[Abstract]:Laser vibration measuring instrument is widely used in the fields of national defense, precision mechanical manufacture, automobile and so on, so it is very important to study its calibration technology and method. The research of this subject is attached to the subproject of national important scientific instrument development project, "Measurement and reliability evaluation of three dimensional photoelectric vibration measuring instrument", which is mainly responsible for the calibration research of the key circuit performance of laser vibration measuring instrument. Including the research of calibration method, the development of standard device and the development of calibration software, a set of calibration system for key parameters of heterodyne laser vibration measuring instrument is formed. Considering the application scope of this subject, the author mainly studies the calibration of the key parameters of the processing circuit and the signal acquisition of the laser vibration measuring instrument in the range of 0.2Hz-300kHz. The main work is as follows: the first chapter describes the research background and significance of the subject, summarizes the domestic and foreign calibration research status of laser vibration measuring instrument, and summarizes the main contents of the paper. In the second chapter, six key calibration parameters are determined, such as the measurement range, linearity, sensitivity, phase shift, rise time and total harmonic distortion. The definition and calibration method of each parameter are studied. The scheme of calibrating the key parameters of laser vibration measuring instrument with electric signal is established. In the third chapter, the hardware of the calibration system of laser vibration measuring instrument is selected and designed. The design of signal generation module, data acquisition module and data processing and control module are introduced, and the whole calibration device is built using NI PXI platform. In chapter 4, the calibration system software of laser vibration measuring instrument is designed, and the software programming of user login module based on LabVIEW and the calibration module of key parameters of laser vibration measuring instrument is introduced, with the help of virtual instrument technology. The communication between the upper computer and the board card equipment and the data acquisition and processing are realized, and the automatic calibration of the key parameters of the laser vibration measuring instrument is realized. In chapter 5, the performance of the calibration system developed in this paper is verified, and the key parameters of the laser vibration measuring instrument of Shunyu Company are measured and calibrated by the calibration system, which verifies the stability and accuracy of the calibration system. The sixth chapter summarizes the full text, points out the shortcomings, and puts forward the prospects for the next work.
