Based on SIMPACK to Reduce the Proportion of Test Vehicle Modeling Analysis

Abstract

In order to solve the problem of the railway line in service is difficult to carry out the real vehicle experiment, a reduced-scale experiment system for vibration was proposed according to the similarity theory and SIMPACK dynamic model analysis. In this paper, two SIMPACK dynamic model were built. Among them, one model is the real vehicle SIMPACK dynamic model, and the other is the test vehicle SIMPACK dynamic model. By using the dichotomy to adjust the test vehicle’s primary suspension and secondary suspension parameters, so that the real vehicle model and the test vehicle model are output the same parameters when running under the same conditions. Experimental results shows that the output parameters of the test vehicle model are basically consistent with the output parameters of the real vehicle model. Test vehicle can be a good simulation of the actual situation, the reduced-scale experiment system for vibration is feasible.
