集中质量对接触网仿真的影响研究

电气化铁道弓网动态受流一直是牵引供电系统的关键技术之一.建立高精度的接触网仿真模型,深入研究弓网的动态受流关系,是解决受流质量一个主要途径和方法.在接触网系统中,安装的定位器、定位管、线夹等零部件形成的荷载会影响接触悬挂的弹性,进而对弓网受流产生影响.此文在建立接触网仿真模型中,把零部件荷载视为集中质点,来研究接触悬挂模型的等效质量,进而研究集中质量对接触网仿真的影响.通过研究表明,集中质量的等效质量越大,集中质量处的接触压力越小；反之亦然；列车行驶速度越快,集中质量产生的影响越明显.

Research on the Influence of Lumped Mass on Catenary Simulation

Electrified railway bow net dynamic flow has been one of the key technologies of traction power supply system. Establishing high precision simulation model of catenary and in - depth study of bow net relations of dynamic flow is a main way to solve the current quality. In the catenary system, the load of the locator, locate, clamp and other components will affect the elasticity of the contact suspension, which impact on bow net flow. In the catenary simulation model established in this article, the spare parts load is viewed as a focus point to study the equivalent mass of contact suspension model, and study the influence of the concentrate quality on catenary simulation. Through the study, the larger of the equivalent mass, the smaller the contact pressure, and vice versa. The faster the train speed is, the more obvious the impact caused by concentrate quality is.
