Study On The Spot Measure Multi-Parameters Analyzer

Experiments must to be calibrated before a test is gong to be processing, especially a large test, with the test request of the military industry technique improving and the control of measure process to have been written in. So manufacturer is in dire need of the ability for simultaneous measuring many parameters, in order to calibration test at any moment. The Spot Measure Multi-Parameters Analyzer was developed for the request. Spot Measure Multi-Parameters Analyzer can measure force, pressure, temperature, vibration (contain the acceleration and frequency), twist 6 measure parameters at the location of producing and testing by virtual instrument design project. This item is emphases scientific research item of the military metrology of the national defense "15".The text introduces the Spot Measure Multi-Parameters Analyzer's the design project, the hardware and software of developmental process. After the development of Spot Measure Multi-Parameters Analyzer was finished, every parameter's uncertainty of measurement was amply analyzed. It was proved that all main specifications of the Analyzer fulfilled or surpassed the design criterion, after measuring, testing, and computing for 4 months. At last, it obtained nicer effect that the puller, twister, vibrator were calibrated in the manufacturing spot and whole missile's vibration was tested, with the Spot Measure Multi-Parameters Analyzer.It can be researched of 5 conclusions by investigating the item:(1) The Spot Measure Multi-Parameters Analyzer was devised successfully, include force, pressure, temperature, vibration (contain the acceleration and frequency), twist 6 parameters by making use of virtual instrument design thought. (2) It is proved by analyzing the uncertainty of measurement of Spot Measure Multi-Parameters Analyzer's force, pressure, temperature, vibration (contain the acceleration and frequency), twist 6 parameters, that force specifications' uncertainty of measurement is 0.1%; Pressure specifications' is 0.2%; The lower temperature specifications' is±1.5℃; The higher temperature specifications' is 0.3%; Frequency specifications' is±0.04Hz when frequency is less than 100Hz; Frequency specifications' is 0.05% when frequency is more than 100Hz; Acceleration specifications' is 4.2%; Twist specifications' is 0.2%. (3) It is proved that the repeatability of all parameters is less than 2/3 of the complex...
