Abstract
This paper deals with optimum design problems of an active variable trapezoidal hump. The objective function to be minimized is the difference between the maximum accelerations of the driver for the hump and those for an ideal hump. Design variables are the full length, the flat length and the height of the trapezoidal hump. In this paper, we give the height of hump upper and lower limits. As a result of the optimization, it is clarified that the optimum dimensions of the hump were obtained, and the optimum active variable hump was able to have an ideal characteristics.
