Zur
Messung von Dehnungen an Bauteilen werden üblicherweise Dehnungsmessstreifen
(DMS) als Sensoren eingesetzt. Die DMS (
Werden
die unter mechanischer Beanspruchung hervorgerufenen Dehnungen an
bestimmten Bereichen eines Bauteils als Messwert benötigt, um z.B.
Biege- oder Torsionsspannungen zu ermitteln, so müssen die
DMS direkt am interessierenden Bereich des Bauteils appliziert werden.
Ist dabei eine kabelgebundene Ankopplung des DMS mit einem Signalverarbeitungsgerät nicht
möglich
oder unerwünscht,
wie z.B. bei der Applikation an rotierenden Bauteilen oder an Implantaten,
kann diese durch eine Funkverbindung (
Die
zur Signalverarbeitung und -übertragung erforderliche
Telemetrieelektronik (
Zudem kann eine Funktionsprüfung des Systems erst nach endgültiger Applikation vorgenommen werden. Handelt es sich bei dem zu vermessenden Bauteil um ein z.B. teures Bauteil (z.B. Implantat für die Knochenbruchbehandlung), so wäre eine vorgeschaltete Funktionsprüfung des Messsystems vor Applikation am Bauteil wünschenswert, um einen möglichen kostenintensiven Ausschuss bei Nicht-Funktion zu vermeiden.moreover can be a functional test of the system only after definitive Application be made. Is it the one to be measured Component around a e.g. expensive component (e.g., implant for bone fracture treatment), that would be an upstream functional test of the measuring system before application on the component desirable to a possible to avoid costly rejects in case of non-function.
Aufgabenstellungtask
Der
Erfindung liegt Aufgabe zugrunde, die Herstellung von Dehnungs-Messsystemen
zur Anwendung an nicht optimal zugänglichen Stellen zu vereinfachen
sowie die Anwendung von Dehnungsmessstreifen durch Vermeidung von
nach dem Aufkleben anzulötenden
und in der Regel empfindlichen Kabeln (
Die
Aufgabe wird durch die Merkmale der Patentansprüche gelöst. Die angegebene Lösung besteht
darin, dass im Gegensatz zum bisherigen Anwendungsverfahren die
Dehnungsmessstreifen (

Das
hier beschriebene telemetrische Sensormodul (
Der DMS sollte hierbei möglichst nahe der oder direkt an der Oberfläche des Moduls, die später am Bauteil angebracht wird, flächig angeordnet sein.Of the DMS should be as possible near or directly on the surface of the module, which later on the component is attached, flat be arranged.
Die
Telemetrieelektronik (
Als
Verkapselungsmaterial können
z.B. Kunststoffe (z.B. Epoxid) verwendet werden, mit denen der mit
der Elektronik verbundene Dehnungsmessstreifen zu einem Modul (

Weitere Anwendungen sind denkbar an aus verschieden Gründen schlecht zugänglichen Bauteilen, z.B. in Maschinen oder Fahrzeugen. Auch hier erfordert die Applikation von Dehnungsmessstreifen und das anschließende Anlöten der Kabel hohen Aufwand, welcher durch das vorgefertigte Modul verringert werden kann.Further Applications are conceivable for various reasons difficult to access Components, e.g. in machines or vehicles. Again required the application of strain gauges and the subsequent soldering of the Cable high effort, which is reduced by the prefabricated module can be.
Eine
hochgradige Miniaturisierung des Systems ist technisch möglich und
ebenfalls vorteilhaft. Durch Kombination der Dehnungsmessstreifen
mit einer Subminiaturelektronik und Antenne auf einem Träger (
