| Abstract: | For the first time,compressed air expansion coefficient is introduced in the dynamic analysis of pneumatic impact equipment. On the basis of this, a theoretical calculation formula is deduced for the impact power. The maximum power is calculated and the equation between optimum expansion coefficient and pressure of compressed air is obtained which could act as guidance for design of pneumatic impact equipment. |

| Keywords: | pneumatic impact equipment Expansion coefficient of compressed air Size of matched air Impact power |
