【Abstract】 A calculation criterion of harmonic cam with constant acceleration for fuel injection pumps is presented. The cam profiles with constant acceleration section can be conveniently calculated. This method can be used to control the accleration oscillation in the working section and to reduce the contact stresses. Based on the analysis of common velocity characteristics, a generalized velocity charcteristics and related boundary conditions were established for fuel injection pump cams and a computer program was compiled for harmonic ones. Suggested method is also applicable to calculation of other types of cam mechanism.更多还原
