基于CAN总线的风洞试验模型电动舵机系统

摘要

Aiming at the model of rudder angle in wind tunnel tests need to repeat change, an electric actuator system based on CAN bus for model in wind tunnel test was proposed. Introduced the structure and the working principle of electric actuator, the model rudderand and the elevator motor actuator was developed. Then conventional load test and repeat test of wind tunnel were conducted with the D600 model. Results show that the system can realize the auto-control of the control plane in wind tunnel test, the precision of the test can meet all of the qualified indicators and part excellent indicators of the GJB. In a word, this digital servo system has good reliability, good accuracy and high control precision.%针对风洞试验中模型舵面角度需要重复改变的问题，介绍一种基于CAN总线的风洞试验模型电动舵机系统。介绍电动舵机系统的组成、工作原理，开发模型方向舵和升降舵电机舵机系统，并采用 D600模型进行风洞常规测力试验、重复性试验。结果表明：该系统能实现风洞试验中模型舵面的自动控制，试验精准度均能达到国军标合格指标和部分达到先进指标，具有较好的可靠性、准确性及控制精度。
