基于Workbench的Ⅰ-Lock螺旋升降柱静力分析

Static Analysis of the Ⅰ-Lock Spiralift Based on Workbench

螺旋升降柱及其构成的升降平台结构简单紧凑、易于控制,目前广泛用于舞台及各种工作平台的顶升。针对这种螺旋升降柱,介绍了其两种结构及工作原理。为进一步分析研究其静力特性,通过Solidworks对其"Ⅰ-Lock"结构某型号建立模型,导入有限元分析软件ANSYS Workbench,建立了适当简化的两种高度的螺旋升降柱有限元模型并分别分析最大静载工况下的静力特性,研究了载荷对不同高度螺旋升降柱应力、位移大小与分布的影响。结果一方面证明了结构符合设计要求,另一方面也为结构的进一步设计优化提供了参考。

Spiralift and the lifting platform are simple in structure and easy to control. They are widely used on the lifting of the stage and working platforms at present. This paper introduces the structures and the working principle of the spiralift. A specific model of its I-Lock structure is built in SolidWorks, and two simplified finite element models of different height are built in ANSYS Workbench then for further study on its static characteristics. The paper studies the effect of load on the value and distribution of stress and deformation of the two different height structures under the maximum static load condition. The result testifies that the structure satisfies the design requirements and provides a reference for the further optimization design on the structure.
