ALTERNATE OPTIMIZATION OF SPEED CONTROL HUMP FOR AUTOMOBILES AND AUTOMOBILE SUSPENSION - (MINIMIZATION OF EACH SINGLE OBJECTIVE FUNCTION)

This paper deals with a study on the problem of minimizing each single objective function in two different design spaces. Whereas designers of automobile suspensions require that automobiles provide a comfortab le ride during all automobile speed ranges, designers of humps require that humps induce an uncomfortable riding condition when driving at s peeds greater than the hump design speed in order to indicate to the d river that he is speeding. Thus from the former standpoint, the maximu m acceleration of the driver should be minimized at a speed greater th an the hump design speed under adequate constraints for other maximum accelerations, and the optimum damping coefficients of the shock absor bers can be found. From the latter standpoint, the maximum acceleratio n of the driver should be minimized at the hump design speed under ade quate constraints, and the optimum dimensions of the hump can be prope rly designed. The above two optimization precesses are alternately rep eated and the optimum dimensions of the hump are confirmed.
