【Abstract】 With application of Pro/E Wildfire software, the physical model of main parts in gear-box is established. It can realize virtual assembly and interference check of the mechanism. Using ADAMS software, a virtual prototype of gear box transmission system is set up which can simulate the movement in real conditions and evaluate the variation curves of the displacement, velocity, acceleration and force with the time. A counterweight balancing device is designed on the basis of simulation results. It is shown from the results that the parts to be assembled in gear-box have no interference and the parts’ structure design is reasonable. Through simulation on the displacement/velocity/acceleration curves of nine pistons, the feasibility of simulation model establishment of transmission system is verified. The designed counterweight device can largely reduce the fluctuation of reacting force on the bearing of gear-box.更多还原
