Abstract
A fast analysis method of vehicle body structure for offset crash test was investigated from the various parameters such as section properties, vehicle mass and crushable length in the engine compartment. A practical useful relationship between these parameters and the vehicle crashworthiness was determined. This method was very effective to implement a better new structure from the initial design stage before initiation of FEM simulation and to decrease iteration cycles by FEM simulation.
