直升机提升是进行起落架维护工作的基础,在起落架维护工作中占有相当的时间比例,以某军用直升机为研究对象,设计了采用闭环反馈控制原理的液压同步提升系统,给出了液压同步提升系统的组成,重点设计了液压回路,详细描述了直升机提升工作过程;该系统可以实现对直升机的同步提升,从而提高了起落架的维护效率。
Helicopter lift is the basis for the landing gear maintenance work, occupy a considerable proportion of time in the landing gear maintenance work. Taking a military helicopter as the research object, a hydraulic synchronous lifting system using the closed-loop feedback control principle is designed, and the hydraulic synchronous lifting System, and focuses on the design of the hydraulic circuit. The helicopter hoisting process is described in detail. This system can achieve the synchronous increase of the helicopter and improve the maintenance efficiency of the landing gear.
