【摘要】 通过试验，系统性分析了某型橡胶球铰径向压缩刚度变化趋势。结果表明，橡胶球铰径向压缩刚度随着试验时间的延长呈现逐渐变小的趋势；随着试验次数和恒温时间的增大慢慢趋于稳定；橡胶层厚度对球铰径向压缩刚度变化趋势的影响不大。更多还原

【Abstract】 Through experiments, the radial compressive stiffness variation of a certain type of rubber ball bush was systematically analyzed.The results showed that the radial compressive stiffness of the rubber ball bush gradually decreased with the extension of the test time.It gradually stabilized with the increase of the number of tests and the time at constant temperature.The thickness of the rubber layer had little effect on the radial compression stiffness variation of the ball bush.更多还原
