The possibility of improving the durability of spherical sliding hinges due to the strengthening of the incomplete spherical surface of ball fingers by static-pulse processing is considered. The review of recent researches and publications was carried out and promising directions for increasing the durability of ball joints were established. The influence of the shock system parameters on the shape and amplitude of the impact pulse is analyzed. The recommended range of correlations of the geometric parameters of the elements of the shock system is established. On the basis of theoretical and experimental studies, a model of shock system with static load of the boom and tool, as well as a bipolar shock treatment scheme is proposed. The method of calculating the parameters of the shock system and the mathematical dependences have been developed. The model of the mechanical impulse generator of shock impact machine with static load of the boom and the tool according to the bipolar impact processing scheme is proposed. The method and algorithm of calculation of parameters of the generator of mechanical impulses of the device for strengthening of incomplete spherical surfaces is developed.
