Abstract:
Heavy vehicle cabs of the ‘cab-over’ type construction have very little structure in front of the driver which can be used to absorb energy during a frontal collision. As part of a project to develop a crashworthiness standard for Heavy Goods Vehicles (HGV) cabs [1], a phase of dynamic computer simulations was carried out. The simulations used Finite Element (FE) models analysed with the LS-Dyna3D software, and concentrated on ‘cabover’ type vehicles.Typical accidents, involving frontal collisions, were reconstructed for potentially survivable truck to truck impacts. The residual space was defined by the geometry of a 95%ile dummy and it’s intrusion was recorded for each analysis.Also using dynamic simulations a Type Approval-like test scenario was developed which was representative of the generic frontal impact accidents.A summary of all the simulation results is presented by this paper.
