Abstract

Impact devices are used in various areas of mechanical engineering and deal with a variety of materials. At the moment, it is determined that an increase in the duration of the impact impulse ensures the constant contact of a headgear (tool) with the work environment. This increases the efficiency of impact devices. We have proposed a shaper that allows to control the shape and duration of the impact impulse. In this paper, results of mathematical modeling of the pneumohydraulic impact device with elastic and viscoelastic shaper is considered. Several designs of impact devices are presented. Parameters which affect the impact impulse are determined. These results can be used in constructing pneumohydraulic impact devices for a specific area of implication.
