We formulate the problem of optimising the nominal values and tolerances of functional parameters of railway vehicle autocoupling shock absorber units. The model parameter optimisation is achieved with respect to a minimum of fatigue damage of the vehicle load-carrying structures such that strength reliability levels of these structures does not exceed known limits and all relevant conditions ensuring serviceability of the shock absorbers are satisfied.
