Study on Pantograph-catenary Current Collection Characteristics of Rigid-flexible Transition System Scheme for OCS of 120 km/h

刚柔过渡区段是接触网系统的重要组成部分,其结构复杂,是影响弓网受流性能的关键区段,为此需要开展时速120 km刚柔过渡系统方案研究,为项目实施提供理论支撑。本文以有限元理论为基础,建立刚柔过渡仿真模型,通过弓网动力学计算,对120 km/h刚性接触网不同刚柔过渡系统方案进行分析和优化。

Rigid-flexible transition is an important part of overhead contact line system with complex structure and isthekey section that affects the flow performance of the between pantograph and overhead contact line.Therefore,it is necessary to study the scheme of rigid-flexible transition system with 120 km/h to provide theoretical support for engineering implementation.In this paper,a rigid-flexible transition simulation model and a pantograph simulation model are established based on the finite element theory,and different rigid-flexible transition system schemes of 120 km/h are analyzed and optimized through the dynamic calculation of the between pantograph and overhead contact line.
