Hydraulic hammer is commonly used hydraulic equipment in engineering work. The\ncharacteristics, high acceleration, high frequency and inertial working pressure,\nmake it greatly different from the working conditions of conventional hydraulic\nequipment, while hydraulic hammer for sleeve type is also not the same as other hydraulic\nhammers in structure, efficiency and working performance. Based on the\nprinciple of hydraulic hammer for sleeve type, the mathematical model of hydraulic\nhammer for sleeve type was set with various conditions in the reciprocating movement\nof piston. In addition, more detailed sketch model can be easily built with the\nmathematical model in multi-domain system analysis software, AMESim. The simulation\nsystem of breaker built based on the principle of power bond graph structures\nin AMESim system is considered comprehensively to achieve its functions and characteristics,\nwhich can quickly realize the calculation of main simulation parameters\nfor impactor. The calculated parameters can be proved to be biased with the test\nprototype. So these parameters must be optimized by Design Exploration to find the\nappropriate parameters.
