摘要：In a method of calculating misalignment of a rotational body, radialdisplacement values are measured using a displacement gauge. A calculation partperforms the steps of deriving radial displacement amounts of the rotational body for at

least four or more measurement points along an outer surface while rotating therotational body, selecting three arbitrary points to calculate a circle, calculating circlevalues for all the measurement points, calculating differences between the calculatedcircle values and the radial displacement amounts as error amounts, summing the erroramounts to derive a total error amount, repeating circle calculation for differentcombinations and calculating a total error amount for each calculated circle, selecting acircle with a minimum total error amount as a most probable circle, and calculatingdeviation between the center of the most probable circle and the center of rotation ofthe rotational body.
