由声激励引起的结构振动对车载机组舱降噪性能的影响

The Effects of Structural Vibration Caused by N oise to Generator Cabin's Noise Reduction Per formance

作者利用ANSYS软件提供的声 结构耦合分析平台,对军用野战通信车车载动力电源机组舱声场进行了数值模拟,分析了由其声激励引起的结构振动对机组舱降噪性能的影响,并提出了相应的控制方案,这对于提高车载机组舱的降噪性能有着重要的意义。

Using ANSYS's noisestructure f initeunit analysis technology,the authors made a noisefield numerical simula tion of the generator cabin and analyzed the affection of structural vibration c aused by noise to generator cabin's noise reduction performance,and gave corresp onding steps for progress.All of above has great meaning to enhance generatorc abin's noise reduction performance.
