荷重測定のための力測定装置に関する。Detailed description of the invention [Industrial field of application] The object of the invention is at least one measuring element designed as a force transducer and at least one measuring element connected to the measuring element and connectable to an evaluation and display device. and one force measuring element.
The present invention relates to a force measuring device for measuring loads.

る。[Prior Art and Problems to be Solved by the Invention] Measuring forces from a small fraction of a gram to a moderate number of grams is difficult with force detectors or stroke detectors that rely on a variety of physical properties. Empirically, this type of detector is extremely sensitive and unsuitable for large forces.Therefore, to measure large forces, it is necessary to use mechanical, double or spring scales. However, in this case, of course, the accuracy decreases.
もちろん、大きい力、特に、最大数トンの力を簡単に迅
速に、かつ、正確に検知するという重大な問題がある。Of course, there is a serious problem of simply, quickly and accurately sensing large forces, especially forces of up to several tons.
本発明の目的は、このように大きい力も高精度で測定で
きる装置を創生ずることにある。An object of the present invention is to create a device that can measure such large forces with high precision.
〔課題を解決するための手段及び作用〕この目的は、冒
頭に述べた種類の力測定装置において、本発明にもとづ
き、測定部材を弾性範囲内で変形可能な部材として構成
し、測定すべき力を受けて荷重方向とは異なる方向へ力
に比例して生ずる測定部材の弾性変形が測定素子に作用
するよう、測定部材に力測定素子を結合することによっ
て、達成される。[Means and effects for solving the problem] This object is to provide a force measuring device of the type mentioned at the beginning, in which the measuring member is configured as a member that can be deformed within an elastic range, and the force to be measured is This is achieved by coupling the force-measuring element to the measuring element such that an elastic deformation of the measuring element proportional to the force in a direction different from the load direction acts on the measuring element.

が好ましい。かくして、第１に、高荷重についても、極
めて正確な力測定素子を直接に、即ち、てこ装置を中間
に設けることなく、使用することもできる。In this case, the force-measuring element is preferably coupled to the measuring element perpendicularly to the direction of the load, such that the lateral elongation or contraction of the measuring element induced by the load acts on the force-measuring element. Thus, firstly, even for high loads, highly accurate force-measuring elements can also be used directly, ie without intermediate lever devices.

となく、力の方向変更および変成を行うことができる。In the case of the object of the invention, it is preferable to use the force-proportional lateral elongation or lateral contraction in the range of elastic deformation of the material of the measuring element. By using a deformation of the measuring member perpendicular to the loading direction that is smaller than the deformation in the loading direction by a constant factor, i.e. Poisson's ratio, it is possible to redirect and transform the force without intermediate levers. .

せることができる。This force transformation depends on various parameters, in particular the dimensions of the outer bearing surface of the measuring element, the mutual spacing of the bearing surfaces or the diameter in the case of a ring shape, the geometrical dimensions of the force-measuring element, the measuring element and the force-measuring element. By selecting the elastic data of the material (elastic modulus and Poisson's ratio) and the intermediate coupling elements, it can be set virtually arbitrarily and adapted to the desired requirements.

ストも異なる力測定素子を使用して、要件に対応して精
度の異なるタイプの力測定装置を得ることができる。The advantage thus obtained is that with a single force-measuring element it is possible to create a series of force-measuring devices for diverse load spectra. Thus, it is furthermore possible to obtain force-measuring devices of different types with different accuracies depending on the requirements, for example by using force-measuring elements with different accuracies and therefore with different costs under the same load spectrum conditions.

簡単に測定できる。Another advantage of the device according to the invention is its low structural height (in the loading direction). That is, greater degrees of freedom are obtained regarding the geometrical dimensions of the device. Large forces can be measured very easily in relatively small volumes, and in some cases in high grade and expensive materials.

適である。Regarding the material selection of the measurement member, it is also preferable to use a material (for example, metal, ceramic material, etc.) whose 0-elastic Kerr transition characteristic curve changes linearly within a certain range, allowing a large degree of freedom. Particularly suitable are materials with very good spring properties (slight residual elasticity; hysteresis).

Based on the present invention, the measuring member is further configured as an elastic member that elastically curves in a direction different from the load direction in accordance with the magnitude of the load, and the above deformation acts on a force measuring element coupled to the measuring member. The device can be configured to
この場合、意図するのは、全く、測定部材の横方向伸び
または横方向縮みではなく、測定部材の弾性湾曲である
。In this case, what is intended is not a lateral elongation or lateral contraction of the measuring element at all, but an elastic curvature of the measuring element.

け面の下方に対向させて設け、力測定素子を例えば共振

ましい。In the case of a device of this type, it is preferable for at least two elastic members to be provided opposite each other below the load-receiving surface, and for the force-measuring element to be constructed, for example as a resonator, and to extend between the elastic members.
