It conceives a new testing project of the hydraulic breaker aimed at some difficulties which lies in the performance testing of the hydraulic breaker and unique advantages of the virtual instrument,and then testing system based on virtual instrument is successfully designed.

This paper successfully designs measuring system of the hydraulic breaker is based on virtual instrument with method of gas-pressure, which is directed against the difficult points of measuring the performance of the hydraulic breaker in the light of the working principle of it At the same time, the performance measuring of the hydraulic breaker is realized.

The Study of Development Strategy of Giant Hydraulic Breaker Manufacturing Co., Ltd;

The development situation of hydraulic breaking hammer in the world is researched according to the survey and references,and the working principle of a new type of hydraulic breaking hammer is presented.
