受电弓-架空刚性接触网弓网系统动态性能的优劣对于列车安全运行产生重要影响,掌握刚性接触网弓网系统动态性能的有效途径之一是建立弓网动态仿真模型进行仿真分析。为保证弓网动态仿真计算的有效性和适用性,有必要开发受电弓-架空刚性接触网弓网系统动态仿真平台。本文根据工程实际应用,基于铁木辛柯梁理论与有限元理论建立刚性接触网弓网耦合动态仿真模型,开发受电弓-架空刚性接触网弓网系统动态仿真平台,与弓网在线实测数据进行对比验证其有效性与准确性,为刚性接触网设计及运维提供技术支撑。

The dynamic performance of pantograph and rigid OCS has an important impact on the safe operation of trains.One of the effective ways to grasp the dynamic performance of rigid OCS is to establish a dynamic simulation model for simulation analysis.In order to ensure the effectiveness and applicability of the dynamic simulation calculation of the OCS,it is necessary to develop dynamic simulation platform for pantograph and rigid OCS.The paper,on the basis of the practical application of engineering,a dynamic simulation model of rigid OCS coupling is established based on the theory of the Timoshenko beam and the finite element theory,and dynamic simulation platform of pantograph and rigid OCS is developed to verify its effectiveness and accuracy by comparing with the online measured data,providing technical support for the design,operation and maintenance of rigid OCS.
