Prediction of structural and kinematic coupled vibration on internal combustion engine

This paper deals with prediction of structural and kinematic coupled vibration on internal combustion engine. Many researches have been conducted in prediction of engine vibration. Most of them are categorized into two groups according to their targets and their methods. One is prediction of structural vibration in relatively higher frequency. The other is prediction of kinematic vibration in very low frequency. Nowadays, it is getting more important to treat coupled vibration between structural and kinematic vibration in middle range frequency while the demand of light weight and low friction rises. In this paper, we develop an engine vibration analysis system that can analyze structural and kinematic coupled vibration comprehensively in wide range. The validity of the system is discussed comparing the calculation results to the experimental results.
