A KINETOSTATIC METHOD FOR THE DESIGN AND STUDY OF VEHICLE CRASHWORTHY COMPONENTS FOR LOW-SPEED IMPACT

A kinetostatic methodology based on the concurrent use of multibody dynamics computational tools and nonlinear finite elements is described and used here for the design of vehicle energy absorbing components. The vehicle is modeled as a multibody system based on the joint coordinate method which allows that the equations of motion are generated in a systematic form and that elastodynamic effects are included. The large deformations associated with the crushing of the energy absorbing components are analyzed with a nonlinear finite element code and the results are incorporated in the multibody model of the vehicle using crushable elements. The vehicle is studied for several frontal and oblique impact situations at different speed. Based on the results, the performance of the device is discussed.
