摘要： A multi-component dynamometer for measuring forces and torques includes two force introduction plates and pre-oriented transducer elements without housing arranged between them. Each transucer element comprises typically a rectangular plate and two pre-oriented piezoelectric elements fixed thereon, one of these being sensitive to shear in a direction parallel to one edge of the carrier plate and the other being sensitive to pressure in a direction parallel to the normal of the carrier plate. The pre-oriented transducer elements enable the number of piezoelectric elements and electrical connections to be reduced substantially when assembling measuring platforms, as well as the amount of orientation and testing work. The platforms can be made flatter and more rigid, thereby raising the natural frequency. The electronic measuring and evaluation parts can be integrated partially or wholly into the dynamometer.

摘要： The invention concerns a sensor arrangement which is installed in the surface of carriageways or runways and serves to detect the wheel loads of vehicles or aircraft and/or their shear components on the surface during travel. The construction of the flanged tube sensor with piezoelectric crystal plates makes possible modular assembly, in that either piezo-plates sensitive to pressure P only, or to shear S, or to combinations of both are installed, since all piezo-plates have the same dimensions. The force introduction flange makes possible a concentration of the force lines onto the measuring arrangement with a substantial mechanical amplifying effect. The packing of the flanged tube sensor ready to install ensures proper fitting and positioning in the installation groove. Here the two rolling force insulation compounds and the foam insulator of the tubular part are important. The application of the invention lies in traffic management for weight detection. With the addition of shear measuring, new applications are feasible in vehicle testing tracks and aircraft landing runways, opening up new aspects of driving dynamics and security.

摘要： The invention relates to an acceleration pick-up which can be produced at favorable cost in large numbers, for which new constructional means are used. The apparatus consists of a mushroom-shaped support screw (6,56), which is inserted directly in the synthetic material housing (8) of the measuring device and which mounts and retains both the mass sensor arrangement (1, 2, 3, 4), the printed circuit board (15) as well as the housing cover (9). In the immediate vicinity of the mushroom-shaped head (7) at least one flat holding magnet (30) is likewise inserted directly in the synthetic material housing (8). In order to screen the sensor arrangement against disturbance effects, the inside of the synthetic material housing is coated with a conducting metal layer (26,28,66) for inner screening, which is connected to the screening of the connecting cable piezoelectric, piezoresistive, inductive or other systems can be used as sensor elements.

摘要： A method for calibrating a WIM (Weigh in Motion) sensor built into a road during travel of a calibrating vehicle measures the dynamic wheel force on the road and on the WIM sensor directly at the measuring wheel, depending on time or location. These wheel force data are transmitted to an evaluating unit. As the calibrating vehicle passes over, WIM signal data are simultaneously measured at the WIM sensor and transmitted to the evaluating unit. The wheel force data are synchronised with the WIM signal data in the evaluating unit. A calibration function is determined by comparing the dynamic wheel force data with the WIM signal data.

摘要： The invention comprises a force measuring system for the dynamic determination especially of axle loads, speed, vehicle wheelbase and gross weight. The force measuring system is laid permanently in the roadway. It is of modular assembly, consisting of the amplifier (11), sensor (12) and terminal module (13). The individual modules may be coupled tightly by plug-and-socket connections, welding flanges or glued flanges. The sensor module (12) consists of a hollow section (1), in which piezo-elements (4) are fitted under elastic preload. The piezo-elements (4) are accommodated in the hollow section (1) at intervals of typically 5 to 10 cm, and they may be connected all together with only one electrically conductive foil (5) to the signal processing facility (19), or groupwise or even singly. According to this subdivision the road width can be sectioned as desired, in order to obtain a road loading diagram for instance. The hollow section is designed so that it can be opened elastically by lateral clamping, to allow mechanically interconnected piezo-elements (4) to be inserted. After releasing this clamping, the piezo-elements (4) are under high elastic preload. In this way any tolerance errors can be overcome, so that costly machining operations are unnecessary and all parts with standard tolerances can be used.

摘要： A transducer insert for installing in sensors for measuring mechanical variables includes a semi-conductor body with a measuring diaphragm part of which has diffused-in strain-sensitive resistance paths or capacitor electrodes and also connecting contacts on one side. The semi-conductor body is connected to a base body of insulating material, preferably by an anodic method, through which electrically conductively coated channels pass. The channels open at a recess in the base body which is bridged by the measuring diaphragm part. The electrically conductive layers of the channels extend along the recess to the vicinity of the connecting contacts of the semi-conductor body and are directly connected thereto in an electrically conductive manner by the so-called corner drop method, e.g. by glueing, soldering or thermo-compression. A central projection can be provided in the recess of the base body which creates a deflection limit for the measuring diaphragm part. The transducer insert can be manufactured according to the so-called batch method.

摘要： A piezoresistive transduction element for incorporation into a pressure transducer includes a plate defining a diaphragm zone and preferably of silicon with piezoresistances diffused into it, an insulating plate of a glass material and a base plate. The plates are preferably connected to each other by anodic connections in a series of steps. The base plate is made of a material having substantially the same coefficient of thermal expansion as that of the material of the plate which defines the diaphragm zone. Furthermore, the dimensions of the base plate are matched to those of the diaphragm plate. By these measures the deformation forces exerted by the base plate and diaphragm plate on the insulating plate upon changes in temperature are of substantially the same magnitude and therefore there is minimum bending of the diaphragm plate. A symmetrical transduction element is created which has minimum zero point displacement and minimum sensitivity changes in use. Pressure transducers equipped with such piezoresistive transduction elements are therefore appropriate for high measuring accuracy, particularly in combination with an improved, elastically extensible securement of a holder which carries the transduction element within the transducer housing.

摘要： The detector arrangement comprises a measuring rail with a number of individual elements each having a sensor mounted on a bottom rail and include rectangular elements as force introduction flanges, whose length in the direction of travel is a multiple of their width in the axial direction of the rail. The measuring rail is part of a measuring arrangement for detecting the tire pressures of vehicles in motion. The arrangement includes also at least one contact rail placed ahead of the measuring rail in the direction of travel, and a data acquisition facility. The vehicle speed is determined with the help of the contact rail. The measured values from the sensors yield a tire contact surface with an isobar pattern. From these two, the data acquisition can determine underinflation, normal pressure and overinflation of the individual wheels besides axle loads and vehicle weights, whereby underinflation and overinflation at least are displayed as faults.
