Life Testing System For The Liquid Integral Gyro

With the development of aviation and aerospace technology, navigation system of aircraft is more and more precise and complex. So the reliable life of navigation system is more and more concerned. Gyro belongs to a complicated electromechanical system which reliable life not only involves electronics, but also refers to mechanics. For heightening reliability of weapon system and spacecraft, degrading the operating risk, the relative requirements need reliability life of the gyro definitely. It is very important that improve the reliability parameters life of the gyro.For the above issues, In this paper, through inspection a large number of relevant literature on the basis of the gyroscope reliable life both at home and abroad and have done much the relevant theoretical analysis. As a guide to theory, design the life test system of a certain type of the liquid integral gyro. The pilot system is divided into system hardware and database analysis software in two parts. The main parameters of the test pilot system can be divided into two parts: auxiliary section of the test and signal conditioning and control part. System can be tested on the gyroscope to conduct a comprehensive parameter detection,performance analysis,life expectancy analysis,fault diagnosis,data storage and query operations, and testing the accuracy gyro state parameters. Equipment can be long-term, continuous unattended work with a variety of fault mode automatic diagnostic capability, complete life test data acquisition, display, interpretation, communication, storage, management, and other functions, should be in accordance with abnormal fault type automatic processing to ensure that the gyroscope security.Finally, We have Carried on the testing and reconcile of the system and obtained test results and preliminary test results. The fluid floated the top length-of-life test system to complete basically has floated the speed integrating gyroscope movement condition to the fluid the on-line monitor and the real-time display function. Thus has supplemented the brand-new content and the method for the domestic related profession standard's further consummation and the science objective appraisal, For a more comprehensive understanding and the analysis influence gyroscope reliable life factor, to further develop the high performance gyroscope to lay the foundation.
