Description
Technical field
Space electric propulsion motor power fields of measurement is the utility model is related to, furtherly, more particularly to a kind of application
In the resilient support assemblies of low thrust measurement.
Background technology
Traditional space flight Push Technology is that vehicle is sent into predetermined space track using chemical energy and realizes that spacecraft exists
The technology that trailer moves, is primarily referred to as liquid and Solid-state Chemistry promotes.The characteristics of chemical propulsion is most prominent is can to provide high thrust,
It is the most commonly used Push Technology of space industry all the time.But with human use and the scope and depth in exploration of the universe space
Expand significantly, traditional chemical propulsion can not meet needs, its most important deficiency is that energy density is low.New propulsion skill
For art is relatively traditional chemical propulsion technology, refer to that space flight promotes basic principle or energy mode to be different from chemical propulsion
Non-chemical propulsion.Electric propulsion system, also referred to as electric engine, are a kind of not depend on chemical combustion with regard to that can produce setting for thrust
It is standby.Its advantages of is no longer to need to use solid or liquid fuel, eliminates complicated storage tank, pipeline, engine chamber, spray
Pipe, corresponding cooling body etc., can be greatly decreased the fuel carrying amount of spacecraft.
The specific impulse of electric propulsion engine is very high, but thrust very little, generally only has mN or μ N levels, to verify engine
Performance, it is necessary to measured to its thrust.The structure of low thrust measuring device is mainly day flat structure, such as Fig. 3 at present, is started
Machine thruster and rudder balance are mutually balanced counterclockwise and clockwise by supporting point in torque, when thruster produces thrust,
Its reaction force acts on a sensor, the numerical value of thrust is read by sensor controller.The thrust-measuring device of its flat structure
Its edge of a knife support usage time is grown, and the edge of a knife and edge bearing are easy to wear, and the edge of a knife is placed directly in when causing deterioration in accuracy, and installing
On edge bearing, due to its limited length, cause balance moving frame that sidesway easily occurs and rocks, so as to deviate normal equilibrium position, give
The routine use of measuring device is made troubles.
Utility model content
The utility model is to provide one kind applied to low thrust survey to solve the technical solution that above-mentioned technical problem uses
The resilient support assemblies of amount, wherein, concrete technical scheme is：
Support chip, the end set clamping metal derby for being suspended vertically support chip, per one end are suspended vertically including one
Portion sets two blocks of clamping metal derbies, and two pieces of clamping metal derby clampings are suspended vertically support chip.
The above-mentioned resilient support assemblies for being applied to low thrust measurement, wherein：The support chip that is suspended vertically is elasticity gold
Belong to block.
The above-mentioned resilient support assemblies for being applied to low thrust measurement, wherein：The clamping metal derby is rectangular shape.
The above-mentioned resilient support assemblies for being applied to low thrust measurement, wherein：Four locks are set on the clamping metal derby
Tight screw hole.
The utility model has the advantages that relative to the prior art：Support chip is suspended vertically using one kind to substitute
Traditional edge of a knife and edge bearing structure, its major advantage are service life length, and supporting point will not shift, and antijamming capability is very
It is high.
Brief description of the drawings
Fig. 1 is the structure diagram applied to the resilient support assemblies of low thrust measurement.
Fig. 2 is the structure diagram applied to the resilient support assemblies of low thrust measurement.
Fig. 3 is the structure diagram of current low thrust measuring device.
In figure：
12 locking screw wire hole of clamping metal derby, 3 elastic metallic block
01 balanced weight, 02 sensor reaction control system(RCS), 03 thruster 04 supports 05 calibrating plate
Embodiment
The utility model will be further described with reference to the accompanying drawings and examples.
A kind of resilient support assemblies applied to low thrust measurement that the present invention uses, including one be suspended vertically support
Piece, the end set clamping metal derby 3 for being suspended vertically support chip, each two blocks of clamping metal derbies 3 of end set, two pieces of folders
Hold the clamping of metal derby 3 and be suspended vertically support chip；The support chip that is suspended vertically is elastic metallic block 3；It is described clamping metal derby 3 be
Rectangular shape；Four locking screw wire holes 2 are set on the clamping metal derby 3.
A kind of resilient support assemblies applied to low thrust measurement that the present invention uses, resilient support assemblies preferably solve
The above-mentioned puzzlement of traditional edge of a knife support, can keep precision constant for a long time, and reduce and frequently adjust balance in routine use
The trouble of balance, it is very easy to use, it is suspended vertically support chip using a kind of and substitutes traditional edge of a knife and edge bearing structure, it is led
It is service life length to want advantage, and supporting point will not shift, and antijamming capability is very high, and the present invention solves traditional edge of a knife substantially
Easily moved with edge bearing, the shortcomings that structural instability.
Although the utility model is disclosed as above with preferred embodiment, so it is not limited to the utility model, any
Those skilled in the art, without departing from the spirit and scope of the utility model, when can make a little modification and it is perfect, therefore this
The protection domain of utility model, which is worked as, is subject to what claims were defined.
