ABSTRACT: This paper is devoted to the problem of finding optimized parameter
combinations of automotive damper modules. Different cost functions using the
amplitude spectrum of the excitation and the frequency response function of the
car model will be investigated and it is shown that for three different
arbitrary road excitations there exists a parameter combination of top mount
stiffness, piston rod mass and damping constant that provides an optimum for
the dynamic wheel load fluctuation. The achieved advantage of the optimized
damper module regarding the dynamic wheel load fluctuation compared to a simple
damper in a two mass vibration system can reach up to 20 percent.
