| Abstract | As a traditional numerical simulation method for pantograph-catenary interaction research, the pantograph-catenary finite element model cannot be applied to the real-time monitoring of pantograph-catenary contact force, and the computational cost required for the multi-parameter joint optimization of the pantograph-catenary system with the finite element model is very high. In this paper, based on the selective crow search algorithm-radial basis function (SCSA-RBF) network, the time-domain signal of the panhead acceleration, which can be obtained in real-time through non-contact test technology, is taken as the boundary condition to directly solve the pantograph dynamic equation and a data-physics coupling model that can quickly predict the pantograph-catenary interaction is proposed. The prediction model is trained and verified using the dataset generated through the finite element model. Furthermore, the prediction model is applied to the multi-parameter joint optimization of six pantograph dynamic parameters and nine pantograph dynamic parameters, considering nonlinear panhead stiffness, and optimization suggestions under various speeds and filtering frequencies are given. |
