首发时间:2012-12-04
摘要:水润滑橡胶轴承摩擦噪声测试系统是用于研究水润滑橡胶轴承各种工况下的摩擦噪声。实际测试中,由于环境噪声信号的干扰,很难准确反映水润滑橡胶轴承的摩擦噪声,所以需要对系统进行改进。本文旨在设计一种隔音装置,能有效隔离环境噪声信号。通过对一种螺旋槽水润滑橡胶合金轴承的实验,结果表明设计的噪声隔离装置能有效地抑制外界环境噪声。

Research sound insulation device at a friction-induced noise measurement system
Abstract:The measurement system of friction-induced noise of the water-lubricated rubber bearings is the medium to the study of friction-induced noise of the water-lubricated rubber bearings under the various working conditions. Due to the fact of measurement data corrupted with the external noise, the system needs to be improved. The paper aims at designing a sound insulation device, which can inhibit the external noise. The experiments of water-lubricated rubber alloy bearings and the results demonstrated that the designed noise isolation device can inhibit the external noise effectively.
Keywords: water-lubricated bearings sound insulation friction-induced noise
