Research of Shape Measurement and Control System for Fast Reactor Assembly Based on Virtual Instrument Technology

Using virtual instrument technology, a shape dimension measurement and control system is designed for the assembly shape and size measurementsin the experimental thermal shock tests of the shielding layer assembly and the reflective layer assembly of Chinese Experimental Fast Reactor. The hardware of the system is realized using NI's data acquisition cards,on which the software is developed using the Labview platform. The system with control, measurement, and data processing functions, can accomplish the shape and size measurements, i. e. the eccentricity, twist, and bend degree of assembly of fast reactor. Experiments show that the system achieves the design goals of stability,accurate measurement full function,and sefety in operation.
