Surface far from material, i.e. the surface of material is non-loaded, the recess formed on material surface, and material carries out returning for preset time
Bullet restores, after material is kept for certain recovery time, into S5.
S5, by material placing casing automatically from second pressure contact element 310b immediately below be moved to the first pressure contact element 310a just under
Side, the first actuator 210a work, the surface at the center of the contact surface slight squeeze recess of the first pressure of driving contact element 310a, this
Height H3 after the recovery of the contact surface of the pressure of Shi Jilu first contact element 310a, is calculated the thickness T3=∣ H3-H1 after material restores
∣ is simultaneously recorded, and the recess value P1=T1-T2 of material, the residual indentation value P2=of material is so far calculated automatically by TT&C system
T1-T3。
The range of the preset pressure value is 10g-500g；The range of second loading force is 0-1000kg.
