Zusammenfassung:The invention provides a back support mechanism for a wind tunnel experiment. The back support mechanism comprises a yawing motion mechanism and a pitching motion mechanism which are superposed together to respectively realize a yawing angle and a pitching angle of a wind tunnel experiment model. The pitching motion mechanism is fixed on a yawing motion plate in the yawing motion mechanism, and the wind tunnel experiment model is fixed on a model support arm in the pitching motion mechanism. The back support mechanism for the wind tunnel experiment can realize linkage of yawing motion and pitching motion. According to the invention, a planar slider-crank mechanism motion principle is adopted, linear motion is converted into rotary motion, and the linear motion is obtained through a spiraltransmission mode. The mechanism is high in rigidity, high in bearing capacity and high in reliability, and provides guarantee for a wind tunnel model experiment adopting a back support form. 一种风洞实验用背支撑机构,包括:偏航运动机构和俯仰运动机构,两机构
