利用动态子结构系统和MDOF接触网模型对受电弓/接触网系统进行混合仿真测试

Hybrid Simulation Testing of a Pantograph-Catenary System Using a Dynamically Substructured System Framework and a MDOF Catenary Model

本文基于动态子结构系统(DSS),提出一种受电弓/接触网系统混合仿真(HS)法。与逆传递函数法等常用方法相比,DSS能够更好地避免作动器动力学不稳定性,能更精确地描述受电弓与接触网之间的动力学响应。

This paper proposes a hybrid simulation(HS)method for pantograph/catenary systems based on a dynamically substructured system(DSS).Compared with commonly-used methods such as the inverse transfer function approach,DSS is better able to avoid instability in the actuator dynamics,and is also able to accurately represent dynamic interaction between the pantograph and the catenary.
