ソーラーカーにおけるサスペンション剛性が操縦安定性に及ぼす影響

抄録

In recent years, the automobile industry has been required to reduce the weight of automobiles due to environmental problems. Although reducing the weight of a vehicle has advantages such as improved fuel efficiency, the reduced rigidity affects running performance. In this study, we investigated how the response performance of the vehicle changes by changing the stiffness of the suspension using theoretical formulas. From the calculated results, the relationship between suspension rigidity and steering stability was evaluated. As a result, it was found that the steering stability is greatly affected not only by the rigidity of the entire suspension but also by the rigidity ratio of the parts. Therefore, we aim to evaluate the rigidity and steering stability of the suspension so that it will not be affected by the shape of the suspension by examining the difference between the vehicle running test, analysis, and theoretical formula.
