摘　　要：阐述了矿山机械和工程机械中应用液压油缸推动升降机构和液压系统,在应用中当机构下降时产生剧烈振动,对机器造成不利影响。从原理上分析了产生问题的原因和影响因素,提出了解决问题的办法,并经实践证明取得了较好的效果。This paper relates the lifter frameworks with hydraulic cylinder and hydraulic systems in mining machines and engineering machines. In the application the frameworks bring exquisite vibrancy when they fall, and bring adverse influences for machines. On the basis of principle, the reason and influencing factors of the questions are analyzed. The means for solving questions is put forward, and taking good effect is proved through practice.
