Abstract
The Optimum design of golf shaft is carried out using explicit time integration FEM analysis and mathematical programming technique. The 3 dimensional motions of the grip and the body of the player are measured using motion sensor and used to analyze the force and torque which act on the body. It is also 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 and the load to the player's body are taken as objective function to maximize. Pareto solution is also introduced to solve the double objective function.
