Finite Element Analysis And Optimization Of Steel Cutting Machine Based On ANSYS Workbench

In this paper, GQ40 F type Reinforcing Steel Cutter currently on the market is used for the study. Its three-dimensional modeling was modeled and the whole assembly was done in Solid Works. The working animation of the Reinforcing Steel Cutter was recorded with animation module in Solid Works. At the same time, the kinematics analysis of the transmission mechanism of the Reinforcing Steel Cutter was done by the Motion module in Solid Works, exporting the graph of acceleration, velocity and displacement of the transmission mechanism movement and the working mechanism of Reinforcing Steel Cutter were further grasped from the perspective of kinematics.For GQ40 F shaft static theoretical analysis and finite element analysis by using was done. Based on the theoretical analysis, this paper got the stress condition of the transmission shaft. Based on the finite element analysis results,the total deformation, strain stress cloud and dangerous section of each shaft was obtained which laid the foundation for the subsequent improvement and optimization.From the point of view of theory and simulation, the contact analysis of GQ40 F Eccentric Shaft-Connecting Rod Mechanism was done and the expression of contact stress on the contact surface was obtained according to theoretical analysis. This paper output the stress cloud, contact pressure cloud and penetrate cloud through contact simulation analysis and found weak contact surface area which provided the basis for the proposed improvements. The theoretical analysis and simulation results were compared to verify that the model was reasonable.By fatigue analysis of the GQ40 F case, the safety factor cloud, life cloud,damage cloud and fatigue sensitive graphs was obtained. This paper explored the relationship between fatigue and life of the case and found the weak parts of the case to provide references for improvement and optimization.The transient dynamic analysis and research for GQ40 F transmission mechanism were done. From the perspective of dynamics the force andmovement related to load changes of the GQ40 F drive mechanism were studied which made up for the shortcomings of static analysis ignoring the inertial force and the damping to provide a comprehensive study for the cutter.By the improvements for the weak parts of the GQ40 F, this paper provides a favorable reference for the practical production. Optimized analysis for the box of the steel cutting machine was done by using optimization design module in ANSYS Workbench which provided reference for future research.
