The article is devoted to the issues of the synthesis of the parameters of an elastic-damping device built into the excavator’s digging mechanism to reduce dynamic loads. The determination of the parameters of this device was carried out by solving the inverse problem of dynamics using the Volterra integral equation of the second kind, which allowed linking these parameters to the nature of the transition process without finding the frequencies of natural oscillations. The transition from the differential equation of the oscillatory motion of the digging mechanism to the corresponding integral equation has been carried out, and the parameters of its resolvent and the elastic-damping device that ensure a decrease in dynamic loads are determined. The results of numerical simulation of the elastic-damping device efficiency based on the use of the characteristics of the real excavator’s digging mechanism are presented.
