Title:

METHOD FOR DESIGNING DIMPLE PATTERN OF GOLF BALL

Document Type and Number:

Japanese Patent JP2013106937

Kind Code:

A

Abstract:

To provide a golf ball 2 excellent in aerodynamic symmetry property.

The golf ball 2 has, on a surface thereof, a dimple pattern consisting of a land 10 and a large number of dimples 8. A method for designing the dimple pattern includes the steps of: (1) randomly arranging a large number of points on the surface of a virtual sphere; (2) calculating a distance between a first point and a second point which is the closest point to the first point; (3) deciding a radius on the basis of the distance; (4) assuming a circle which has a center at the first point and has the radius; and (5) assuming a dimple whose contour coincides with the circle. The dimples 8 are randomly arranged.
