随着高速列车运行速度的提升,弓网关系这一基础力学问题备受关注.良好的弓网关系是确保列车安全高效运行、稳定可靠受流、降低接触线与受电弓滑板磨耗等的基本前提.其中,受电弓和接触网的动力学参数对弓网耦合作用起至关重要的作用.本文采用弓网接触力随机统计特征作为优化目标函数,进行受电弓动力学参数的敏度分析和优化设计.首先,建立了二维弹性链悬挂接触网-三质量块受电弓动力学模型,根据EN50318:2018标准验证了动力学建模和分析结果的正确性.然后,基于高速弓网系统的动力学仿真,进行了DSA380型高速受电弓三质量块参数的动力学敏度分析,确定了9个动力学参数的敏感度级别,弓头等效质量敏度评级最高,下框架等效阻尼次之,下框架等效质量和上框架等效阻尼第三.最后,研究了弓头等效刚度和等效阻尼联合变化对弓网耦合动力学性能的影响,给出了提升弓网耦合性能的弓头双参数优化方案,建议同时减小弓头等效阻尼和增大弓头等效刚度,能够实现比单参数优化更好的弓网耦合性能. |

With the improvement in the speed of high-speed trains,the dynamic interaction between pantograph and catenary,a basic mechanical problem,has attracted more attention.Good pantograph-catenary relationship is a basic premise to ensure the security and efficiency of the train operation,the stability and reliability of the current collection and reduce the wear of the contact line and pantograph slide.The coupling performance of the pantograph-catenary system mainly depends on its kinetic parameter.In this paper,the stochastic statistical characteristics of the contact force of the pantograph-catenary system are adopted as the optimization objective function,and the sensitivity analysis and optimization design of pantograph dynamic parameters are carried out.Firstly,a dynamic model of 2D stitched catenary and three lumped parameter pantograph is established,and the validation of dynamic analysis of the model is verified according to British Standard EN50318:2018.Secondly,based on dynamic simulation of the high-speed pantograph-catenary system,a dynamic sensitivity analysis on three lumped nine dynamic parameters of DSA380 high-speed pantograph is carried out,and the sensitivity level of the parameters is determined.The sensitivity level of the equivalent mass of the pantograph head is the highest,followed by the equivalent damping of the lower frame and the equivalent mass of lower frame and the equivalent damping of the upper frame are the third.Finally,the effect of joint variation in equivalent stiffness and equivalent damping of the pantograph head on the pantograph-catenary coupling dynamic performance is studied,and a dual-parameter optimization scheme of equivalent stiffness and equivalent damping of the pantograph head is proposed to improve the current collection quality pantograph-catenary system.It is suggested to reduce the equivalent damping of pantograph head and increase the equivalent stiffness of pantograph head at the same time,and the dual-parameter optimization scheme can achieve a better quality of the pantograph-catenary system than the single parameter optimization scheme. |
