| Abstract: | In this paper, the application of virtual design method in terms of reduction of engine vibration has been studied. Based on the 6108G diesel engine block, the prediction of vibration on the block surface is performed, and the results are analyzed by the viewpoint of vibrational magnitude and vibrational energy. To optimize the vibrational characteristic the improving scheme is presented, that greatly improved the vibrational characteristic of block skirt and bearing seats. It is a good representation for engine structure improving. |
