【Abstract】 The cylinder is an important part of percussive hammer. Because of its complex working environment and force, it is very difficult to use the general methods in analyzing its strength exactly. Finite element method is an effective mathematical calculating method. Through applying ANSYS software, and building the mathematic model of the cylinder of YSC-178 Fluid Efflux Hammer, stress and strain of the cylinder in different working condition were analyzed. At last, the conclusion that the deformation of cylinder happens primarily in radial orientation, comes out, which is consistent with real result. It apperars to be that using finite element method is very accurate and reliable to analyze every parts of drilling tools,and can be used in guiding and optimizing design.更多还原
