摘要
本文采用新的声振测试技术—表面声强法,对自行火炮变速箱进行了在线测试。通过采用隔声筒和求取表面声强值能剔除其它设备的干扰,成功地解决了强背景噪声下变速箱的在线测试问题。
The new sound-vibration measuring method梥urface intensity measurement is used 10 test the gearbox of self-propelled gun in situ. The other vehicle's disturbance is got rid of by sound-insulated-tube and the value of surface intensity. The problem of testing the gearbox in situ under the strong background noise is solved successfully.
