【Abstract】 The strength of drilling frame of roller drilling machine is analyzed through ANSYS software. Stress and stress distribution on the whole drilling frame and position displacement at each joint are obtained weak points of the drilling frame are found, measures to improve the stress distribution on drilling frame and to minimize the maximum deflection are put forward. The result showed that the structure has higher strength and stiffness than original scheme.更多还原
