| Effect of wheel/rail wear and suspension system failureon vehicle dynamics performance |
| In order to study the influence of wheel/rail wear on the dynamics performance of the vehicle system, build high-speed vehicle system dynamics model, carry out wheel rail contact geometry relation and dynamic simulation calculation for new wheel/rail, wore wheel/rail and reprofile wheel/rail. In addition, analyze the change of vehicle dynamics performance for wheel-rail relationship after wear, when the parameters of the suspension system are failed. The results indicate that: different profile matching of wheel/rail, on wheel/rail wear condition, equivalent conicity, rolling radius difference and left and right wheel-rail contact angle difference are maximum; instability critical speed decreases due to wheel-rail wear, and riding quality and curve negotiation ability become worse; the influence of wheel-rail wear should be considered in vehicle system simulation; the wheel-rail contact geometry relationship and dynamics performance of the vehicle can be improved effectively by timely wheel reprofiling or rail grinding; the influence of wheel-rail wear should be considered when dynamics performance become worse on fault conditions and vehicle suspension parameters are optimized. |
