The background of the virtual instrument is described in this article. Afterward, the composition and classification of virtual instrument are introduced, and its development trends are discussed. According to its application in mechianical vibration measurement, a typical vibration measurement system model is proposed. Last but not least, the study and research about virbration based on virtual instrument...
A virtual instrument (VI) based test method and measurement system was proposed and developed to evaluate the handle properties of textile materials such as fabrics in one step by measuring the fundamental mechanical and thermal sensory signals and simulating the psychological judgment processes during human hand evaluation process. The test method and the definition of evaluation indices for handle...
This paper focuses on introducing development and study on the measurement system of Automobile ABS tester Based on the Virtual Instrument, this paper expounds the working principles of the VI measurement system based on the LabVIEW, the hardware composition of DAQ system and the principles of compiling the control software. It instroduces a method to acquire datas by using DLL on the LabVIEW platform.
The measurement and evaluation method of human exposure to mechanical vibration is summarized firstly. A special testing system for measuring and evaluating human vibration is designed. The hardware platform is developed by assembling the sensors, the amplifier and the data acquisition etc. Based on Virtual Instrument, the signal obtained by hardware systems is analyzed by computer program. According...
