“…Hence, there is more interest in putters than in other types of clubs, with research focusing on engineering and skills [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] and also on player psychology [17][18][19][20][21].…”

The B-matrix method, which systematically analyses the dynamic response of non-symmetric rigid bodies, such as golf putters, is described. The threedimensional translational and rotational accelerations of the putter face are represented by linear equations of input forces and moments represented in matrix form. The elements of the 6 9 6 B-matrix physically represent the acceleration intensity factors. This method is applied to the analysis of the putter face control mechanism. The input forces and moments are obtained by the inverse dynamics method, whilst special attention is paid to the putter face rotation, i.e. the angular acceleration around the axis of the shaft, _ w ox : The contribution of input forces and moments on _ w ox is discussed quantitatively. The results demonstrate that _ w ox is present even if the input force and moment are applied perpendicularly to the shaft. A cancelling mechanism to correct this motion is discussed based on the Bmatrix method.

“…The number of studies on the dynamics and development guidelines of the putter itself is limited [5,22,23]. This suggests that there is a need to study putting dynamics to improve the methods for putting exercises and putter development.…”
