| titleOfInvention | Evaluation method for seismic performance of subgrade trains based on three-dimensional wheel-rail contact |
| abstract | The invention provides a method for evaluating the seismic performance of roadbed trains based on three-dimensional wheel-rail contact, which includes the following steps: establishing a three-dimensional finite element model of roadbed trains according to design geometric parameters and material parameters; introducing soil into the three-dimensional finite element model of roadbed trains The initial stress state of the model is obtained by calculating the initial stress of the body structure in the initial working condition; after adding external load conditions to the 3D finite element model of the roadbed train in the initial state, the seismic response of the roadbed train is calculated; using the obtained wheel-rail dynamic earthquake Response to evaluate the seismic performance of subgrade trains. The invention solves the problem of seismic performance evaluation in the design process of subgrade trains, and the method is simple and easy to implement, deepens the understanding of train track coupling and soil layer stress distribution, improves design efficiency, and reduces test randomness and capital investment , providing a powerful theoretical basis and scientific guidance for more accurate and efficient optimal design of subgrade train systems. |
