Abstract:
PROBLEM TO BE SOLVED: To provide a spring load correction method and a device therefor which can highly accurately correct a spring load. SOLUTION: This method for correcting the load so that the prescribed load is generated when the spring to be measured is at a prescribed height is provided with: a step (a) in which spring constant of the spring is obtained; a step (b) in which correction quantity of the spring is obtained using the spring constant; and a step (c) in which the spring is corrected by correction quantity of the spring. The step (b) is provided with: a step (g) in which actual height of the spring when the spring generates the prescribed load is obtained; and a step (h) in which correction quantity of the spring is obtained as height of the spring based on the actual height and the prescribed height.

Abstract:
PROBLEM TO BE SOLVED: To provide a force measuring apparatus (a dynamometer) in which an interval between a magnet and a ferromagnetic material is changed due to a load by a force (F) to be measured, especially a force measuring apparatus for a weight measurement of a seat in an automobile. SOLUTION: The force measuring apparatus 10 is provided with a receptive member 11, a rodlike member, and a measuring device 33 used to detect a displacement in a free end part of the rodlike member. The magnet 32 of the measuring device and a sensor 35 are arranged mutually in home positions, the magnet is surrounded by the ferromagnetic material, and the interval between the magnet and the ferromagnetic material is changed due to the load by the force to be measured.

Abstract:
PURPOSE:To enable independent detection of force components at a high speed, by arranging a plurality of detection means which detects the displacement of a planar elastic body at the center subject position so supported as to apply an external force evenly at the center or both ends thereof and an external force detection means. CONSTITUTION:As illustrated by (a), the planar elastic body 9c is so arranged as to be supported at both ends B and C thereof while an external force is applied at the center D thereof and strain gauges 14g, 14h, 14i and 14j are applied to detect displacements at the subject center positions on difference surfaces thereof to form a bridge circuit as illustrated. The voltage between terminals of the bridge is expressed by a specified formula to detect force alone. As illustrated by (b), the planar elastic body 9c is supported at the center D thereof while a torque F is applied at both ends B and C thereof and gauges 14g, 14h, 14i and 14j are applied to detect displacement of the planar elastic body 9c at the center D subject position of the same surface side thereof whereby a bridge circuit is built as illustrated. The voltage between terminals of the bridge is expressed by the specified formula and thus, torque about the shaft alone can be detected.
Abstract:
The invention relates to a load measuring device including a deformable component (10) configured to be deformed under a load to be measured and a sensor assembly (12) attached to a first portion of said deformable component (10) and to a method for determining load using such a sensor assembly (12). It is proposed that the sensor assembly (12) includes at least one acceleration sensor (14) configured to detect a change in an orientation of said first portion with regard to the direction of gravity (G) and that said deformable component (10) is formed as a seal (10) configured to be in sliding contact with a component (20) configured to rotate in relation to the seal (10).
Abstract:
Nonlinear spring. In one embodiment, the spring includes two opposed curved surfaces curving away from one another. A flexible cantilever member is disposed between the two opposed curved surfaces and a mass is attached to a free end of the cantilever member wherein the flexible cantilever member wraps around one of the curved surfaces as the cantilever member deflects to form a nonlinear spring. Energy harvesting devices and a load cell are also disclosed.
Abstract:
Ein mechanisches Bauteil (100) für ein Fahrzeug weist einen Messbereich (102) und ein mit dem Messbereich (102) mechanisch gekoppeltes Verformungselement (104) auf. Der Messbereich (102) erfährt bei einer im Betrieb des mechanischen Bauteils (100) auf das mechanische Bauteil (100) wirkenden Beanspruchungskraft eine Deformation. Das Verformungselement (104) ist ausgeformt, um ansprechend auf die Deformation des Messbereichs (102) eine die Deformation des Messbereichs (102) übersteigende und von einem Magnetfeldsensor (120, 122) erfassbare Verformung zu erfahren.
