摘要: 为解决大型履带式推土机行走系减振的新课题,对其行走系的振动状况进行了测试,确定驱动轮为需实行减振的关键部件。根据推土机的实际结构及作业要求,对多层管状组合阻尼结构的减振装置进行了开发研究,进行了理论按摩及试验验证。经过实车对比试验,结果表明安装了阻尼减振驱动轮的推土机驾驶座椅处的振动水平值下降了9dB。

Abstract: For solving a new vibration isolation problem in undercarriages of heavy duty crawler-type bulldozers, tests are performed for determining the vibration conditions in the undercarriages. The test results show sprockets are important parts to be isolated vibration. The developmental studies for isolators with multiple tube damping composites are carried out according to structures and work conditions of the bulldozers. Theoretical analyses and experimental verification are also carried out. After a contrast experiment in a practical bulldozer, the date indicates that the vibration decibel values reduce 9 Db on the chair of the bulldozer installed the isolators.

Key words: Crawler-type bulldozer Undercarriage Damping Vibration isolation
