To assure the metrological traceability of a measurement, it is required to perform an analysis of the measurement uncertainty specific to the measurement task. An approach to estimate the measurement uncertainty for complex systems is the so-called virtual measuring instrument: The measuring process is simulated taking into account its influencing parameters and a statistical analysis is performed by means of Monte-Carlo calculations. We present the development of such a virtual measuring instrument for scanning electron microscopy (SEM) which allows to estimate the measurement uncertainty in

Abstract:

The paper presents the results obtained by investigating some functional parameters as the noise level, the pressure – drop and the temperatures of three different manufacturing solutions for mufflers. The results emphasize the corroboration between these parameters and contribute to the improvement of the muffler fabrication and design since it is a complex function that affects noise characteristics, emission and fuel efficiency of engine. It was designed a measurement chain for the noise level evaluation of the mufflers including a microphone Bruel&Kjaer type 4133, a Impulse Precision S

This paper introduced an electrical measurement system based on virtual instrument theory. This system uses the design method of component object model (COM) , which makes the software serviced and updated very easily. This system also uses the Access database, introducing the idea of "real-time measuring savings". The whole system doesnt increase much cost, simplify the measuring process and improve the efficiency, achieves the anticipated aims very well.

Abstract:

AbstractValidity and correctness test verification of the measuring software has been a thorny issue hindering the development of Gear Measuring Instrument (GMI). The main reason is that the software itself is difficult to separate from the rest of the measurement system for independent evaluation. This paper presents a Virtual Gear Measuring Instrument (VGMI) to independently validate the measuring software. The triangular patch model with accurately controlled precision was taken as the virtual workpiece and a universal collision detection model was established. The whole process simulation

Abstract:

Elastic modulus is one of the most important performance parameters of wood-based material, and plays an important role for predicting and evaluating quality of wood-based material. At present, the traditional problems for measuring elastic modulus of wood-based material are: expensive testing instrument, short precision, low immunity to noise and less ease to connect. This paper presents a new elastic modulus-measuring system based on virtual instrument. The system ensures the following functions: (1) real-time data acquisition, (2) signal processing and analyze, (3) saving the file in the ap

Abstract:

During quantitative analysis on measured object by using equal precision measurement method, there remains certain difference between the measuring result and truth value due to the impact on measuring method, measuring tools and measuring environment. In order to reduce measurement error, we usually make continuous equal precision measurements on the measured object repeatedly. Then we get the final result by theoretical calculations, error analysis and dispose on measurement data. The data processing shows complicated and error-prone .But now we take computer as a carrier, then combining wit
