Description
Art
The invention belongs to the space tasks ground validation technical field such as spacecraft and detector, and in particular to provide spacecraft
The six degree of freedom microgravity environment of spatial movement ground validation.
Background technology
Currently, the core content of space tasks is Spatial Cooperation, and Spatial Cooperation is primarily referred to as including spacecrafts rendezvous
All kinds of in-orbit services, the supply of space station, reparation and spacefarer rotate.The general step bag that these space tasks are implemented
Include:The determination of task definition, the design to carry into execution a plan, scheme ground experiment checking, the development of task performer, scheme
Rail is verified, and six stages of last implementation of space tasks, each stage are indispensable.The ground implemented as space tasks
Verify key component, the target of ground experiment is the reasonability and technical feasibility of clarifying space task scheme, and its success with
It is no to depend greatly on whether used verification method is really to reflect to its space tasks implementation process feature.
Put it briefly, these features include:Space tasks implementation process is in microgravity environment and spacecraft attitude position is moved not
It is constrained etc..And reflection of the currently used ground validation method to features described above all exist it is clearly disadvantageous, such as:System
System emulation can not describe task process in real time;Semi-physical simulation is but logical although it is contemplated that the relative orbit operation of cooperative target
Often it is not related to the influence of microgravity environment, and also usually only a certain subsystem in space tasks or specific function is tested
Card, and the satisfaction of each subsystem performance is not meant to that the overall performance of integrated system meets.Considered in full physical simulation
Gravity compensation and conventional method without constrained motion have weight-loss method, liquid float glass process, Bubble-floating Method and suspension method.Weight-loss method it is common be
Parabolic flies and freely falling body, the shortcomings that the method be that the time is short, the space that takes is big, the space that can provide is limited and into
This height;The damping of liquid float glass process is big, maintenance cost is high and is only suitable for the situation of low-speed motion;Bubble-floating Method can only typically provide five freedom
The motion of degree, in the limitation of movement of vertical direction.Space shared by suspension method is small, not by spatio-temporal constraint, is gravity
The conventional method of compensation, suspension method can be generally divided into active gravity compensation and passive gravity compensation.The benefit of passive gravity compensation
It is relatively low to repay precision, has considerable influence to test effect;Active gravity compensation can improve compensation precision, but the gravity of active at present is mended
Compensation method is typically hung by single-point provides three-degree-of-freedom motion space or multi-point suspended offer six-freedom motion space, for
This target of spacecraft motion reappearance is realized, three-degree-of-freedom motion space is obviously inadequate, the six degree of freedom that multi-point suspended is provided
Space can cause test effect bad due to the difficult conduct of complicated, system, and therefore, development one kind can more truly reflect space
Task-cycle process microgravity environment is without constrained motion environment, to promoting future space experiment more precisely to enter on ground in advance
OK, to reduce developing risk, reliability is improved, shortens research cycle, reduces investment outlay, correlative study achievement is entered the world as early as possible
Leading ranks, significantly lift the space flight ability in China and the potentiality of sustainable development are very important.
