| Abstract: | Based on the requirement of the motion of internal-combustion engine distribution cam,the cam curve is protracted and the mechanism model is designed on the UG platform.In Scenario,for motion,the simulation is made combined with ADAMS.Then the simulation creates the curve of displacement,velocity and acceleration of the cam mechanism.The final curve is close to the theoretic requirement.This result of simulation could be feed back to the CAD module to modify and perfect the parameters and assembly relationship of the mechanism. |
