Abstract: In this paper, a refined subdomain model of a rear door lock system is established by using multi-domain technique in RADIOSS. The reasons are analyzed to understand why the rear door opened during side impact, and corresponding countermeasures are put forward. An effective resolution plan is proposed to provide virtual simulation support for engineering design. It shows that the multi-domain technique in RADIOSS brings a new solution method for simulations with locally refined and more accurate models.
Key Words: multi-domain technique, side impact, simulation, door lock, RADIOSS
