Patent ID: 8894510

Claim:
A method for defining a golf ball dimple surface, the method comprising: providing a response of an under damped harmonic oscillator, wherein the response has an envelope of oscillation, OE, described by OE ⁡ ( t ) = ± X ⁢ ⁢ ⅇ - ζω n ⁢ t , ⁢ where ζ = c 4 ⁢ mk , ⁢ ω n = k m , ⁢ X = [ ( x 0 ⁢ ω d ) 2 + ( v 0 + ζω n ⁢ x 0 ) 2 ] 1 / 2 ω d , ⁢ ω d = ω n ⁢ 1 - ζ 2 , and where t is observation time, v is velocity, m is mass, k is the spring constant, c is the viscous damping coefficient; defining a golf ball dimple profile based on the envelope of oscillation where the observation time is equal to one half of the dimple diameter; and rotating the dimple profile 360° about a vertical axis to define the dimple surface.
