摘要
首先建立了弓网动力学模型。在其余参数均不变的基础上,研究了承力索张力对弓网受流质量的影响,并对各个工况进行了仿真。仿真结果表明,增大承力索张力可以减小弹性不均匀系数,增大反射系数,且接触压力与振幅呈不规则变化趋势。最后提出了几个相应的建议。
In this paper, we set up a dynamic model on Pantograph-Catenary System. Based on other parameters being hold, The influences of Current-receiving quality between pantograph and OCS from Tensile force acting on catenary wire are studied. We further simulated each project. The Result analysis indicates that increasing Tensile force on catenary wire will reduce Non-uniformity of elasticity and improve Reflection factor. However , the Contact force and amplitude change are irregular. Finally, some corresponding advices are put forward based on the above experiments.
