆-道岔系统横向振动特性研究

Study on lateral dynamic characteristics of vehicle turnout system

就 1 2号可动心轨式单开提速道岔 ,建立了较为详细的车辆 -道岔空间耦合振动模型 ,在此基础上模拟计算了客、货车侧向过岔时车辆与道岔系统的横向振动特性。结果表明 ,车辆侧向过岔将引起整个系统在横向上发生比较大的振动 。

Aimed at the No.12 speed raised single way turnout, a comprehensive coupling dynamical model of the vehicle/turnout system has been established in this paper. Based on the model,the lateral dynamical characteristics of the vehicle/turnout systems have been simulated. It's shown that the intensive lateral vibration of the systems will emerge while the vehicle passing through the turnout, especially at the switch and frog area of the turnout zone.
