Abstract
The Optimum design of golf shaft is carried out using explicit time integration FEM analysis and mathematical programming technique. The 3 dimensional motion of the grip is measured using motion sensor and used for the input of FEM, and shaft is divided into several segment, and bending rigidity and torsional rigidity of each segment is taken to be the design variables. The speed of club head is taken as objective function to maximize. Legendre function is used to solve the discontinuity of the optimal solution. Parreto solution is also introduced to solve the double objective function.
