滑移装载机振动噪声控制研究
|
摘要
滑移装载机是常见的小型多用途工程机械车辆,其结构紧凑,如何有效降低传入驾驶室的振动噪声是研发中的重点。应用仿真与试验相结合的方法,对滑移装载机的振动噪声控制问题进行研究,提出整机减振降噪技术方案。通过整机减振降噪技术方案,使滑移装载机的噪声满足欧盟的要求。
The skid steer loader is a multi-purpose construction machinery vehicle with a compact structure. How to effectively reduce the incoming vibration noise in the cab is the focal point during research and development. By applying the combination of simulation and experiment to take the study on the vibration noise control of the skid steer loader, the technical scheme of vibration and noise reduction of the complete machine was proposed. Through the vibration and noise reduction scheme for the complete machine, the noise of the skid steer loader could meet EU requirements.
