Examples
- Taking gear case as research object , we studied the sound radiant efficiency of complex box - shape structure under practical stimulation by experiment , mainly observed the difference of sound radiant efficiency between the complex structure under practice stimulation and the known simple structure
以变速箱为对象，对实际激励条件下箱形结构的声辐射效率进行了试验研究，重点考察了这种结构在实际激励下的声辐射效率同已知的简单结构声辐射效率的异同以及激励的改变对辐射效率的影响。 - By experiment , we found that the variation of gear case radiant efficiency with frequency keep accordance with that of simple one as a whole , but the radiant efficiency of gear case will go beyond any calculation result of empirical formula when the frequency is below 250hz . we also found that stimulation changes affect radiant efficiency little by varying speed experiment , and it can be ignored in engineering calculation . the rectangle structures as gear case , possess characters of both plane and ball , and their sound radiant efficiency lie between plane and ball region
通过试验发现，总体上变速箱辐射效率随频率的变化规律同简单构件的辐射效率是一致的，但在250hz以下的低频区域，变速箱的辐射效率大大高于任何一个经验公式的计算结果；通过换档试验发现，激励的改变对辐射效率的影响不很显著，工程计算可以不予考虑；对于变速箱这类三个方向尺寸差别不大的结构，其辐射性质具有平板和球源的双重特征，辐射效率介于平板和脉动球源之间，据此提出在工程应用时可以取平板和脉动球源辐射效率的平均作为此类结构辐射效率的观点。
