Optimized Parameter Combinations of Hydraulic Damper Modules

Journal of Transportation Technologies, 2014
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 ...
