Abstract

The topological structures of impact excitation systems in hydraulic hammers were characterized. Basic problems of reliability prediction of elements of these systems are defined. The main factors determining the reliability of working systems were identified. As an application example, the research results of small-sized hydraulic hammers are presented for which the statistical distributions of the maximum values of stresses generated in systems “beater - tool” are estimated. On this basis, the reliability prediction of impact excitation systems of these hammers was made.
