| PURPOSE:To calculate highly accurate moment of inertia easily in a short time by calculating the moment of inertia based on transmissivity (density of a photograph) of radiation of an object to be detected. CONSTITUTION:First, an X-ray photograph of a power unit 1 is taken from a Z axial direction with an X-ray camera. At this time, calibration data (reference data) 3 formed with the same material as the power unit 1 such as differs in stages according to the transmission length from the transmissivity of the X-rays are photographed at the same time. In the X-ray photograph of the calibration data 3, the density distribution can be known from the X-ray photograph density (transmissivity). The center of gravity of the power unit 1 is calculated with a computer and the coordinate transformation is made with the center of gravity as the new origin to calculate the moment of inertia. | ||||||

Stabilizators 8 and 8' and bearing stoppers 7 and 7' are provided in upper and lower ends of the rotating cylinder 5 to permit the rotating cylinder 5 to turn only in the rotation direction. In case that a moment of inertia is measured by a measuring device constituted in this manner, an object having a known moment of inertia is set on the supporting table 6, and the period of the rotative oscillation of the rotating cylinder 5, and a coefficient of torsional rigidity of the wire 2 is determined, and thereafter, this coefficient is used to the moment of inertia of an optional object to be measured. | ||||||

The data stored in the storage units 105 and 106 are subjected to operation processing in an inertia moment operating unit 107, and thereby directional axes are calculated. | ||||||

| <P>PROBLEM TO BE SOLVED: To easily and properly determine a position of a center hole of a crankshaft. <P>SOLUTION: A center hole determination method determines the center hole of a material crankshaft formed by molding with a cope and a drag, and includes first to fourth steps. In the first step, shape data of each part molded with the cope and drag is obtained. In the second step, measurement data of each part is compared with the corresponding design data to calculate a mismatch amount caused by mismatch of each part.

| PURPOSE:To execute a measurement with much higher accuracy than before, and also to improve remarkably the efficiency for measurement by providing a motor for rotating an object to be measured, and a means for measuring a time when this motor reaches a prescribed revolving speed. CONSTITUTION:An object to be measured 4 is placed on a motor 5 so that the rotation of the motor 5 is detected by a frequency generator 6, and its output frequency is converted to voltage by an F/V converter 7. When the motor 5 reaches some revolving speed and the frequency of the frequency generator 6 is F/V-converted, and when a time when its voltage becomes equal to voltage of a reference power source 8 is denoted by tx, in that case, an output of a comparator 9 is changed to ''Lo''. That is to say, no current flows to a constant-torque driving device 11. Therefore, basing on this time, this device measures the inertia moment of the object to be measured, and accordingly, the inertia moment can be measured with much higher accuracy than before. | ||||||

| PURPOSE:To measure easily the moment of inertia of an object to be measured by subjecting a horizontal arm of known moment of inertia attached with an object to be measured to free damped oscillation by means of a spring having a known spring constant, and measuring the oscillation frequency thereof. CONSTITUTION:An arm 6 attached with an object A to be measured is turned against a spiral 10 to bring an iron piece 11 opposite to a solenoid 12 for starting. When the operator pushes a start switch 14 of a box 13 of a display device, a solenoid 12 is de-energized, and the arm 6 including the object A performs free damped oscillation. Therefore, a photocoupler 16 detects the pass time of a light shielding plate 15, that is, the oscillation frequency of the arm 6. Said oscillation frequency time is inputted to the box 13, where the result calculated by the microcomputer built therein is displayed directly as the moment of inertia of the object A with a display device 17 of the box 13. The moment of inertia of the implement is thus easily measured as a rational measure for selecting the implement. | ||||||

| Systems and methods for estimating an inertia, a Coulomb friction coefficient, and a viscous friction coefficient for a controlled mechanical system are provided. In one or more embodiments, an inertia and friction estimation system can generate a torque command signal that varies continuously over time during a testing sequence. The velocity of a motion system in response to the time-varying torque command signal is measured and recorded during the testing sequence. The estimation system then estimates the inertia and the friction coefficients of the motion system based on the torque command data sent to the motion system and the measured velocity data. In some embodiments, the estimation system estimates the inertia and the friction coefficients based on integrals of the torque command data and the velocity data. | ||||||

| A torque command value and an acceleration detection value are accumulated when a driven portion is subjected to acceleration/deceleration driving, and, from a ratio between the two, inertia of a movable portion is calculated. By executing the acceleration/deceleration driving about a position where influence of gravity torque is zero, the influence of the gravity torque included in the torque command value before and after the center position is offset, whereby inertia can be estimated correctly even with a machine structure in which the influence of gravity differs depending on the position of the motor. | ||||||
| 80 | Method and apparatus for producing balanced drumstick pairs | US14189445 | 2014-02-25 | US09626943B1 | 2017-04-18 | David James Hughlett |
| One or more drumsticks may be optimally balanced using a grip point of the drumstick by calculating a radius of gyration. The radius of gyration is a controlling parameter wherein the radius of gyration correlates with the grip point, which is itself based on a particular gripping style and hand size. Given the radius of gyration, the center of gravity of the one or more drumsticks may be re-located at a point along the drumstick closely aligned to the radius of gyration. The re-location may be performed by adding a weight to the butt end of the drumstick. Balanced drumstick pairs provide optimum performance, control and handling characteristics for a drummer. | ||||||
