| 161 | METHOD OF ESTIMATING LOAD INERTIA FOR A MOTOR | US11565031 | 2006-11-30 | US20070143040A1 | 2007-06-21 | Yuuji Ide |
| A method of estimating load inertia for a motor is provided that can estimate the load inertia even when a cogging torque of the motor is large or resonance occurs in the mechanical system of the load. Vibration is detected in an acceleration feedback signal. An estimated inertia gain Kn is multiplied by a coefficient α of zero (0) or more but less than one (1) when the detected vibration is equal to or more than a predetermined level, or the estimated inertia gain Kn is multiplied by a coefficient α of one (1) when the detected vibration is less than the predetermined level. | ||||||

| The weight, balance point and swing weight of a sports implement such as a tennis racket can be automatically duplicated using a measuring unit and a computer program that uses data supplied by the measuring unit and data prestored in a database. The measuring unit measures the total weight of a raw tennis racket, the force it exerts when supported by the balance and a fixed point, and the period of oscillation of the tennis racket when swung as a pendulum. The computer calculates the weight of a molded handle to be formed on the raw racket and the weight and location of lead weights to be added to a finished racket made from the raw racket so that the finished racket meets the specifications prestored in the computer. The system thus enables a particular racket to be duplicated by matching the properties of the finished racket with prestored specifications of the particular racket. | ||||||
| 163 | Method for determining the moment of inertia | US535845 | 1995-09-28 | US5656768A | 1997-08-12 | Georg Abler; Johann Eitzinger; Klaus-Christoph Harms |
| For largely automatic determination of the moment of inertia of, in particular, an internal combustion engine on a testing stand, speed n and indicated torque M.sub.M are measured under controlled operating conditions in both a run-up phase as well as in a coasting phase. In order to eliminate the loss moment in the determination of the moment of inertia, the measuring points of the respectively same speed from the run-up phase and the coasting phase are interpreted in combination, this enabling an exact determination of the moment of inertia in a very simple way with the devices that are usually already present at a testing stand. | ||||||
| 164 | Vehicle inertia and center of gravity estimator | US536389 | 1990-06-11 | US5136513A | 1992-08-04 | David Sol; Shunso F. Watanabe |
| A vehicle inertia and center of gravity estimator uses averaged displacement measurements to estimate changes in vehicle body mass, vehicle center of gravity location, and vehicle pitch moment of inertia, due to variations in fuel load, passenger load, and cargo load. The system is responsive to the acceleration of the vehicle for providing displacement readings, the mass of the vehicle, and the rotation of the vehicle to optimally adjust vehicle parameters. Variables used in estimating vehicle conditions include vehicle vertical displacement, vehicle ride height, vehicle mass, vehicle pitch moment of inertia, vehicle center of gravity location, and vehicle wheel base. | ||||||

| An apparatus for measuring moment of inertia incorporating a torsional pendulum and an analog electronic circuit. The circuit measures the period of oscillation, sets a scaling factor equal to the torsional coefficient of the resilient member, and computes moment of inertia by multiplying the scaling factor by the square of the period of oscillation. The moment of inertia is then displayed in metric units. | ||||||

| 167 | Mass properties measurement system | US887606 | 1978-03-17 | US4161876A | 1979-07-24 | David A. Carpenter |
| The mass properties measurement apparatus of this invention includes a pair of opposed bearing assemblies, each comprising a fixed bearing and a movable journal, and a radially rigid connection between the movable journals located on an axis with a single degree of freedom, which is rotation. A test object support table is fixed to one journal for rotational movement therewith, the plane of the surface of the support table being perpendicular to the rotational axis. A torsion wire coincident with the rotational axis is fixed at one end to the one journal for rotation with the support table and is fixed at its other end against rotation with the support table, thereby creating a torsional pendulum which permits oscillatory movement of the support table. Means are provided for measuring successive oscillation periods of the support table for determining the center of gravity and principal axis moments of inertia of a test object on the support table. Finally, a fail-safe caging mechanism is provided. This device engages the shaft under controlled conditions if gas pressure falls below acceptable values thus protecting the bearing surfaces from damage and providing an orderly shutdown. | ||||||
| 168 | Stamping or nibbling machine having a workpiece feed operable in accordance with the weight and center of gravity of the workpiece | US710370 | 1976-08-02 | US4089244A | 1978-05-16 | Eugen Herb; Hubert Bitzel |
| A stamping or nibbling machine, comprises a workpiece support or means for engaging the workpiece at a spaced location from a punch which reciprocates upwardly and downwardly in respect to a die in order to effect the stamping or nibbling of the workpiece. The support is mounted on a transverse bar which is pivotable about a transverse guide and the guide is carried on a carriage which is pivotable about a longitudinal guide. The workpiece is fed by holding the bar and the carriage against pivotal movement and driving them in the respective longitudinal direction when the punch is lifted off the workpiece. The rate of this feed may be controlled in timed relationship to the movement of the punch so that the feed takes place when the punch is off the workpiece and in a speed of feed which is determined in accordance with the torque acting on the transverse bar and the carriage when they are released for pivotal movement and sensed by associated torque meters. In addition, the feeding control is also carried out in dependence upon the weight of the workpiece as measured, for example, by a measuring bolt at the location of the die. The stamping stroke of the punch can be released through a time-delay device which is controllable by the measuring device for determining the weight of the plate. The torque meters effect a measurement of the center of gravity of the workpiece at any time during its positioning in respect to the punch and the die. | ||||||

| The present vibratory apparatus for determining the mass moment of inertia of bodies has two plates which are vibratable and interconnected by a spring arrangement having at least two spring elements traversing each other in the oscillating axis of the apparatus.

| A set of golf clubs is provided which is balanced on the principle of common ''''moment of inertia'''' as opposed to the prior art sets which are balanced on the principle of common ''''moment of weight.'''' The moment inertia about a given axis of any club in the set is no more than 5 percent, preferably 2 percent, particularly 1 percent greater than that of the club having the lowest moment of inertia in the set. Usually the said axis is one which passes horizontally through the top end of the shaft.

| A dynamically matched set of golf clubs having identical moments of inertia with respect to a common swinging axis and, starting with a selected favored club, the method of determining by calculation from simple length and weight parameters, the head weights required for dynamically matching the other clubs of the set to the favored club.

| The invention relates to a device for determining the inertial parameters of a body, particularly a motor vehicle. Said device comprises a receiving platform (P) on which the body (F10) can be placed. The receiving platform (P) is provided with a central, especially spherical joint (G00) about which the receiving platform (P) can be moved with three degrees of freedom (x, y, z) by means of drive units (Z1, Z2, Z3). The invention further relates to a method for determining the inertial parameters of a body, particularly by means of a device disclosed in one of the preceding claims. In said method, a control system is provided which allows a receiving platform (P) and a body (F10) mounted thereon to be moved about a central pivot (G00) with three degrees of freedom (x, y, z). The forces measured in the joints (G00, G20) and the angles measured in the central joint (G00) are fed to an evaluation process, by means of which the inertial parameters of the body (F10) are determined especially by using laws of mechanics, particularly the principle of angular momentum. | ||||||
