| 中文摘要: |
| 目的 归纳出高温范围内减振系统动态性能随温度变化的关系。方法 通过在特定温度条件下使用正弦扫频以及半正弦冲击试验，测试一系列压剪型橡胶减振器振动以及冲击性能，使用最小二乘法拟合得到此类减振器多个振动冲击性能与温度关系的经验公式。结果 在低于橡胶材料热分解温度的前提下，短期内压剪型橡胶减振器的动态工作特征与工作温度有关，与温度历程无关，均可表示为温度的三参数函数。结论 随着温度的升高，一阶谐振频率(ωT)以及冲击响应幅值的绝对值(GT)遵循一阶指数衰减函数关系，放大倍数(DT)与温度则遵循S型函数关系。 |

| This paper aims to provide the correlation between dynamic performance and temperature in high temperatures. In a series of high temperature conditions, the vibration and impact performance of isolators are tested. Some empirical formulas are summarized through those results using the least square method. The test results show that the dynamic performance of pressure-shear rubber isolators are related to temperature rather than temperature history. Furthermore, the first-order resonance frequency (ωT) and the absolute value of the impact response acceleration (GT) follow the first-order exponential decay function relationship with the changing of temperature, and the amplification factor (DT) follows the S-type function with the temperature. |
