创建新的受电弓设计时出现的问题之一与为煤插入和悬链线磨损最小化而选择的几何参数有关。为了确定受电弓与导线接触处的动载荷，利用MSC.ADAMS软件进行了仿真分析。根据计算，获得受电弓和导线连接情况下的接触力-时间依赖性。模拟结果随后用于分析煤嵌件的应力应变状态。受电弓-接触网导线接触相互作用的有限元建模在ANSYS中进行。创建的模型包括金属丝、煤炭嵌件和钢衬里的部分。考虑到结构的对称性，创建了真实结构的半模型。模型有限元总数等于 401 717。纵向和垂直力施加到线零件端点。这些力对应于受电弓和接触线之间的相互作用力。计算结果表明，等效应力最高值出现在衬砌角部，对于矩形截面的情况，存在石墨碎裂现象。
One of the problems appearing at creating of new pantographs designs is associated with the geometric parameters selection for the minimum wear of the coal insertion and the catenary wire. To determine the dynamic loads in the contact between the pantograph and the wire, there was performed the simulation analysis using MSC.ADAMS software. According to the computations the contact force-time dependence for the case of connected pantograph and wire was obtained. The simulation results were later used to analyze the stress-strain state of the coal insert. The finite element modeling of the pantograph-catenary wire contact interaction was performed in ANSYS. The created model included parts of wire, coal insert and steel lining. Taking into account the symmetry of the construction it was created the half-model of real construction. The total number of model finite elements was equal to 401 717. Longitudinal and vertical forces were applied to the wire part end points. These forces correspond to the interaction forces between the pantograph and a contact wire. The computational results demonstrate that the highest values of equivalent stresses appear at the lining corners, and, if for the case of the rectangular cross-section there is a phenomenon of graphite crumbling.
