Abstract


30 years of reform and opening up in China to promote the rapid growth of the economy , the number of cars in China to maintain the momentum of sustained growth , but the car traffic accident has been high , especially the automotive side impact occupant injury is more serious in all accidents . Therefore major car companies and research institutions on the side of the car collision put a greater effort . Our vehicle side impact safety regulations introduced in July 2006 , which laid the foundation for China 's progress in the automotive side impact . The strength and stiffness of the door and its reasonable degree of occupant injury and regulations is very clear on the side door strength requirements . In this paper, the finite element simulation method to optimize the design of the car front door crashworthiness . The optimized collision beam and Importing door model validation . The side of the car after the collision research work to open up the road . Based on nonlinear finite element theory , the door material properties by using LS-DYNA analysis , finite element analysis of a number of influencing factors discussed Door Side collision , so as to formulate a non-linear finite element analysis . modeling, a preliminary study of the non-linear finite element modeling and simulation process control parameter selection problem . Requirements, then the side door of the U.S. Federal Motor Vehicle Safety Regulations strength tests (FMVSS214) doors with rigid column to establish a simplified collision model, the door structure performance analysis , and with reference to the appropriate laws and regulations to the side crash simulation analysis . Computing for door model crashworthiness analysis and optimized collision beam into door model , a comparative analysis with the installation of the original bumper beam door , through the use of crash board instead of the bumper and the original bumper the circumstances of the collision , collision avoidance board structure optimization . After the optimization , instead of the original bumper is installed in the vehicle , again side collision simulation , structural deformation , improved to varying degrees of absorption energy, stress distribution than the original bumper , to verify the feasibility of the optimized .
