Abstract
In order to improve the impactor performance, the dynamic performance of gas-liquid united hydraulic hammer should be optimized. Based on the analysis of the operating principle for the hydraulic impactor, one simulation model of gas-liquid united hydraulic impactor was built with AMESim software. By setting different simulation parameters, curves of displacement, velocity, acceleration and cavity pressure were obtained under different working conditions. The key component can be obtained by the analysis of activity index. The whole simulation results provide a reliable basis for component selection and parameter optimization of hydraulic impactor.
Highlights
Hydraulic impactor is the key operating equipment of impact mechanism including hydraulic hammer [1], hydraulic rockdrill and so on
The hydraulic impactor can be classified into 3 varieties, such as full liquid, gas-liquid and nitrogen-inflating, depending by the power source driving the piston to work

Summary
Hydraulic impactor is the key operating equipment of impact mechanism including hydraulic hammer [1], hydraulic rockdrill and so on. It can directly or indirectly drive the piston reciprocating motion by the hydraulic pressure as power source. The hydraulic impactor can be classified into 3 varieties, such as full liquid, gas-liquid and nitrogen-inflating, depending by the power source driving the piston to work. Researches about the hydraulic impactor include structure design improvement, control method, computer simulation, performance test, manufacture process and basic theory [2].
