Popis: This paper investigates the dynamics of a pneumatic dot peen marker without a slide valve. Dot peen marking is a promising method of marking part at any stage of the manufacturing process. A mathematical model of the marker is proposed, where vibration and impact properties of the system were described using methods of stereo-mechanical impact theory; the loads were calculated by solving a coupled gas dynamics problem. The design model is comprised of a nonlinear oscillator having one degree of freedom. The problem was solved using numerical integration. The proposed approach allows to describe major characteristics of dot peen marker operation, such as boundaries of the effective self-excited mode, amplitude and frequency of peen oscillation, pressure and temperature in the working chamber. The influence of the marker’s characteristics on the operating parameters was investigated using the calculated time histories of the state vector elements.
