Abstract
A lot of electric vehicles have usually adopted the ASF(Aluminum Space Frame) type rather than the monocoque or unitary construction type since the first is easier to reduce mass efficiently with the required stiffness and strength. Through the structural analysis, LSV(Low Speed Vehicle) performances such as stiffness and strength are evaluated. Based on the structural analysis, the optimization formulation of the ASF is set to decrease mass with satisfying stress and stiffness constraints. While it is assumed that sectional shapes of the members in ASF are fixed, the optimum thickness of members is determined. Through the optimization, the members that play important roles in the static stiffness improvement are found. Finally, the performances of the initial design and the optimum design are compared. The structural analysis and optimization are performed using the commercial software, FEMB/GENESIS Ver.7.0.
