State-of-the art design methods for the rail-wheel system of stacker cranes do not
use realistic load collectives. Therefore, these design methods regularly lead to
inaccurate results. The BS EN 13001-3-3 addresses this issue by introducing a more
realistic load collective, represented by the contact force spectrum parameter, which
considers the rail-wheel contact forces of stacker cranes’ entire life cycles. However,
due to its complexity the contact force spectrum parameter is difficult to compute
in practice. This paper introduces a simulation model for the computation of the contact
force spectrum parameter. Moreover, it is shown that by simulating a limited number
of stacker cranes’ working cycles, a representative result is obtained. Hence, with
the results of this paper it is possible to compute a realistic load collective with
the purpose of designing the rail-wheel systems of stacker cranes accordingly.
