基于MathCAD的单层剪叉式液压升降平台的设计

Development of the single layer shear-fork type hydraulic lift platform based on MathCAD

为解决剪叉式液压升降平台结构传统设计方法存在的参数变化趋势求解困难的问题,以某单层升降平台设计为例,借助MathCAD软件,对油缸运动过程中各个位置的受力进行曲线分析,找到了最佳设计参数。基于MathCAD软件的设计方法主要包括结构设计、液压缸相关参数的计算和销轴的校核,并给出了最终的三维设计模型。文中推导的公式,对液压驱动的升降平台的设计,有一定的工程借鉴意义。

It is difficult for traditional design method to solve parameter change trend in shear- fork type hydraulic lift platform. Taking the single layer shear- fork type hydraulic lift platform as an example,it analyzes the curve of the force at the different location in oil cylinder movement process,obtains the optimal design parameters. The design based on Math CAD includes structure design,the calculation of oil cylinder parameters and key parts evaluation,builds the 3D model. The derived formulas are very useful for the design of hydraulic lift platform.
