基于AutoCAD VBA和ANSYS的开卷机传动花键应力分析

Stress Analysis of Decoiler Spline Based on AutoCAD VBA and ANSYS

结合武钢硅钢ZR3开卷机的传动花键应力分析研究,利用AutoCAD二次开发工具VBA对开卷机花键进行参数化设计、建模,将几何物理模型转变成具有单元概念的可分析模型,完成网格的自动剖分,并在ANSYS中进行应力和应变分析,为优化花键参数提供了依据,从而显著地提高了整个开发进程的效率,同时也为类似问题的研究提供了一种有效的参考途径。

This paper analyzes the stress of driving spline on silicon steel ZR3 decoiler that used by Wuhan Iron and Steel Corp.Using the secondary development tool VBA of AutoCAD to achieve the parametrization design and the modeling of the spline of decoiler,and convert the geometric model into the analyzable models which having the concept of element,so the automatic segmentation of ridding has achieved.The stress ＆ strain were analyzed by ANSYS,it can provide the principle for optimizing design of the spline parameters,and the whole development efficiency has been enhanced greatly.At the same time,it presents an effective reference way for the people who doing similar study.
