ゴルフボールの斜め衝突とスピン特性

抄録

In this paper, we simulate an oblique collision between a golf ball and an elastic body by LS-DYNA which is major FEM software. The body is used in this simulation with changing loft angle of the body, which is 15 degree, 30degree and 45degree, and also changing Young's modulus of the body. The ball is modelized by 3 piece ball, which consist of a core, a mid and a cover, and their Young's modulus are determined from our previous study. The frictional force, the normal force and the slip condition between the ball and the body are simulated by LS-DYNA. As the results, the difference of changing Young's modulus of the body and the loft angle are discussed on the frictional force, the spin rate and slip condition.
