液压剪叉升降平台动力学仿真分析

摘要

以单液压缸推动3副剪叉机构为研究对象,对机构进行结构分析,将液压剪叉升降平台按其结构划分成不同的组件模块,根据其结构特征建立了基本数学模型,运用虚功原理对模型进行分析计算,推导建立各模块求解计算的表达式,使结构整体计算简化.分析起升油缸压力和各铰点受力,然后用Analytix软件进行仿真验证,为设备的安全使用和受力研究提供了依据.%Taking the single hydraulic cylinder pushing 3 pair of scissors fork organization as an example, ir analyzes its institutions function.It divides the hydraulic shear fork lift platform into different modules according to its structure, establishes their basic mathematical mode, simulates these models with the virtual work principle and Analytix software, obtains the cylinder pressure and the hinge point force.This provides the safe use of devices and mechanical research basis.
