| Abstract: | In this paper,the dynamic stiffness matrix method is used to predict the vibration of the crankshaft system and to calculate the input exciting force from the crankshaft to the slide rod.Then,a finite element model of the whole power transmission device system is established.The proposed model is finally adopted to forecast and calculate the vibration.The calculated results accord well with the experimental results,verifying that the proposed method is correct and practicable. |
