Abstract

The invention relates to an inter-curved surface layer extrusion pressure monitoring system based on an array-type ultrathin compliant force sensor, and belongs to the technical field of precise measurement. The system comprises an array-type sensor consisting of an array-type ultrathin compliant force sensing probe and a front end circuit; a reference source; a collection module; a computer comprising an interface card and a data processing unit; and a power supply module. The power supply module is connected with the sensor and the collection module. The reference source is connected with the array-type sensing probe through line multi-route electronic simulation switches. The front end circuit is connected between the array-type sensing probe and the collection module. The interface card is connected with the row and line multi-route electronic simulation switches, respectively. The invention has the characteristics of simple structure, high antijamming capability, high accuracy of measurement, and capability of on-line monitoring of data processing in real time. The invention can monitor the extrusion pressure between face layers on line in real time.

Description

technical field [0001] The invention belongs to the technical field of precision testing, and in particular relates to a precision measuring device for extrusion force between two curved surface layers, which is used for real-time on-line monitoring of extrusion force between curved surface layers in industrial production and human medical rehabilitation process. Background technique [0002] With the advancement of science and technology and the development of production, the shapes of key parts of some major equipment have become more and more complex, and the requirements for processing and assembly positioning accuracy have become higher and higher, so the requirements for measurement are also higher. . Parts such as planes and surfaces of revolution are widely used in national defense and various daily life products, and the processing, installation, measurement and status monitoring of these parts are often restricted by special conditions such as the size of the space...
