Abstract
Portable crankling vibration test instrument, its composition includes the flexibility experimental facilities of measurement experiment material and measurement experiment material twist two parts.Two kinds of experiments are all to provide power using stepper motor, are transmitted by transmission device, by two The gear deceleration speed devices.Rotated in screw shell by leading screw when doing crooked experiment, drive bending detecting head to travel forward, and applying power is carried out to crooked experiment test specimen, and it is more long over time, and the flexural deformation of crooked experiment test specimen is bigger, and applying power is also bigger；When torsion test is done, gear wheel slowly rotates to make it produce deformation, then the moment of torsion for directly measuring test specimen diverse location by torque sensor.The present invention is workable, has a wide range of application, and cheap, substantially increases the precision of measurement bending experiment.
Description
Technical field
A kind of field the invention belongs to measure material mechanical performance instrument, and in particular to portable crankling vibration experiment
Instrument.
Background technology
Flexibility refers to strip rolled piece (type, rod, tubing) degree of crook in the longitudinal direction.Bent in every meter of length
Action is every meter of flexibility；Total action of total length bending is total flexibility with the ratio of total length.The crooked experiment of mechanical material
All be with torsion test be all material property fundamental test method.At present, the test instrument of in the market practice is measured by it
Mode can be divided into bending tester and torsion test instrument, and two kinds of instruments are individually present.Crooked experiment is typically embedded into omnipotent experiment
In machine function, price is caused very expensive.Also there is an other combination experiment platform, only carry out material mechanics experiment device
Cumulative fuselage is heavy, it is necessary to multiple loading devices, clearly, structure is not compact in a jumble for its shortcoming, serious waste field experiment
Ground and purchase funds.
According to pertinent literature, conventional measurement intensity and the device of the testing stand applying power of twist are heavy, only by moving
Dynamic detecting head changes the point of application, and the shape of measurable object is single, it is therefore desirable to redesign a kind of the curved of portable
Turn round composite test equipment.Such as patent publication No. for " Multifunctional material mechanics experimental device " of CN201020613430 discloses one
Multifunctional material mechanics experimental device is planted, 7 fonts loading column, the top press-in of 7 fonts loading column are connected with Universal base
Spigot nut set, loading screw flight connection spigot nut set, the upper end for loading screw rod is fixedly connected with the hand wheel, loading screw rod
Lower end is connected with pressure sensor planar slide, pressure sensor lower end connection pressurization round end.Its force application apparatus relies on manpower, can
Force is very small, can be only used to the theoretical experiment of student, it is impossible to carry out the measurement of big experiment part, and unitary function.As specially
" the crankling vibration testing machine " of sharp Publication No. CN105319135A discloses a kind of using leading screw change detecting head position force
The equipment of point, its structure drives the parallel slideway being fixed on nut to move using fixed leading screw, pair of nut, and test specimen is applied
Bending force, while the position of the point of application by another leading screw, pair of nut normal thereto come adjustment effect on test specimen,
And measure the deflection produced by the power and test specimen acted on test specimen respectively with pressure sensor and displacement transducer.Turning round
Turn to utilize Bevel Gear Transmission during experiment, bearing load is low, it is difficult to the experiment for needing force is done, and structural volume is huge.And for example
" mechanics of materials of bridge type beam structure is combined test bed " of the CN200620153488 of patent publication No. discloses a kind of bridge type beam knot
The mechanics of materials of structure is combined test bed, is characterized in:The pedestal of steel construction, girder both ends of the surface are made up of girder, strutbeam long, short strutbeam
It is upper vertically to connect I, II column, the affixed square beam in two columns top and constitute bridge type beam structure, can make directly with it in suit on square beam
The working frmae of line motion, working frmae lower end connection loading device, the girder side relative with short strutbeam, the big pipe top surface of I columns
The stress analysis experimental provision of connecting circular tube bending and twisting combined action, pipe bending and twisting combined action stress analysis experimental provision, connection
Torsional angle bar, beam of uniform strength experimental provision, fill strut and tie experimental provision on short strutbeam, strutbeam long fills the survey of straight beam pure bending direct stress
Determine experimental provision.Its complex structure, volume is heavy, and can applying power it is small, change measurement by the position for changing measuring probe
Point, lowering or hoisting gear is complicated, and levels of precision is not high.
In sum, using existing crankling vibration experimental facilities, it is impossible to realize to experiment material accurate measurement moment of flexure and torsion
Square, can not experimental facilities volume and price it is reasonable.Therefore, it is necessary to design a kind of cheap portable bending
Combination experiment instrument.
