Method for designing golf club and golf club
First Claim
1. A method for designing a golf club comprising the steps of:
- measuring a golf swing to obtain a measured result;
obtaining a swing model provided with a link model and joint torque data based on the measured result, the link model having at least two links;
performing simulation for swing the golf club using the swing model; and
obtaining head information in a specific situation during a swing based on a result of the simulation,wherein the link model includes a link corresponding to a part of a swing subject and a link corresponding to at least a part of the golf club;
a plurality of specifications of the golf club and/or the plurality of swing models are used to obtain the plurality of head information; and
stability is evaluated based on the head information,wherein the plurality of specifications of the golf club is used to obtain the plurality of head information, andwherein the stability is evaluated based on sensitivity obtained by dividing a difference between the head information by a difference between the specifications.

Abstract
A designing method of the present invention includes the steps of: measuring a golf swing to obtain a measured result; obtaining a swing model provided with a link model and joint torque data based on the measured result, the link model having at least two links; performing simulation for swing the golf club using the swing model; and obtaining head information in a specific situation during a swing based on a result of the simulation. In the designing method, a plurality of specifications of the golf club and/or the plurality of swing models are used to obtain the plurality of head information, and stability is evaluated using a difference between the head information. In the designing method, it was found that a great lateral moment of inertia of a head and a small depth of a center of gravity of the head contribute to the stability.

12. A method for designing a golf club comprising the steps of:
-
measuring a golf swing to obtain a measured result; obtaining a first swing model provided with a link model based on the measured result, the link model having at least two links; performing simulation for a first swing of a golf club with a first specification using the first swing model; measuring head information during a first swing; performing simulation for a second swing of a golf club with a second specification using the first swing model; measuring head information during a second swing; and calculating sensitivity by dividing a difference between the head information of the first swing and the second swing by a difference between the first and second specifications. - View Dependent Claims (13, 14, 15)
