Golf club face thickness optimization method
A method of optimizing golf club head and golf ball design is disclosed herein. The method includes inputting a RBF for stress, a RBF for CT and a RBF for ball speed into an Adaptive Simulated Annealing algorithm to generate an optimized structure for the club head for ball speed.
1. A non-transitory computer readable medium storing instructions that optimize a structure of a golf club head for ball speed, when executed by a processor, cause the processor to:
generate a plurality of face thickness points and a plurality of body thickness points using a sampling technique to fill a design space using a finite element analysis (“FEA”) program to generate a plurality of responses comprising a plurality of performance characteristics for the golf club head;
generate a surrogate model from the plurality of responses comprising
generating a function for durability of the golf club head from a finite element analysis (“FEA”) program of the golf club head using the plurality of face thickness points for the golf club head and the plurality of body thickness points for the golf club head;
generating a function for ball speed of a golf club head from the FEA program using the plurality of face thickness points for the golf club head and the plurality of body thickness points for the golf club head;
use the surrogate model in an optimization algorithm to provide an approximation of a lower sample space; and
repeat the above mentioned steps until the surrogate model converges with the FEA for a predetermined objective to optimize the structure of a golf club head for ball speed.
2. The non-transitory computer readable medium according to claim 1 wherein use the surrogate model in an optimization algorithm to provide an approximation of a lower sample space comprises inputting a constrained function for durability and the function for ball speed into a meta-modeled based optimization algorithm to generate an optimized structure for the club head for ball speed.
