STUDY ON CORNER CONTACT SHOCK OF GEAR TRANSMISSION BY ANSYS/LS-DYNA SOFTWARE

Solving gear meshing impact problems by using ANSYS/LS-DYNA software is studied. The mathematical model of gear meshing impact and collision is presented. The gear meshing-in impact process is simulated. The relationship between the impact velocity and the impact force, and that between the gear width and the impact force are given. The accurate impact time is obtained. A new approach for studying gear meshing impact is proposed here, and the numerical simalation results show that ANSYS/LS-DYNA software is a very useful tool for solving gear corner contact shock problems outside the normal path of action line.
