Effects of Contact Strips Wear on Service Performance of Pantograph System

摘要

摘要: 为了实现滑板磨耗形面的描述和它对受电弓服役性能影响的评估，研究了滑板磨耗对弓网系统动力学性能、受电弓抗疲劳性能的影响.首先，通过对比分析大量受电弓滑板实测形面数据，提出以二次函数描述滑板磨耗形面，给出形面形状参数和磨耗深度参数两个特征量，并获得了特征量随运行时间的变化规律；其次，采用模态叠加法建立了考虑滑板形面的弓网耦合动力学模型，探讨滑板磨耗对弓网动态受流性能的影响；最后，根据滑板磨耗形面具有明显的时变性的特点，建立了考虑参数时变的受电弓疲劳寿命预测模型，实现滑板磨耗形面对受电弓抗疲劳性能的影响分析.研究结果表明：滑板形面磨耗增强了弓网系统的跨距周期性，导致该特征主频的幅值增加，且滑板形面的形状参数绝对值越大，弓网动态性能越差；考虑滑板形面磨耗后，受电弓框架部件的预测疲劳寿命缩短，缩短量约为30%~40%，且越处于上端的结构影响越大.

Abstract: To realize the parametric description of contact strips wear surface and evaluate the influence of contact strips wear on the service performance of pantograph systems, the effects of contact strips wear on the dynamic and fatigue performance on the pantograph-catenary system were investigated.. Firstly, based on a large amount of measured data of contact strips surface, the quadratic equation was proposed to fit the contact strips surface. Two characteristic quantities were defined, i.e., the surface shape parameter and wear depth, and the rule of characteristic quantities varying with time was obtained. Secondly, the mode superposition method was adopted to build a dynamic pantograph-catenary coupled system model, which takes into account the wear characteristics of contact strips. Based on the model, the effects of contact strips wear on the current collection performance of the coupled system were explored. Finally, a fatigue life prediction model considering the time-varying characteristics of contact strips surface wear was built. The effects of the wear on the fatigue performance of pantograph were analyzed. Results indicate that the wear surface of contact strips enhanced the periodic frequency with wave length of span increasing the amplitude of the dominant frequency. The larger the absolute value of surface shape parameter, the poorer the dynamic performance of the pantograph-catenary coupled system. When considering the contact strips surface wear, the predicted fatigue life of pantograph frame parts was reduced by about 30%-40%, and the upper structure was affected more greatly.
