以四连杆机构的弹性连杆为研究对象,采用运动弹性动力学分析,求取振体表面法向速度;对其运动过程中的声辐射功率及结构模态声辐射效率进行了预测,为梁类高速运动弹性构件的声辐射控制提供了理论依据。
Taking the elastic connecting rod of four-bar mechanism as the research object, the kinematic dynamic dynamics analysis was used to obtain the normal velocity of the surface of the vibrating body. The sound radiation power and the structural mode sound radiation efficiency during the movement were predicted as The theoretical basis of acoustic radiation control of beam high-speed elastic members is provided.
