Problems solved by technology

[0005] In terms of lunar exploration in deep space exploration, there are mainly two types of buffers used in the soft landing system of the probe: (1) in the Prospector series, lunar- the hydraulic buffers used in Luna-17 and Luna-24; (2) the aluminum honeycomb buffers used in the Apollo Lunar Module and the European Luna 2000, whose cushioning process is largely uncontrollable, and It is not easy to adjust the posture after buffering

Embodiment Construction

[0019] The structure of the multi-degree-of-freedom attitude-adjustable universal buffer is shown in Figures 1 and 2. The working principle of the multi-degree-of-freedom attitude-adjustable universal buffer will be described here.

[0020] The working principle of the universal buffer for multi-degree-of-freedom attitude adjustment is:

[0021] (a), when the aircraft collides, the impact force of the collision is transmitted to the lower support frame 1, the universal joint cross 6 and the upper support frame 8, and the first brake disc 4 and the second brake disc 5 rotate through their internal braking torque to produce corresponding The frictional resistance is used to buffer the inclined side impact; the braking torque of the brake disc can be adjusted according to the feedback data, so that the buffering is sufficient and controllable. At the same time, the electric current of the electromagnetic damper coil in the wall of the cylindrical piston rod 9 and the double-laye...

Abstract

The invention discloses a universal buffer for multi-freedom posture adjustment, and belongs to the field of configuration for buffer and posture adjustment for a used aircraft or other effective loads. The universal buffer mainly comprises a support structure consisting of a universal joint cross (6), a connecting frame (2), a lower support frame (1) and an upper support frame (2); the universalbuffer also comprises a bottom inclined energy buffer and inclined posture adjustment mechanism consisting of a brake disc arranged on the universal joint cross (6) and an inclined posture adjustmentgear; and the universal buffer also comprises a vertical energy buffer and vertical posture adjustment mechanism consisting of a cylindrical piston rod (9), a double-layer outer cylinder (11) and a corresponding coil in the middle of the universal buffer. The universal buffer overcomes the defects of the conventional buffer, and realizes controllability of a buffer process and adjustability of a buffer post posture.

Description

technical field [0001] The invention belongs to the field of configurations for cushioning and attitude adjustment of the aircraft or other payloads used. technical background [0002] In the field of aerospace, when a vehicle or payload collides with other objects, large instantaneous impact energies are generated. If these energies are not fully absorbed or dissipated, the aircraft or the payload and its internal scientific instruments will suffer from excessive structural deformation due to excessive shocks, or even cause the instruments to fail, thus failing to complete the task normally. [0003] Although the speed of the plane is not very high when it lands, due to the large mass of the plane, it will generate huge impact energy at the moment of collision with the ground, and it will also have a lot of kinetic energy during the next sliding process. If the buffer system of the aircraft cannot absorb most of the impact energy at the moment of landing, or cannot effecti...
