A morphing wing follower loading mechanism based on parallel cable drive

Abstract

A deformable wing follow-up loading mechanism based on parallel cable drive relates to the field of aerospace equipment. The present invention solves the problem that existing loading test equipment cannot simulate harsh, complex, and changing aerodynamic environments, making it difficult to accurately verify indicators such as the stiffness, stability, and load-bearing capacity of the wing structure, which is not conducive to judging the performance of the wing. In the present invention, one end of all ropes is fixed to the force-loading dynamic platform assembly and the wing surface, and the other end is connected to the twisted shaft by passing through a series of pulleys on the static platform rope drive module. During the follow-up loading process, the position of the dynamic platform in space is adjusted by the motor-driven screw and twisted shaft, so that the spatial orientation of several loading cables connected to the force-loading dynamic platform assembly changes, and then the tension of the rope connected to the surface of the tested wing is adjusted to change the pulling force applied to the wing surface, so as to simulate the changing aerodynamic loads on the folding wing during the unfolding process. The present invention is used to achieve multiple aerodynamic load simulation effects.

Description

Technical Field

[0001] The present invention relates to the field of aerospace equipment, and in particular to a deformable wing follower loading mechanism based on parallel cable drive. Background Art

[0002] As the requirements for comprehensive aircraft performance continue to increase, so too do the requirements for aircraft design and loading testing. The wings are the primary factor affecting aircraft performance. The wing's strength, stiffness, deformability, and aerodynamic performance, among other factors, impact the overall performance of the aircraft. Loading testing, as the only step in verifying and evaluating wing performance, significantly impacts wing performance indicators through its accuracy. While existing loading testing equipment can apply loads to several locations on the wing, the direction of the test loads is often fixed, allowing only a few fixed scenarios to be simulated. It's unable to simulate harsh, complex, and changing aerodynamic environments, making it difficult to accurately verify indicators such as the stiffness, stability, and load-bearing capacity of the wing structure. This hinders both the performance evaluation and the design and improvement of the wing. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following effects:

[0016] The present invention's parallel-cable-driven morphing wing follower loading mechanism possesses both movement and rotational degrees of freedom to adjust the magnitude and direction of the cable tension. In this invention, all cables are fixed at one end to the force-loading platform assembly and the wing surface, while their other ends are routed through a series of pulleys on the static platform's cable drive module and connected to a twisted shaft. During the follower loading process, a motor-driven screw and twisted shaft adjust the platform's spatial position, changing the spatial orientation of the multiple loading cables connected to the force-loading platform assembly. This in turn adjusts the tension of the cables connected to the wing surface under test, altering the tension applied to the wing surface to simulate the varying aerodynamic loads experienced by a folding wing during deployment. During follower loading, the platform possesses both movement and rotational degrees of freedom to adjust the magnitude and direction of the cable tension. The 3R3T cable-driven parallel mechanism, designed based on the 2R3T mechanism, offers a large rotational workspace around the platform axis. The 11 degrees of freedom design allows for extensive adjustment of load intensity and direction, enabling more comprehensive simulation of the load environment.

[0017] 2. The deformable wing follower loading mechanism based on parallel cable drive of the present invention changes the length and direction of the cable respectively through the screw drive module and the cable drive module, which has a simple principle and is easy to control.

[0018] 3. The parallel-cable-driven deformable wing follower loading mechanism of the present invention adopts a modular design with single parts, simple structure, good interchangeability and easy installation.

[0019] 4. The parallel-cable-driven deformable wing follower loading mechanism of the present invention has many redundant degrees of freedom, and can adjust the tension of the rope connected to the tested folding wing 51 over a wide range, thereby achieving a variety of aerodynamic load simulation effects.

[0020] 5. The parallel-cable-driven deformable-wing follower loading mechanism of the present invention adjusts the direction of the test load by introducing a pulley and utilizing its flexible direction-changing feature. BRIEF DESCRIPTION OF THE DRAWINGS
