| 摘 要： | 现有国内舰船上的减速齿轮箱往往都刚性固定在船体基座上,个别舰船齿轮箱采取硬弹性连接,隔振效果不理想。当主柴油机采取隔振措施后,传到船体基座上的振动加速度会明显减少,齿轮箱传到船体的结构噪声成为影响舰船辐射噪声的主要噪声源之一。通过对齿轮箱浮筏模拟试验装置的设计、建台及试验,研究舰船减速齿轮箱隔振问题。试验结果表明,齿轮箱浮筏模拟试验装置的隔振效果可达25dB。

| Abstract: | In ship construction of our country,the gear case is usually rigidly fixed on the base of the ship body,and sometimes the gear case is connected to the base with hard springs.The effect of vibration isolation is not good.The gear case＇s structural noise,which spreads to the ship base,becomes the main radiation noise source of the ship.In this article,through the designing and testing of the gear-case raft installation,the gear case＇s vibration isolation problem is studied.The test results indicate that the vibration reduction level of the gear-case raft installation can reach 25dB. |
