Buffer testbed of space docking mechanism

Abstract

The invention discloses a buffer test bench for a space docking mechanism, which comprises an active end and a passive end arranged opposite to each other, connected with respective translational braking mechanisms through a synchronous braking link; the active end is equipped with a tracking aircraft simulation piece and Its active docking mechanism; the target aircraft simulation part and its passive docking mechanism are installed on the passive end; the gravity balance device of the docking ring is also installed on the active end. Except for the above differences, the other structures of the active end and the passive end are exactly the same. The mass, inertia, length, and position of the center of mass of the simulated aircraft are the same as those of the real aircraft. The present invention can set the docking pose and initial velocity of the two aircrafts according to the test, because the motion process of the object under the condition of weightlessness is simulated by adopting the air flotation and low-friction technology, the simulation parts of the two aircrafts can be set under the force of inertia. Attitude and speed are docked to achieve the beneficial effect of the so-called "1:1 full physical simulation".

Description

technical field [0001] The invention relates to aircraft test equipment, in particular to a space docking mechanism buffer test bench for simulating the docking process of two space aircraft. Background technique [0002] At present, only Russia and the United States in the world can achieve space docking and complete the transfer of personnel and goods between two aircrafts in space. Russia's aircraft uses spacecraft, and the United States uses space shuttles. At present, only Russia produces the docking mechanism in the world (the United States buys Russian products). Russia has relatively complete test methods and technologies, which may involve national defense secrets. The patent of the equipment used for the docking buffer test of the space docking mechanism has not been found, but According to internal information and through investigations and exchanges in Russia, Russia’s early method of conducting a similar docking buffer test was to hang two "aircraft simulators" ...
