Device mainly has horizontal guide rail method and two kinds of arrangement of impact, and impact arrangement is because its experimental principle is simple, strong antijamming capability etc.
Advantage, it is to use wider a kind of test device and method at present.The design of ballistic pendulum be broadly divided at present suspension wire single pendulum and just
Two kinds of arm physical pendulum, wherein physical pendulum are mostly globality non-removable structure, and each several part component can not damage according to actual requirement and use
Consumption situation is changed.In addition, for different displacement measurement methods, such as High Speed Photography, Through Optical Interference Spectra, optical lever method
Deng, the versatility of physical pendulum structure is not high, repacking inconvenience, and on micro- in utilization Hall galvanomagnetic-effect measure laser Impulse coupling
The pendulum device of thin tail sheep not yet has been reported that.
The content of the invention
The purpose of the present invention is the deficiency for existing physical pendulum, there is provided each several part can conveniently be dismantled, combine and changed to one kind
The pendulum device for being used to determine small displacement during laser Impulse coupling of component.
In order to solve the above-mentioned technical problem, the present invention provide it is a kind of be used for laser Impulse coupling during determining displacement answer
Pendulum device, both ends are followed successively by from top to bottom and are put using needle point as the physical pendulum crossbeam of fulcrum, for connecting physical pendulum crossbeam and target
Put the swing arm of frame, put structure for producing the right angle arch magnetic of uniform steady magnetic field；Physical pendulum crossbeam is placed by the fulcrum at both ends
On physical pendulum swing span；A screw type target folder is separately installed with the center position of target placing frame or so frame wall；Right angle
Arch magnetic is put structure and is connected on the lower frame of target placing frame, and right angle arch magnetic is put structure and target placing frame and mutually hung down
Directly.
Further, the right angle arch magnetic puts structure both sides homopolarity two pieces of Nd-Fe-B permanent magnets staggered relatively, and spacing is adjustable.
Further, the needle point fulcrum of physical pendulum crossbeam is threaded steel structure, and support needle point is provided with physical pendulum rocker
The fulcrum face of fulcrum, fulcrum face are provided with two slick spots being recessed to place two needle point fulcrums.
Further, physical pendulum each several part is attached fixation using screw.
Further, physical pendulum crossbeam and swing arm are made using glass fiber material.
Further, target placing frame is made using wood materials.
Compared with prior art, its remarkable advantage is the present invention, and (1) pendulum device of the present invention is axial symmetry and detachable
Formula structure, each several part component can be changed with loss situation according to the actual requirements, physical pendulum fulcrum use steel needle point structure with
Reduce friction；(2) pendulum device of the present invention can determine micro-displacement in laser Impulse coupling dedicated for Hall galvanomagnetic-effect method
Measurement, it can also be used to which the other method such as light beam deflecting method, High Speed Photography determines laser Impulse coupling displacement, and versatility is high.
