摘要:
为了研究抗蛇行减振器油液温度对其动态特性和车辆稳定性的影响以及抗蛇行减振器服役过程中的温变特性,对我国某高速动车抗蛇行减振器进行了试验和动力学仿真分析。试验结果表明,在油液正常工作温度范围内,减振器吸收的能量、动态阻尼及动态刚度随油液温度的降低而增加;而当油液温度超出抗蛇行减振器油液正常工作范围时,减振器吸收的能量、动态阻尼及动态刚度随油液温度降低而降低。减振器在非正常工作温度范围内服役,2 h 内温度和动态特性变化不明显,且减振器没有恢复到正常工作。仿真结果也表明,在油液正常工作温度范围内,蛇行临界速度随油液温度的降低而增大,而当油液温度超出油液正常工作温度范围时,蛇行临界速度随温度降低而降低。
Abstract:
The field test and simulation analysis were accomplished to analyze the impact of oil temperature on inherent dynamic performance of yaw damper and vehicle stability and temperature characteristic of yaw damper. The test results showed that the absorbed energy by yaw damper, the dynamic damping and stiffness of damper increased with the temperature decreasing in the proper range of oil temperature, while decreased with the temperature decreasing when it exceeded the proper range of oil temperature; The temperature and dynamic feature had no obvious change and yaw damper could not recover normal state within two hours as yaw damper’s oil temperature was not at the range of normal working temperature. The simulation results also showed that the critical hunting speed increased with the temperature decreasing in the proper range of oil temperature, while decreased with the temperature decreasing when it exceeded the proper range of oil temperature.
