| 摘 要： | 从时温等效原理出发,依据WLF方程和自由体积理论推导了一个较为简单的将高分子材料的温度谱转变为频率谱的方法。用该方法计算得到的损耗因子与实验数据吻合得很好。研究了所合成的聚氨酯材料在1～10000Hz范围内的特征阻尼频率.结果表明25℃下.含填料的H052的特征阻尼频率为5430Hz。

| Abstract: | Damping properties of polymer materials varye with frequency of stress working on them when the temperature is constant. According to WLF equation and free volume theory respectively, the relationship between damping property and frequency is abtained. The results of experimental check show that the origin curve consists satisfactorily with experimental curve. |
