Based on the virtual prototyping technology and the geological machinery design actuality, the necessity of virtual prototyping technology application in geological engineering machinery field is discussed. Furthermore, a practical strategy for setting up geological machinery virtual prototype is proposed. In order to illustrate the application future of virtual prototyping technology in geological engineering machinery, a pneumatic DTH hammer was selected as an example to be simulated and evaluated with the software PRO/E, ANSYS, and ADAMS.
