An testing method and principle for air impactor with position sensor is introduced. A simular rock device is designed. The piston displacement of test simulation device is tested with position sensor and collected with the SCM system. Corresponding function between impact energy and displacement is found, and used to test the impact energy of DTH impactor. The method is high efficiency in comparison with the traditional test methods. It can quantitative testing and automatic record, and applies to industrial test, then improve the product quality management level.
