| Abstract: | A mechanical model is developed on the bases of the quasi-static process in a thermal system and the fluid continuity equation,with a sectioned function derived for the pressure change process in air chamber.The point-transformation method available to describe the periodic physical phenomena is used to derive and sole a successor function of the stroke of pneumatic vibrator in relation with impact energy.Furthermore,the self-excited vibrating process of pneumatic vibrator is discussed utilizing a phase plane diagram. |

| Keywords: | pneumatic vibrator point-transformation method phase plane diagram successor function limit circle. |
