肘杆机构运动周期中的有限元分析

有限元分析技术的应用,对于缩短产品开发周期、提高产品质量、降低制造成本具有重要意义。通过有限元分析软件Ansys Workbench,对影响压力机传动精度和安全性的主要部位—变形肘杆机构进行有限元模型的建立,并对其进行整个运动周期中的强度分析,从中获得主要传动杆件在机构的整个运动周期中的应力分布规律,最后通过显示超过应力极限的部位,分析产生的原因,从而优化结构,保证机构运动的安全性。有限元分析方法为产品的开发生产和安全使用提供了保证。

Finite element analysis of elbow-bar in cycle of motion

It is significant to apply the finite element analysis technology in the design,which can shorten the development cycle,improve product quality and reduce manufacturing cost.A finite element model for elbow-bar mechanism-main part that may influence press transmission precision and safety was established through the finite element analysis software Ansys Workbench,which strength in cycle of motion was analyzed,and then stress distribution law of the main transmission driving link in the whole cycle of motion was obtained.Finally,through displaying the position exceeding stress limit,the causes occurred was analyzed,thereby the structure was optimized and the safety of the mechanism was guaranteed.In one word,the finite element method provides security for the development and safe operation of the product.
