ANALYTICAL METHOD OF MEETING PASSENGER'S INJURY PROTECTION DIRECTIVE IN ACCORDANCE WITH LUGGAGE INTRUSION UNDER HEAD-ON COLLISION

摘要

Analysis method to satisfy passenger injury protection legislation of the luggage intrusion upon the disclosed vehicle head-on collision, the steps constituting the (a) half of the model vehicle and the vehicle body; (B) making the body part to the same simulation and the experimental conditions presented in passenger injury protection laws according to the event of a vehicle frontal collision baggage enters the body, dew acceleration by integrating the values ​​corresponding to the codes acceleration rate curve the step of setting a test with red; (C) step of setting the boundary conditions to consider the acceleration of gravity effect on the model, and obtaining a speed of the collision immediately before giving the initial speed to the vehicle body, and the simulation from the time of collision and; (D) setting a keontekteu conditions using an automatic keontekteu and; (E) step of setting the end time by performing the analysis at a predetermined time; And in that it characterized in that it comprises a; (f) analyzing a result of performing the analysis in said step (e) and evaluated, and reflect this in the design. According to the invention, the pull out the best performance in a short time by using a computer analysis method achieved in the vehicle passenger safety and satisfy the regulations enhance the commercial value and, the number of the BIW for use in crash tests by using a computer analysis there is an advantage that can be saved.
