| Popis: | 107 This paper explores the dynamic intermodulation characteristics of the mobile pantograph and trolley line system in the vertical direction. It is assumed that the cantilever set rods and cables in the trolley line system are yello beams, the suspension line and the diagonal suspension line are assumed to be one-way springs, and the stabilizing arm is simulated as a rigid body. The pantograph system is modeled as a three-degree-of-freedom system consisting of three masses, a spring and a damping. The elasticity of the collector boat is modeled as a spring and connected to a virtual mass as a slider that remains in contact with the contact line. In this paper, Newton's second law and finite element method are used to obtain the discretization equations of the pantograph and tram line system, and then combined into the equation of motion of the tram line/collector system. Then, the displacement point of the virtual mass block and the contact line is equalized as a constraint condition, and the multi-body dynamics and the Lagrangian multiplier are combined, and the modified Newmark numerical integration method is used to obtain the trolley line/collection. The dynamic response of the bow system at each moment. |
