用于捕获轨迹风洞试验的三自由度转角头设计

The design of a 3-DOF robot arm used forcaptive trajectory simulation in wind tunnel test

  • 摘要: 设计了用于FL-12风洞捕获轨迹试验的三自由度转角头装置,该装置为机电一体化设备。介绍了三自由度转角头装置的结构设计,控制系统设计,驱动元件的选型计算及校核,并对装置进行了静力学与动力学分析以验证设计结果。结果表明,和现有装置相比,该三自由度转角头在俯仰和偏航方向的载荷能力均由100N·m提升至250N·m,可控制精度由0.1°提升至0.05°,在滚转方向的载荷能力由10N·m提升至20N·m,可控制精度由0.1°提升至0.05°。通过对试验装置风洞适用性的研究,在设计中对驱动元件及线缆的结构、整流装置的外形、装置总体尺寸等进行了优化,改善了现有设备线缆外露,外形整流性能较差以及风洞堵塞比较大等问题。

     

    Abstract: A 3-DOF robot arm design is presented for the Captive Trajectory Simulation (CTS) test in the FL-12 wind tunnel. It is an integrated mechatronics device. The paper introduces its transmission principle design, physical design, control system design, drive element selection calculation and verification, then verifies the design results with dynamical and static mechanics analysis. The results show that the device improves the load in pitch and yaw from 100Nm to 250Nm with control precision from 0.1°to 0.05°, and also improves the load in roll from 10Nm to 20Nm with control precision from 0.1°to 0.05°.The structure of drive element and cable, fairing configuration, overall dimension are optimized to make the device more suitable for the wind tunnel test.
