摘要

It is very effective to spread electric vehicles into the world to solve the environmental and energyrnresource problems in our automobile societies today. We have developed an 8-wheel EV namedrn'KAZ(Keio Advanced Zero emission vehicle)', in which three new technologies of In-Wheel-Motor,rnComponent-Built-in-Frame, Tandem-Wheel-Suspension are applied. KAZ demonstrates progress inrnlarger-space and high performance(maximum velocity 311km/h).rnThis study is aiming to developing a mini bus applying the technologies verified with KAZ. This paper isrnconcerned with body structure for the mini bus. The hollow beam shell is proposed as a body structure.rnThe hollow beam shell is composed of many uniform hollow beam members and achieves a lightweightrnand rigid, high insulation efficiency body. Frame model of mini bus applying the hollow beam shell isrndesigned and evaluated by FEM analysis. The analysis result indicates that the flexural rigidity andrntorsional rigidity of the proposed body are 281% and 256% greater, respectively, than those of the bodyrnstructure designed for KAZ2 improved from KAZ in rigidity. These results are achieved with only 9%rnincrease of the body weight from KAZ.
