Design of 2MN thrust measurement auto-calibration system

Fu Zheng (Xi'an Aerospace Propulsion Test Technique Institute,Xi'an 710100,China)  
The 2MN thrust measurement auto-calibration system,using hydraulic pressure sources to produce stable standard force,using servo-controller to measure the output value of the standard force sensor,then making the sensor output value equal to the standard force,can realize the high precision control of force. During the calibration process,the fore-and-aft end computers communicating by serial port with the handshake protocol set according to the character of work pro-cess,the system judges the intercommunion signal,then determine the status of the calibration pro-cess automatically,and make correlative disposal. This system can realize the automation of calibra-tion process,and ensure the integrility and the veracity of the calibration data.
