In this paper, we simulate an oblique collision between a golf ball and a metal block by LS-DYNA. Two kinds of a spin ball and a distance ball are used in the simulation with changing loft angle of the block, which is 15 degree, 30 degree and 45 degree. The balls are modelized by 3 piece ball, which consists of a core, a mid and a cover, and their young's moduli are determined from compression test of the ball and the block. The frictional force, the spin rate, the shooting angle, the shooting speed of the golf ball and the slip condition between the ball and the block are examined by the simulation. As a result, the difference of the spin ball and the distance ball are discussed on the frictional force, the spin rate, the shooting angle, the shooting speed and slip condition.
