发动机短舱声衬结构声振等效转换试验研究

摘要

基于载荷对结构造成响应的等效性机理，针对发动机短舱声衬结构开展声激励和振动激励的等效转换试验研究：应用载荷响应等效理论，分别进行声衬结构的噪声和振动试验，测试并计算其结构响应，给出了声衬结构在声激励和振动激励下的等效转换关系。试验研究能够有效改善试验的真实性，指导后续试验研究工作，具有良好的工程应用价值。%Based on the corresponding equivalence mechanism of structure response, a number of experimental research involving acoustic and vibration was conduct for engine nacelle liner. Combining corresponding equivalence of structure response with the consequence of experiments, equivalent conversion relations were presented for the liner structure in acoustic and vibration conditions. Experimental research in this article was of a great engineering application value and effective guidance for following study in this field.
