Non Destructive

An imaging system of ultrasonic detection is presented for non-destructive testing (NDT) of complex structures by using virtual instrument technology. The control devices for C-scan as well as for imaging system are designed and manufactured. In the coarse scan mode with the scan step of 1 mm, the system can quickly give an image display of a cross section of 80 mm (L) ×60 mm (D) by one measurement. In the refined scan model, the system can show a refine image of the coin. All experiments on coin, bulk metal, and other forms of specimen verify the efficiency of the proposed method. The experimental results are accurate and reliable.

Dynamic Resonance

Characteristic parameters of piezoelectric ceramic have immeasurable effects on its performance. On the basis of the equivalent circuit of piezoelectric ceramic, dynamic resonance method is used to measure a series of cylindrical piezoelectric coefficients. Based on labview virtual instrument technology, an automatic measurement system with Agilent E4980A impedance analyzer is developed. The characteristics of impedance frequency response are recorded and the admittance circle is drawn. Then the major parameters including d33 are measured automatically and the reports are generated. Finally, E-S(Electric-Strain) method is adopted to verify the reliability of the measurement results. The results showed that the dynamic resonance method had good repeatability with the standard deviation no more than 1.66%, and the test values were in accord with the E-S method.

With the popularization of network technology, the computer technology is developing rapidly coupled with the emergence of virtual instrument technology. In this context, virtual experiment, an effective complement to the development of the traditional experimental method, has very broad spectrum of application in the field of education, measurement, and even other research areas. Thus, virtual experiment has become an important future development of experimental teaching. Based on analysis of the history and current status of the existing virtual laboratory at home and abroad, as well as the technologies used to accomplish a virtual experiment, this thesis makes a comprehensive study to analyze the construction of the virtual experiment system, including the basic theory of its establishment, the network environment, application classification, the specific tectonic model and technical methods and its development and applications.
