Abstract

Dynamic explicit finite element analysis is practical and significant to study vehicle spiral rolling. By means of HyperMesh and LsDyna, numerical simulation is achieved with deformation, posture and acceleration obtained. During spiral rolling process, vehicle roof comes much close to occupant head step by step, so vehicle roof should be intensified and optimized moderately. Initial impacting velocity is set as 80km/h, dummy does not leave the seat until the rolling ends with safety belt adopted. While, without safety belt, dummy detaches or contacts vehicle for several times, head and neck have relatively large deflection and bending. Without the protection of the safety belt, the injury of head, neck and chest during spiral rolling goes beyond the regulation requirements for safety, serious casualties will occur consequentially.
