TWVs (Three Wheel Vehicles) are one of the efficient types of vehicle to increase driving distance for their low weight and air resistance, although TWVs are weaker in rollover than FWVs (Four Wheel Vehicles. Topology optimization is utilized for conceptual design and preliminary design of the roof structure for various loading conditions. The roof structure for TWV consists of existing part of FWV and a new part called Cross-bar reinforcement. Material of A-pillar and Cantrail is DP780, DP980 is for B-pillar, and DP590 is for member structures and C-pillar. Although a test method for regulation of roof strength is with static loading, simulations are carried out for dynamic cases considering real rollover crash condition. In the dynamic loading case, rate-dependency of a material needs to be considered for accurate results of FE analysis.
