如何提高液压升降机的稳定性？

在进行升降机设计时，对升降机稳定性进行分析是非常必要的，下面5点忽略因素。It is very necessary to analyze the stability of the elevator when the elevator design is carried out in Shanghai, and the following 5 factors are ignored.

1.升降机上、下作业臂、支腿、轮胎等都具有足够的刚度，不考虑升降机升降机的柔性。Shanghai elevator, the lower operating arm, legs, tires and so on have sufficient stiffness, do not consider the flexibility of the elevator lift.

2.升降平台液压缸的质量变幅很小，不会对升降不稳产生影响，忽略不计。The quality of the hydraulic cylinder of Shanghai lift platform is very small, which will not influence the fluctuation of the hydraulic cylinder.

3.升降货梯作业时，用4条支腿作支撑，而所有轮胎都完全离开地面。Shanghai lift cargo operations, with 4 legs for support, and all the tires are completely out of the ground.

4.将升降平台工作平台及其载荷看作一个集中载荷固结在上作业臂末端。The working platform of Shanghai lifting platform and its load is regarded as a concentrated load which is fixed on the end of the upper working arm.

5.升降机上、下作业臂为匀质杆状结构，其质心在各臂的几何中心位置将工作平台及其载荷看作一个集中载荷固结在上作业臂末端。The upper and lower operating arms of the Shanghai elevator are a homogeneous rod structure, and the center of mass of the upper and the lower working arms are regarded as a concentrated load of the working platform and the load is fixed on the end of the upper working arm.
