| Abstract: | A new evaluation method used for position/orientation offsets of the universal joints is developed here. The angle between inputting axle and outputting axle of the joints is defined to be independently variable, and is introduced into direction cosine matrix. The spectral norm of direction cosine matrix is made to be the evaluation value which is used for evaluating position/orientation offsets of the universal joints. The method is emulated by MATLAB and the varying range of the evaluation value is calculated. |
