Assembly test vehicle of airplane main landing gear

Abstract

The invention discloses an assembly test vehicle of an airplane main landing gear, and an air floatation platform and five servo electric cylinders are used for achieving six-freedom-degree movement of the main landing gear and rotation of a strut of the nose landing gear along an axle. The movement amount, along an X axis and a Y axis, of the main landing gear and the rotation amount, along a Z axis, of the main landing gear can be adjusted manually, the movement amount, along the Z axis, of the main landing gear, the rotation amount, along the X axis and the Y axis, of the main landing gear and the rotation amount, along the axle, of the strut of the main landing gear can be adjusted quantitatively through the servo electric cylinders, and the six-freedom-degree movement is achieved through real-time quantitative control. The assembly test vehicle of the airplane main landing gear is high in freedom degree, easy to align in an assembly process and capable of achieving the quantitative control in the assembly process and flexible manual adjustment, and therefore assembly accuracy of the main landing gear is greatly improved.

Description

technical field [0001] The invention belongs to the field of mechanical structure design, and in particular relates to an aircraft main landing gear assembly test vehicle. Background technique [0002] Chinese patent CN2782326 discloses a six-degree-of-freedom precision positioning workbench. The precision positioning workbench is guided by a flexible hinge, and the drive unit adopts a piezoelectric ceramic driver, which improves the displacement output resolution and positioning accuracy, and realizes the positioning of its mechanism. Compensation to achieve nanometer-level positioning accuracy. [0003] Patent CN101081504 describes a six-degree-of-freedom docking platform. This six-degree-of-freedom docking platform realizes six-degree-of-freedom movements by superimposing the functions of the plane adjustment mechanism and the vertical adjustment mechanism. [0004] The above-mentioned mechanism adopts the superposition of motion to realize the movement of six degrees of...

AI Technical Summary

Problems solved by technology

[0004] The above mechanism uses the superposition of motion to realize the movement of six degrees of freedom. The six degrees of freedom docking platform can be adjusted manually, but the degree of freedom cannot be quantitatively adjusted.

Although the six-degree-of-freedom precision positioning table can be quantitatively adjusted through the piezoelectric ceramic driver, some degrees of freedom that are not demanding cannot be manually adjusted flexibly and quickly

However, the handling of the entire mechanism cannot be realized, and the degree of freedom of the handling operation is not high.
