Mud ground, simulates smooth ceramic tile surface compared with low roughness friction belt.Friction belt tilts to install, and is positioned at the installation slope of friction belt at half sole
Degree is for 0-25 °, and after being positioned at, at the palm, the gradient of friction belt is 0-15 °.
The present invention also provides for the method applying above-mentioned sole abrasive resistance test device to test sole abrasive resistance, is by reality
Test platform base fixing after, fix shoes to be measured with foot model, adjust frictional experiment device and make it be fully contacted with shoes bottom surface；
Utilizing lever principle, with the junction of foot model as fulcrum bottom elastic device, foot model is lever, and hydraulic lifting arm is downward
Elongation, slaps the abrasion that contacts with friction belt after making shoes；Hydraulic lifting arm upwards shrinks subsequently, and contraction process is divided into before and after two
Section: leading portion, hydraulic lifting arm upwards amount of contraction is less, and elastic device maintains static, and fulcrum is the most motionless, in shoes half sole
Back segment horizontal component contacts friction, back segment with friction belt, and hydraulic lifting arm is upwards retracted to certain amount of contraction time receiving, if being further continued for
Upwards shrink and drive elastic device is moved up, cause rising bottom elastic device, cause fulcrum to rise, shoes half sole front end
Upturned portion just can contact friction, subsequently hydraulic retract bar stretch downward with friction belt, and spring force makes fulcrum reset.
Beneficial effects of the present invention is as follows:
Present configuration is compact, reasonable, easy to operate, and this device utilizes the conversion of " people is motionless, and ground is moved ", by friction
In experimental provision, friction belt slaps hydraulic lifting arm simulation foot in partial frictional, foot's analog with before and after sole respectively
The characteristics of motion of foot when the simulation people such as bearing capacity walks；The change being recorded moment of torsion by torque sensor obtains friction indirectly
The change of coefficient, thus characterize the degree of wear of sole so that the data of acquisition are more direct, more accurately.
Foot of the present invention analog utilizes the lever principle of seesaw, with bottom elastic device with foot model
Junction is fulcrum, and foot model is lever.When the hydraulic lifting arm stretch downward that bottom is connected with foot model rear end, described
Elastic device is motionless, and foot model rear end upwarps around fulcrum around settlement of support, foot model front end, and rear end contacts with friction belt, mould
Intend the palm and ground friction state after shoes；When described hydraulic lifting arm upwards shrinks, owing to footwear half sole length relatively Heel is long
And foot model front end upwarps, solely utilize lever principle that footwear half sole cannot be made completely worn out, so being divided into forward and backward two sections
Wearing and tearing, leading portion, hydraulic lifting arm upwards amount of contraction is less, and elastic device maintains static, and fulcrum is the most motionless, now
The horizontal component of friction tape wearing shoes half sole posterior segment；Back segment, hydraulic lifting arm is upwards retracted to certain amount of contraction time receiving, if
It is further continued for upwards shrinking and elastic device will be driven upwards to shrink, cause rising bottom elastic device, cause fulcrum to rise, make footwear
The upturned portion of half sole front end relatively sinks thus contacts with friction tape, and hydraulic lifting arm extends still further below subsequently, elastic device
Resetting under the action of the spring, hydraulic lifting arm continues stretch downward and begins to wear out the most again Heel.The present invention utilizes lever principle,
Dexterously complicated walking movement state dress is become three sections of simple lever motions, well after simulation people's half sole when walking
The palm alternately rubs with ground, due to slap before and after sole be all transience and friction tape friction avoid the occurrence of continued wear and produce
Material for sole of shoe is affected by heat amount, more preferably simulates truth, it is to avoid experimental error occur.
The present invention arranges torque sensor between driving motor and wear device, when sole abrasion, and sole and friction
Generation is changed by the coefficient of friction between band, thus changes the frictional force between sole and friction belt so that transmission rolling shaft is turning
Time dynamic, suffered resistance reduces, and then changes torque, and torque sensor can capture this change, by conversion,
Thus measure sole abrasion degree more directly and accurately.
