The invention continues the numerical simulation directly from a certain flutter time, which can skip the flutter process, and directly obtain the time when the flutter ends and the positions and velocities of the two colliding objects at that time, thereby increasing the calculation accuracy and reducing the calculation time.Descriptions with Drawings Obtain model input parameters at the time of flutter Establish a first solution model to obtain the end time the flutter |Establish a second solution model to obtain the S position parameters of the two colliding objects S3 at the end time of the flutter Establish a third solution model to obtain the velocity parameters of the two colliding objects at the end time S4 of the flutter Fig.1 1 2 Fe(sinD1) Fig.2
