Title

CAE Of Vehicle Frontal Crash Analysis And Seat Design

Authors

Abstract

Vehicle frontal crash simulation calculation is conducted by LSDYNA. Energy absorption area and transmission route of impact force in frontal crash are introduced in details. Affects of longitudinal beams deformation on vehicle crashworthiness are discussed deeply through simulation of the longitudinal beams design plan. Finally, tests are made to verify feasibility of the longitudinal beams design plan and reliability of the vehicle frontal crash model. As result, references are provided for vehicle longitudinal beams design and improvement for the future and moreover this paper used the Hyper Mesh and LS-DYNA software to establish a dummy-seat finite element simulation model. The head, chest and neck injury of the dummy were analyzed respectively in the frontal impact and rear impact. It was indicated that modification of seat was needed to meet the requirements. The simulation results showed that the original model cannot provide effective protection for the occupants and need for structural improvements. According to the simulation results of deformation and stress conditions of the seat parts, the original seat structure was improved and optimized for four improvement schemes, including the structure optimization of the seat side panel, the center hinge, framework under the cushion and the backrest lock.
