Abstract

Abstract

In order to provide a new and efficient method for the selection of vertical suspension parameters of railway passenger car, an extended Ruzicka vibration isolation model of the vertical suspension system was set up, and the harmonic vibration isolation properties of the system were investigated, the optimization method of multiple aims and multiple parameters for the system was carried out by evaluation function method so that the minimum vertical displacement and acceleration of carbody could be obtained. Numerical computation result indicates that the values of optimized result with multi-aim method are much better than the values with single-aim method, the final optimized parameters are related with the optimization aims, and different optimization results are achieved with different optimization aims.
- railway vehicle,
- parameter optimization,
