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.
