| Abstract: | Based on the principle of multi-body system kinematics,both forward calculation of multi-body kinematics for overhead cam valve trains and reverse calculation of cam profile based on valve lift data and gauge displacement data obtained by various production inspection measurements are presented.And a forward / reverse combined calculation of valve train kinematics is put forward,which can reversely obtain the cam profile data more accurately.It is shown that these analyses can efficiently resolve various kinematical problems resulting from the design,manufacture and inspection of valve train. |
