| Abstract: | Aimed at the symmetric and offset crank-slide mechanism in combustion engines, mathematic model of their kinematics and dynamics were set up, calculation and simulation results were given by using software MATLAB. Based on these, the kinematic and dynamic characteristics of the two type of symmetric and offset crank-slide mechanism were compared. It was shown by the results of calculation and simulation that piston offsetting and increase of its offset distance could improve dynamic characteristics of combustion engine. |
