| 摘 要： | 基于壳体结构声振耦合理论，提出了一种由变速器振动面上的代表性测点的振动速度求该振动面辐射的噪声，再由各主要振动面辐射的噪声求变速器辐射的总噪声声压级的方法。试验证明该方法简单、快捷、准确，能够适用于汽车变速器或其他具有封闭箱体结构的噪声在线检测。

| Abstract: | Based on the coupling theory of shell structure surface vibration and its radiating noise, this paper introduces a simple, high efficient method which has been proved to be adaptable for the on-line noise measurement of the automobile gearbox. This method allows one to estimate the total sound pressure level of the noise radiated by the automobile gearbox from the sound pressure level of the noise radiated by its each main vibrating surface, which can be estimated from the vibration velocity of the representative vibration measurement point on the corresponding vibrating surface. |
