- TITLE: COMMUNICATION SYSTEM FOR STRAIN ANALYSIS OVER METALS ON THE BASE OF TENSORESISTOR TRANSDUCERS
- ABSTRACT: In this paper an architecture of a system for strain investigation and analysis over metals with remote access is proposed. The deformations of the test turners are measured by two strain gauges connected to adjacent arms of a Winston bridge. Using the data about the change of the output voltage in the measurement diagonal (Uout) of the bridge, transmitted over the LabVIEW configured serial communication channel, from NI USB 6002 module an analytical models for applied force prediction (F) were obtained by STATISTICA software. The models are examined with a high coefficient of determination R2 above level 0.98. The results according to synthesizing artificial neural networks in MATLAB environment about determination the amount of measuring transducers in detection the loads of experimental cantilever beam are presented. Two neural models with 9 and 6 hidden neurons about variables “Uout” and combination “F and Uout” with correct classification of test data were selected. Levels of the mean square error related to the synthesized neural network in two 9.9631e-04 compared to the network in one input parameter 0.0832 are observed, respectively.
