Analysis of Rubber Formula Selection based on the Transmission Property of Underwater Sound

为减少水声橡胶开发过程中的测试费用,缩短开发周期,对利用橡胶材料基本性能参数进行声波透射系数计算方法进行研究,然后利用透射系数理论计算结果对橡胶配方进行筛选。为验证该筛选方法的可行性,设计了三种橡胶配方,对其透射系数进行理论计算和性能测试,结果表明:3种配方橡胶的透射系数频率特性理论计算结果与测试结果吻合较好,数值偏差在5%以内,三种配方橡胶透声性能优劣排序理论计算结果与测试结果一致,证明了利用透射系数理论计算结果对橡胶配方进行筛选是可行的,透射系数理论计方法还可为橡胶配方设计提供指导。

In order to save the testing expenditure during the development of a specific rubber used in underwater environment and speed up the development cycle, the calculation method of transmission coefficients is studied by analyzing the basic parameters of the rubber. Then, the rubber formula is selected based on theoretical results of the transmission coefficient analysis. For demonstrating the reasonability of the transmission coefficient calculation method, three kinds of rubbers with different formulas are designed and their transmission coefficients are calculated and tested. Comparing testing results with the calculation results shows that both results are in good agreement with a small difference（± 5 %）. And the sequences of the three kinds of rubbers according to their acoustic transmission performance order are identical for presented calculation method and test method. It implies that the presented method is reasonable and feasible for rubber formula selection and the method can be used to guide the development of specific rubbers.
