由于作业时需要具有很高的安全性，因此吊具结构尺寸的设计和安全性检验便成为关键。在原有设计方法的基础上，利用UG7.5开发了吊具设计系统，并采用 ANSYS对吊具进行有限元分析。根据计算和有限元分析结果，优化了吊具的结构尺寸，实现了吊具在生产前的检验与优化。%Because of the high security requirements of spreader ,the structure design and safety testing of spreader have become important .Based on the original design methods ,a parametric design system of spreader was developed by using UG7 .5 ,and this paper conducted finite element analysis for the spreader with ANSYS .According to the results of the calculation and finite element analysis ,the structural dimensions of the spreader could be improved ,and the spreader could be inspected and optimized before production .
