本文叙述了剪叉式液压升降平台力学计算微机程序设计所采用的原理及力学模型和程序运算过程,作者在计算上采用了虚功原理,将剪叉式升降台的叉架机构按某一瞬时位置作为静力结构进行计算,由于升降平台叉架机构起升速度慢,此计算也是一种可行的方法。 This paper describes the principle of the computer program design of the mechanical calculation of the scissor type hydraulic lifting platform, the mechanical model and the program operation process. The author uses the principle of virtual work to calculate the fork mechanism of the scissor lifting platform at a certain instant. The calculation of the position as a static structure is also a viable method due to the slow lifting speed of the lifting platform fork mechanism.
