- Abstract
Based on multi-body system dynamics, the model of Yutong high-speed bus was built by ADAMS/Car software to analyse the influence of crosswind on the high-speed bus' handing stability. Seven discrete wind pressure centers effects on the chasis were taken into account, so the crosswind model with a shifting pressure center was achieved. After improving the standard of the crosswind sensitivity test that is prescribed by American ESV (Experimental safety vehicle), the crosswind simulation tests with pressure center's shift and the immobile pressure center were carried out. The high-speed straight-line simulation test without the crosswind was also completed. By comparing the results of the three tests, the test data in consideration of wind pressure center's shift was more reasonable and provided the reference data for improving the crosswind stability of the bus.
