Recently, vehicle components like gasoline direct injectors are developed based on 1 dimension simulator which can be applied to the early design stage of product development. Further, the vehicle components are more complex structures to achieve high performance, and the impact behavior is more complex. Therefore, in order to estimate performance of components, rapid and high-precision method to calculate impact behavior is required on early design stage. In this paper, we show the method, which provides the impact simulation method by using eigenvectors to clarify impact phenomena. We applied this method to impact phenomena for direct gasoline engine injectors. This method can reduce elapsed time by approximately 84 percent than explicit method of full matrix and clarify predominant vibration mode in impact states.
