Abstract

Bolt connection is one of the common connection methods in diesel engine. The purpose of this study is to verify the difference of considering the bolt connection or not in the shock response calculation. The methods applying in the study as following: first design the comparison test of welding connection and bolt connection; establish the diesel engine’s fasten component model of considering bolt connection and model without considering bolt connection; then calculate the shock response of the two kinds of model by DDAM method; and finally coupling the shock response in three direction. The above tests reach the result that: the natural frequency of model without considering bolt connection is higher than that of the model considering bolt connection; the rigid connection area will easily produce stress concentration; and the stress concentration can be effectively reduced by considering bolt connection. Therefore, the study suggest that bolt connection should be considered in the study of shock response calculation of diesel engine frequency domain.
