Abstract:
For the rubber components in bogie suspension of a high-speed train, in order to master the frequency-dependent, amplitude-dependent and temperature-dependent characteristics of nonlinear stiffness and damping coefficient, the high and low temperature characteristic tests of dynamic parameters were conducted. The test method for dynamic characteristic of rubber components parameters was introduced. Both the static and dynamic tests at axial and radial directions were performed for the layer rubber spring mounted on axle box and the rubber joint mounted on the swing-arm. The stiffness and damping coefficient were calculated through the load-deflection hysteresis curve. Test result shows that under the normal ambient temperature of 23 ℃, the stiffness and damping coefficient of rubber components only show frequency-dependent and amplitude-dependent characteristics, but their changes are strongly dependent on the temperature. Compared with the normal ambient temperature of 23 ℃, the stiffness and damping coefficient of the rubber components rise significantly under extremely low temperature environment of -60 ℃. In the case of an excitation displacement of 0.50 mm, the stiffness increases by more than 1 times, and the damping coefficient increases by 4-6 times. The higher the excitation frequency, the greater the increasing rate of stiffness and damping coefficient. In case of high temperature environment of 60 ℃, the stiffness and damping coefficient decrease only 5% and 25%, respectively, with respect to that at 23 ℃. The frequency-dependent and amplitude-dependent of rubber components are nonlinear weakened under high temperature environment. Low temperature causes the change of stiffness and damping coefficient of vehicle suspension system, which in turn affects the vehicle dynamics behaviour. With respect to that at ambient temperature, the running safety index like derailment coefficient increases slightly about 5%, whereas the car body vibration accelerations significantly rise around 17%. 7 tabs, 13 figs, 30 refs.
