Problems solved by technology

However, due to the limitation of the radius of the wind tunnel, when the model moves with large amplitude and high frequency, the input acceleration required by the support system of the wind tunnel model will be quite large, which cannot be realized by the general drive unit, and the structure is complicated. Manufacturing, high assembly cost

Abstract

The invention discloses a wind tunnel model supporting device which comprises a movable platform, a clamping device, a first driving unit and a second driving unit, wherein the movable platform has three translational freedom degrees and at least one rotation freedom degree. The clamping device is connected with the movable platform and is used for fixing and supporting the model. The first driving unit and the second driving unit are arranged on the movable platform and used for driving the clamping device, and therefore, the clamping device obtains the freedom degrees of rotation in horizontal and transversal directions. The first driving unit comprises a first driving motor and a first rope traction mechanism. The second driving unit comprises a second driving motor and a second rope traction mechanism. The wind tunnel model supporting device with simple and reliable structure can realize six freedom degrees of the model in the wind tunnel test, effectively expand the model pitch and the roll amplitude capable of being realized by model supporting, and decrease the acceleration, the motion speed and the motion travel of the driving units through the first driving unit and second driving unit which are connected in parallel.

Description

technical field [0001] The invention relates to the field of wind tunnel experiment equipment, in particular to a wind tunnel model supporting device used for supporting models in wind tunnel experiments. Background technique [0002] Wind tunnel experiment is one of the three basic means of aerodynamic research, and the results of wind tunnel experiment have strongly promoted the development of aerospace industry. In the wind tunnel experiment, the aircraft model (hereinafter referred to as the model) is required to frequently make attitudes and actions such as pitch, yaw, roll, heave, lateral translation and longitudinal translation. In order to realize the above posture and action, the model must first be supported in the wind tunnel with a support system. This support is usually called the wind tunnel model support system, which is the mechanism to realize the attitude control of the model in the wind tunnel. In wind tunnel experiments, commonly used model support metho...
