Study on dynamic contact force of pantograph catenary system
摘要
Abstract
In order to obtain the change rule and achieve optimal control of dynamic contact force in pantograph-catenary system,lots of contact force experiments were carried out.The statistical characteristics of contact force were analyzed by using mathematical statistics method.The dynamic contact force is periodic fluctuation and it is in accord with normal distribution.The dynamic contact force fluctuates between average contact force add three times the standard deviation and average contact force subtract three times the standard deviation.The fluctuation range increases with the increase of running speed.The vibration frequency of pantograph-catenary system depends on running speed and static contact force.关键词
