| Abstract: | In this paper the measured cam profile is analyzed through the establishment of valve-train kinematics and dynamics simulation model.The reversing optimization design of the survey cam profile is discussed in retaining the former CAM lift characteristics.Through optimizing design of the cam profile,the dynamic characteristics of valve-train was guaranteed,including valve vibration speed and the contact stress of cam.The second-order continuity of the cam profile was ensured,promoting the processibility. |
