The realization means of wheel is identical, is all to realize slide block motion in support slideway by screw-driven, and pre-bearing up pulley is mainly used in experiment
The tensioning of front steel wire rope.
In conjunction with Fig. 6, experiment measuring table 2 is by line style slide rail 2-1, positive stop 2-2, linear displacement potentiometer 2-3, slide block
2-4, rope attachment cap 2-5, sensor connecting piece 2-6, extension spring 2-7, extension spring support B2-8, connector A2-9, connector
B2-10, soket head cap screw 2-11, scale 2-12, nut 2-13, pull pressure sensor 2-14, pressure head 2-15 form, wherein
Extension spring support B2-8 is made up of shaft end ring 2-8-1, support 2-8-2, bearing pin 2-8-3.Two lines type slide rail 2-1, linear displacement
Potentiometer 2-3 is fixed by screws in mounting bracket 1-10 of assistance platform, and linear displacement potentiometer 2-3 records experimentation
The displacement that middle measuring table occurs.Connector A2-9, connector B2-10 are connected by screw.Slide block 2-4 passes through screw and company
Fitting B2-10 is connected.There is a slide block 2-4 on every line style slide rail 2-1, so make motion more steady, by both groups
Close the steady compressive deformation realizing soft tissue.Pull pressure sensor 2-14 is threadedly attached on fitting B2-10, and passes through spiral shell
Female 2-13 fixes, the deformation power that in pull pressure sensor 2-14 record experimentation, soft tissue occurs, when power is more than the valve set
Think during value that soft tissue comes in contact.Extension spring support B2-8 and rope attachment cap 2-5 is fixed on connector by same screw
On A2-9, extension spring 2-7 provides pulling force upwards for experiment measuring table, it is to avoid affect slide downward at self gravitation.Scale
2-12 is easy to estimate the strain of soft tissue in experimentation, prevents excess compression from destroying soft tissue sample.Positive stop 2-2 plays
The effect of mechanical position limitation.The shaft end ring 2-8-1 of extension spring support B2-8 axially positions for bearing pin 2-8-3.
Pull pressure sensor 2-14 end can install two kinds of different survey tools.One, end is installed pressure head 2-15, can be entered
The experiment of row uniaxial compression, stress relaxation and creep test.Uniaxial compression experimentation: this experiment steel wire rope 1-8 end is wrapped in
On the pulley 1-2-6 of regulating wheel 1-2.The soft tissue sample of well cutting is put into the glass dish 1-13 interposition having normal saline
Put, first the position of pressure head 2-15 is carried out presetting before experiment, i.e. adjust suitable at scale 1-4 of mounting bracket 1-10 graduation mark
The displacement that position makes pressure head downward is less than the 40% of tissue samples thickness, prevents tissue to be subject to crushing.Slowly rotate regulating wheel screw
1-2-1, by screw-driven, drives regulating wheel slide block 1-2-2 to slide in tension pulley support 1-2-3 slideway, steel wire rope 1-8 to
Under pull experiment measuring table 2, when the force data that pull pressure sensor 2-14 collects more than setting value time, pressure head 2-15 is with soft
Tissue sample contact, starts to record the displacement data of linear floatingpotential meter 2-3, when positive stop 2-2 moves to and install prop up
During frame 1-10 contact, stop motion.Then rotating backward regulating wheel screw 1-2-1, now experiment measuring table 2 can be in extension spring
Slowly rising under the pulling force effect of 2-7, return to original position, experiment terminates.Stress relaxation experimentation: the same with uniaxial tests,
Pressure head 2-15 position is carried out presetting.Quick rotation regulating wheel screw 1-2-1, makes positive stop 2-2 move to as early as possible and installs to prop up
Frame 1-10 contact position, keeps ram position 20～about 30min now, prolongation over time, the deformation power of soft tissue
Meeting is more and more less and tends towards stability, the data of two sensors of collection period.Creep test process: when carrying out this experiment, steel wire
Rope 1-8 end hangs the counterweight of certain mass, and the lower end of extension spring 2-7 departs from extension spring support B2-8, adjusts mounting bracket 1-10
Graduation mark is in the position bottom of scale 1-4.Steel wire rope 1-8 can pull under the effect of Weight gravity experiment measuring table 2 to
Lower motion, causes tissue deformation with soft tissue after contacting.Increase over time deformation quantity can be gradually increased, record experimentation
In the data of two sensors.Its two, end install puncture needle, can carry out puncture experiment.Puncture experimentation: puncture real
Test similar with uniaxial compression experiment, first adjust the mounting bracket 1-10 graduation mark correct position at scale 1-4.Slowly rotate and open
Bearing up pulley screw 1-2-1, puncture needle can contact with soft tissue, punctures, insert.The data of two sensors in record experimentation.
