Abstract
The utility model discloses a kind of damping structures for low thrust measuring device, including metal connecting plate, two rows of circular grooves are opened up on metal connecting plate, often arrange four, circular magnet is set in circular groove, and circular magnet is mounted on using trip bolt above metal connecting plate；Damping structure provided by the utility model for low thrust measuring device, the purpose that circular magnet and metal connecting plate are installed together is to greatly save the installation space of low thrust measuring device.
Description
Technical field
The utility model belongs to the thrust measurement field of electric propulsion engine, furtherly more particularly to a kind of for small
The damping structure of thrust-measuring device.
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
It expands 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 generate setting for thrust
It is standby.Its advantages of is no longer to need using solid or liquid fuel, to eliminate complicated storage tank, pipeline, engine chamber, spray
The fuel carrying amount of spacecraft can be greatly decreased in pipe, corresponding cooling body etc..
The specific impulse of electric propulsion engine is very high, but thrust very little, generally only has mN μ N levels, to verify engine
Performance, it is necessary to be measured to its thrust.The damping system of low thrust measuring device is not by being specifically designed at present, generally
All it is one magnetic circuit damping system such as Fig. 1 of installation on the running bases being connected with engine, metal connecting plate (start by connection
Machine) it moves forward and backward, cutting magnetic line generates electric current, and electric current forms magnetic force in magnetic field, and prevents the front and rear fortune of metal connecting plate
Dynamic (magnetic force is opposite with the direction of motion of connecting plate), so as to form magnetic circuit damping structure.The purpose is to work as engine to be in shakiness
Surely when being swing state, by the damping system engine can be allowed to settle out as early as possible, the structure is required
The installation space size of low thrust measuring device is bigger, is not suitable for low thrust measuring device compact to design.
Utility model content
The utility model is to solve above-mentioned technical problem and the technical solution adopted is that provide a kind of for low thrust measurement
The damping structure of device, wherein, specific technical solution is：
Including metal connecting plate, two rows of circular grooves are opened up on metal connecting plate, often arrange four, circular magnetic is set in circular groove
Iron.
The above-mentioned damping structure for low thrust measuring device, wherein：Circular magnet is mounted on gold using trip bolt
Belong to above connecting plate.
The above-mentioned damping structure for low thrust measuring device, wherein：The circular magnet is Nd-Fe-B permanent magnetic.
The utility model has the advantages that compared with the prior art：Circular magnet and metal connecting plate are mounted on
Purpose together is to greatly save the installation space of low thrust measuring device.
Description of the drawings
Fig. 1 is the structure diagram of magnetic circuit damping system in the prior art.
Fig. 2 is the structure diagram of the damping structure provided by the utility model for low thrust measuring device.
Fig. 3 is the side structure schematic diagram of the damping structure provided by the utility model for low thrust measuring device.
In figure：
01 metallic plate, 02 magnet
1 metal connecting plate, 2 circular magnet
Specific embodiment
The utility model will be further described with reference to the accompanying drawings and examples.
The utility model provides a kind of damping structure for low thrust measuring device, the scheme that the utility model uses
It is to be installed together circular magnet 2 and metal connecting plate 1, it, can be directly using fastening using high magnetic Nd-Fe-B permanent magnetic
Screw is mounted above；Specifically metal connecting plate 1 is slotted, circular magnet 2 is mounted above, circular magnet 2 and metal
Connecting plate 1 reforms into one, spatially just similar one piece of thin plate, greatlys save the installation space of low thrust measuring device.
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.
Claims (3)
