Abstract

In this paper, the static stress calculation and fatigue analysis of the connecting rod of the crab bait cutting machine are carried out by ANSYS Workbench software. The results show that the safety factor at the root of the connecting rod is about 0.65, which is prone to fatigue. The problem is improved by increasing the cross-sectional area, and the response surface parameter optimization design is used to seek the optimal solution of each parameter of the connecting rod with the minimum safety factor and quality of the connecting rod as the goal. Finally, three candidate schemes are verified to obtain the best scheme. The quality of the optimized connecting rod is reduced by 10.52%, and the minimum safety factor on the connecting rod is 1.02, which improves the reliability of the connecting rod.
