根据标准ASTM E756-05(2010)，对阻尼橡胶材料阻尼性能悬臂梁共振法的测试方法进行了研究，分析接触式响应传感器引入的附加质量及激励传感器和响应传感器的安装位置对测试结果的影响，并得到有意义的结论。试验结果表明：质量为0.6 g的接触式响应传感器引入的附加质量对材料的弹性剪切模量和剪切损耗因子的影响较小，测试结果满足标准ASTM E756-05(2010)对测试精度的规定；选择合适的激励器安装位置有利于提高传递函数曲线幅值；响应传感器的安装位置对传递函数曲线影响较大，测试时应根据所要获得的模态信息选择合适的测点。

The vibration damping properties of damping rubber materials were tested according to ASTM E756-05 (2010) based on the cantilever resonance method. The effects of the additional weight induced by the contacting response transducer and the arrangements of the exciter transducer and response transducer were analyzed. The results show that the additional weight of the contacting response transducer with 0.6 g mass has little contribution to the shear loss factor and the shear modulus. The suitable arrangement of the exciter transducer can cause the increase of the FRF amplitude, and the arrangement of the response transducer has a large effect on transmission function curve. So, locations of the response transducers should be chosen reasonably according to the required modal signals.
