Abstract: Vehicle interiors are primary source of injuries when occupants interact with them in the event of an accident. The extent of injuries is depending on energy dissipating characteristics of interiors and severity of accidents. For side impact tests vehicle interiors energy dissipating characteristics are assessed by FMVSS214 and ECE R95. Side impact test assesses occupant protection by door panel as vehicle interior during side intrusion test on door. In this paper, a certain type of carís side impact performance is discussed. The purpose is to express the relationship of the side impact response during door trim intrusion and safety. First, A Finite Element Model (FEM) of door trim is established which is based on a logical method to solve the problem during the modeling process. Then, the analysis the evaluates the indexes of side impact safety, traces the designing, got the side impact feature and point test data of this type of car, and verified the practicability of simulation result in the door developing process. Finally, expresses the connection between the side impact response for door intrusion and safety of door, aiming at discussing the occupant safety during side impact. The FE model is produced using Hypermesh 11 softwares and LS-Dyna solver is used for the simulations. The simulation results shows side impact protection system is capable of absorbing and dissipating required energy for protection of Pelvis.
