摘要
探讨采用声学边界元法软件SYSNOISE进行汽车气动噪声数值计算的具体方法。以某型车为例,文章介绍了如何应用SYSNOISE软件建立汽车三维有限元声学分析模型,并采用有限元法对该车近场振动声学特性进行了计算分析。
Discussing substance method of using acoustic BEM software SYSNOISE to carry through numerical analysis of aerodynamic noise of automobile. Making a certain automobile for example, This paper introduced how to use SYSNOISE to establish three dimensions FEM model of automobile, and using FEM to calculate and analyze the vibration acoustics characters of the automobile in near field.
