Embodiment Construction
[0018] The present invention will be further described below in conjunction with accompanying drawing.
[0019] A wind tunnel test model support mechanism based on a parallelogram mechanism, consisting of a base 1, a rotating servo motor 2, a rotating rod 3, a swinging servo motor 4, a swinging rod one 5, a swinging rod two 6, a swinging rod three 7, and a swinging rod four 8. Rolling servo motor 9, rolling fixed bracket 10, model support rod 11, aircraft model 12, etc. are installed and connected. The rotating servo motor is fixed on the base, and the rotating rod is fixed on the motor shaft of the rotating servo motor to form a rotating mechanism. The rotating rod is perpendicular to the base, and the rotating servo motor drives the rotating rod to rotate 360 degrees around its axis; one end of swinging rod 1, swinging rod 2, swinging rod 3 and swinging rod 4 are respectively connected by rotating pairs to form a parallelogram four-bar linkage mechanism, The other ends of ...

A wind tunnel test model support mechanism based on a parallelogram mechanism belongs to the technical field of aircraft development and test equipment. It consists of base, rotating servo motor, rotating rod, swinging servo motor, swinging rod 1, swinging rod 2, swinging rod 3, swinging rod 4, rolling servo motor, rolling fixed bracket, model support rod, and aircraft model installation. The rotation servo motor, swing servo motor, and roll servo motor drive and control the rotation mechanism, the swing rotation mechanism and the roll mechanism to realize the three-dimensional movement of the aircraft model around the virtual center under the guidance of the mechanism, and realize the deflection of the three degrees of freedom of the aircraft model. Navigating, pitching and rolling motions. The model support mechanism can ensure that the aircraft model has a large enough range of motion, and keeps the position of the center of mass of the aircraft model under the guidance of the mechanism. The effect of the test.
Description
technical field [0001] The invention relates to an aircraft model support mechanism for an aircraft to carry out wind tunnel tests, in particular to the structure of a wind tunnel test model support mechanism capable of guiding an aircraft model to realize three-dimensional rotation around a virtual center, and belongs to the technical field of aircraft development and test equipment. Background technique [0002] Wind tunnel test is an essential link in the development of aircraft. The development of each aircraft requires a large number of experiments in the wind tunnel. The wind tunnel test of aircraft is inseparable from the model support system. The performance of the model supporting mechanism for the wind tunnel test of the aircraft model directly affects the effect of the wind tunnel test of the aircraft model, thereby affecting the quality or success of the aircraft development. Contents of the invention [0003] The purpose of the present invention is exactly to ...
