円弧ハンプの多目的最適設計 : ハンプが弾性を有する場合

抄録

In the previous paper, a hump with elasticity was proposed, and numerical analysis was carried out on the hump in order to determine the influence of the elasticity on speed control for vehicles. In this paper, circular humps with elasticity are designed using a method of multiobjective optimum design in order to minimize the maximum value of the maximum accelerations of the drivers occurring while various vehicles cross a hump at a design speed for the hump and to minimize the maximum difference between the maximum accelerations of the drivers. The set of Pareto optimal solutions is obtained using the weighted Tchebycheff norm method. In addition, relations between the maximum acceleration of the driver and speed of the vehicle are analyzed numerically for each vehicle crossing the optimum elastic humps and an existing rigid hump.
