Dynamics Analysis and Optimization of Gear Transmission System

The gear transmission system was parametric modeled in the software Pro/E to establish the prototype, and imported into ADAMS. The meshing force curves of time domain and frequency domain were reached through dynamic simulation. Then the gear system was optimized with several constraint conditions, such as the number of surface modes, helix angle, cutting conditions, minimum tooth width, the contact fatigue strength, and tooth root bending fatigue strength. The optimization was calculated with these constraint conditions, and got the best design of gear system. After optimization, the gear transmission system was simulated again to reach the dynamic analysis and made a contract with the former simulation results. The simulation of the optimized gear system shows that the optimized gear has good mechanical properties.
