| 摘 要： | 分析了二级剪叉式液压升降机的三种主要布置方式,以及液压缸倾斜布置时的三种液压缸安装位置方案。对于其中的一种方案,应用虚位移原理计算求解液压缸推力,并以液压缸推力最小为目标建立优化设计数学模型,通过MATLAB软件得到液压缸推力最小时的液压缸安装位置。通过研究液压缸布置方式,提高了二级剪叉式液压升降机的设计效率和传动质量。

| Abstract: | The three main arrangements of the two stage scissor type hydraulic elevator were analyzed,as well as three schemes on mounting positions for the hydraulic cylinder when the hydraulic cylinders were tilted.For one of these schemes,the principle of virtual displacement was used to calculate the thrust force of the hydraulic cylinder.A mathematical model for optimization design was established with the objective of minimum thrust force of the hydraulic cylinder.The mounting position of the hydraulic cylinder when its thrust force is minimum will be obtained through MATLAB software.By studying the arrangement of the hydraulic cylinders,the design efficiency and transmission quality of the two stage scissor type hydraulic elevator were improved. |
