| The work aims to analyze and optimize the design of the elbow bar of the die-cutting machine with ANSYS finite element software, to realize the high-precision, high-reliability, and high-speed smooth operation of the high-speed and heavy-duty die-cutting mobile platform. The Adams dynamic analysis method was used to analyze the motion displacement, speed, and acceleration of the transmission elbow bar, to obtain its curves, and analyze whether it met the motion laws of the die-cutting machine under heavy-duty and high-speed motion conditions. The Newton Euler method was adopted to solve the dynamic problems of complex multi rigid body motion systems and the numerical solution of the force on the lower elbow bar was obtained. The finite element analysis software was used to perform finite element analysis on the transmission elbow bar of the mobile platform, and the cloud map of stress and strain under a certain pressure was obtained. Comparative analysis was conducted with the numerical solution to determine whether the lower elbow mechanism met the requirements of heavy duty. The stress cloud map and deformation cloud map of the elbow bar component were obtained and the maximum stress of each component was determined to be 469.1 MPa.The use of finite element analysis to guide the structural optimization design of the die-cutting pressure test platform from a theoretical perspective has improved the accuracy of the design and shortened the trial production cycle of the product. |
