摘要
由于电动缸受轴向荷载时存在较大的轴向变形,对整体的定位精度和传动质量产生影响。因此,本文以某型电动缸为研究对象,拟对其关键结构参数进行优化。首先建立电动缸轴向变形的力学模型;提取关键设计变量;然后研究各关键部件参数对电动缸轴向变形的影响;最后进行相应的优化并通过数值仿真手段证明优化的有效性。结果表明:优化后变形量比原始设计减少了13.5%,本研究可为相关厂家提供一定参考价值。
Abastact:Due to the large axial deformation when the electric cylinder is subjected to axial load,the overall positioning accuracy and transmission quality are affected.Therefore,this paper takes a certain type of electric cylinder as the research object and intends to optimize its key structural parameters.Firstly,the static model for the axial deformation of the electric cylinder is established,and the key design variables are extracted.Then,the influence of these key parameters on the axial deformation of the electric cylinder is investigated.Finally,the corresponding optimization is carried out and the effectiveness of the optimization is proved by numerical simulation.The results show that the optimized deformation is reduced by 13.5%compared with the original design.This study can provide some reference value for related manufacturers.
