Research On Measurement Technology Of Rocket Thrust Line Based On The Measurement Principle Of Laser Radar

Solid rocket engine thrust line compared with the axis of the production of the deflection and will make the engine torque in work process. Thus affect the accuracy. So of solid rocket motor axis and high efficient measuring thrust line, In the production assembly and before launch of a school collect links all have very important significance.This paper discusses the present domestic rocket engine thrust line axis and measurement are studied. Put forward the current measurement method of the existing limitations. In the analysis of the current 3d coordinate measurement technology and equipment supply situation of basis, Proposed using laser radar measurement technique combining network. Completely of solid rocket motor axis and thrust line Measuring.In this paper, a general model for measuring the solid rocket motor research object, Research the Complex curved surface axis rotation, Engine reference axis weeks to zero scribed line and engine thrust line measuring method. The acquisition of laser radar three-dimensional space coordinate data for the least-square algorithm, And set up 3d coordinate transformation mathematical model of solving the space.In the analysis of practical application of laser radar measurement based on the scene, Proposed the laser radar is proposed as a measurement. Integrated into the network measurement and control platform, To solve the laser radar measurement in site meet their equipment system is huge, Self-test, calibration of the long troubled period. While the design through wireless network to realize the measurement data transmission, Thus the measurement system installation, Mobile simple and effective. In the networked control platform integration of data storage security and experts ranged support system. From the Angle of actual measurement and promotion of laser radar measurement in the work efficiency of usability, and measurement.Finally, Through the actual rocket engine thrust line axis and measurement, Verifies the paper the design of laser radar networking system possesses high practical application smeasuring and Measurement accuracy.
