摘要： A computer (21) processes the time between ultrasonic echoes received at a transducer (19) indicative of the outer radius and wall thickness of a workpiece (10) by subtracting (69) the weighted average (80-90) wall thickness from the weighted average outer radius to generate an internal radius for a large number of points around a spiral slice of the workpiece. The internal radii and angles are converted (69) to x and y coordinates. The centroid (X, Y) of each slice of data indicating workpiece cavity internal radii is determined (71) as twice the summation of the x coordinates and twice the summation of the y coordinates of all of the datum points of the slice. The least squares fit (73) of the X coordinates of the centroids of all of the slices and the least squares fit (74) of the Y coordinates of the centroids of all of the slices are then used to determine the average axis of the cavity of the workpiece. The X^¨B7 and Y^¨B7 coordinates of the end points of the average axis of the cavity are then converted (75) to polar coordinates to permit offsetting the end points of the workpiece commensurate amounts, whereby further machining will cause the internal cavity of the workpiece to end up more nearly centrally located, on average.

摘要： Bei einem Verfahren zur Bestimmung von Lage und Größe einer Korrektur in Korrekturebenen zur Verringerung einer in einem Körper festgestellten Unwucht, bei dem bezüglich der Größe stufenweise und bezüglich der Lage kontinuierlich bestimmbare Korrekturen vorgesehen sind, wird, um eine Minimalisierung der statischen Restunwucht mit nur einem Wuchtgewicht pro Korrekturebene zu erzielen, vorgeschlagen, die vorhandene Unwucht in den Korrekturebenen nach Größe und Lage zu ermitteln, den Einfluß verschiedener mit einem Wuchtgewicht vornehmbarer Korrekturen je Korrekturebene auf die statische und die dynamische Restunwucht zu bestimmen, und diejenigen Korrekturen in den Korrekturebenen zum Wuchten vorzusehen, die der geringstmöglichen statischen Restunwucht zugeordnet sind und deren Restunwuchten pro Korrekturebene innerhalb vorgegebener Grenzen liegen.

摘要： In a tire uniformity testing apparatus which measures uniformity of a tire by measuring a load applied to the tire pressed against a rotary drum, a load estimation model is generated which is used to control a pressing position of the rotary drum, and generates a load estimation model indicating a relation between the pressing position of the tire with respect to the rotary drum and the load applied to the tire. The load estimation model is generated by: holding the tire in which uniformity has already been measured for each characteristic value; acquiring a nominal model depending on the characteristic value of the tire; and generating based on the acquired nominal model.

摘要： A tire uniformity testing apparatus (1) measures uniformity of a tire (T) by measuring a load generated on the tire (T) pressed against a rotating rotary drum (2). A load model used to control a pressing position of the rotary drum (2) and express a relation between the pressing position of the tire (T) against the rotary drum (2) and a tire load generated in the tire (T) is configured to successively measure the tire load, while changing the pressing position of the tire (T) against the rotary drum (2), and to estimate the tire load using the measured value of the measured tire load.

摘要： An imbalance correction method by which imbalance of a rotator is corrected measures the vibration state of the rotator before provisional correction and the vibration state of the rotator after the provisional correction in a plurality of rotational speeds within a determination rotational speed range in order to make vibration values within the determination rotational speed range below the standard (S1, S3). A range of set of the terminal points of correction vectors for obtaining a vibration value which satisfies a vibration standard is calculated for each of the rotational speeds from vibration vectors in the rotational speeds (S4). A definite correction vector is selected from correction vectors having the terminal points in a region in which the ranges of set calculated for each of the rotational speeds overlap one another among a plurality of the correction vectors. A definite correction amount and a definite correction phase are set on the basis of the definite correction vector (S5). The imbalance of the rotator is corrected on the basis of the definite correction amount and the definite correction phase (S6).

摘要： The present invention provides a tire balance measuring device capable of minimizing the influence exerted on a measured value due to an inclination of a lock shaft even when the lock shaft (fitted shaft) is inclined in a random direction at an angle created by a gap corresponding to a fitting allowance every time a tire is supplied with gas. The tire balance measuring device of this invention comprises a sensor for measuring the inclination of the lock shaft, and a computing unit for computing an amount of change in a unbalance of the tire from an output value received from the sensor after the tire is supplied with gas, and correcting a result of measuring a balance of the tire using the computed amount of change in the unbalance.

摘要： Embodiments relate to sensorless and continuous monitoring of electric generator rotor unbalance. An aspect includes measuring instantaneous speed of a generator rotor based on an electrical waveform from the generator. A speed flutter is extracted from the electrical waveform. The speed flutter of embodiments represents a time-based distortion of the electrical waveform. Accordingly, a magnitude of generator rotor unbalance is then quantified proportional to the speed flutter.
