水润滑橡胶轴承在低速、重载、润滑不良状况下,会出现异常振动与鸣音,严重影响水下航行器的隐蔽性与生存能力,因此开展鸣音机理研究具有重要的理论意义和工程实际应用价值。该研究主要通过理论分析和台架模拟试验,利用Pulse振动分析平台对艉轴试验台架的振动情况进行数据采集和频谱分析,揭示鸣音产生机理以及载荷、线速度、温度等因数对鸣音的影响规律。
水潤滑橡膠軸承在低速、重載、潤滑不良狀況下,會齣現異常振動與鳴音,嚴重影響水下航行器的隱蔽性與生存能力,因此開展鳴音機理研究具有重要的理論意義和工程實際應用價值。該研究主要通過理論分析和檯架模擬試驗,利用Pulse振動分析平檯對艉軸試驗檯架的振動情況進行數據採集和頻譜分析,揭示鳴音產生機理以及載荷、線速度、溫度等因數對鳴音的影響規律。

Under the condition of low-speed, heavy-load and poor-lubrication, the water-lubricated rubber bearing can vibrate abnormally with its spirant occurring, which can seriously affect the imperceptibility and viability of the underwater vehicles. Therefore, a detailed research of mechanism of the spirant is of important theoretical significance and practical application value. In this paper, a Pulse vibration analysis platform was used for data acquisition and frequency spectrum analysis for the stern-bearing test-bench. The mechanism of the spirant was revealed, and the influence of the load, linear velocity and the temperature on the mechanism of the spirant was discussed.
