Research on Movement Relationship and Multi-Axis Motion Control Strategy for the Big Attack Angle Device of the Low-Speed Wind Tunnel

For the big angle attack device of 4m×3m low-speed wind tunnel, the attack angle device α change is realizes through the triangle link block organization, realizes angle of attack Alpha uniform speed revolving is a misalignment speed control process. In order to guarantee the blocking in realizes the angle of attack Alpha and in the angle of slide Beta pinpointing process, according to the request angular speed uniform speed rotation, and guaranteed that the model center does not deviate in the rotation process the wind tunnel center, this article, in the angle of attack Alpha organization, the angle of slide Beta organization, Y to the elevating mechanism, Z carry on the comprehensive mathematical analysis to the crosswise translation organization speed and the potential motion relations in the foundation, has conducted the deep research to the multiple spindle linkage speed and the position control method, finally uses the control hypothesized kingbolt, Alpha, Beta, y, the z organization position follow.
