摘要:
建立了包含锚段关节的门式悬挂结构刚性接触网有限元模型,并将受电弓等效为集中质量块模型;利用罚函数实现弓网接触,通过Newmark数值积分来求解弓网耦合系统动力学方程组。依据铁路标准验证了有限元模型的有效性。通过有限元模型仿真,研究了受电弓结构参数,以及刚性接触网跨距、悬挂结构刚度、静态抬升力与锚段关节对弓网动态性能的影响。仿真结果表明,刚性接触网跨距、悬挂结构刚度及锚段关节对弓网受流质量影响显著。

A finite element model of rigid catenary considering overlap is developed. Pantograph is translated into lumped mass model and penalty function is utilized to describe the contact between them. Newmark numerical integration is used to solve the dynamics equations of the pantograph coupling system. The validity of the finite element model is verified according to railway standards. Through finite element model simulation, pantograph structure parameters are studied, as well as the influence of rigid catenary span length, suspension structure stiffness, lifting force and overlap on pantograph dynamic performance. Simulation results show that the rigid catenary span length, suspension structure stiffness and overlap have significant impacts on the pantograph current collection quality.
