Abstract Today, tuning of hydraulic vehicle shock absorbers is still mainly an empirical and iterative process performed in ride tests. The used valve systems are based on shim stacks which provide a wide behavior variety by millions of different shim combinations where, however, many shim stack variants have rather similar stiffness or flexibility characteristics. In this paper, a strategy based on finite element analysis and numerical optimization is presented for finding an optimal stacking. It allows to automatically identify shim stacks with similar flexibility characteristics taking into account limitations for specific design parameters which may for example improve and cheapen the serial production process. This strategy can also be exploited by transforming the shim stacks resulting from the physical tuning dampers used in ride tests into more robust shim stacks regarding the influence of manufacturing tolerances which are always present in mass production.
