弓网动态接触压力测量方法研究

Research on the Measurement Method of Pantograph-Catenary Dynamic Contant Force

在电气化铁路中,弓网接触压力对机车供电可靠性及质量起着重要作用。通过总结分析国内外测量方法,对影响弓网接触压力的因素及受电弓受力情况进行分析,设计一种检测弓网动态接触压力及机车运行方向摩擦力的装置,并对误差进行分析。

On electrified railway, the contact force between the catenary and pantograph plays an important role in the locomotive power supply reliability and quality. After summarizing the domestic and foreign measurement methods, the authors analyze the factors influencing pantograph-catenary contact pressure and also analyze the stress burden on pantograph. The authors design a device to detect the pantograph-catenary dynamic contact pressure and the friction force along the running direction of locomotive. The errors are an^lw^rl ~,1~,-,
