1. analysis model
The same rigidity material is used up and down, the lower plate is fixed on the upper plate, the section is pressed down 0-, and the normal work is 1.58mm- press 3.1mm.
2. boundary imposed
During the whole down pressure, the contact surface will be added with frictional contact coefficient of 0.1.
Fixing all degrees of freedom on the lower surface of the lower plate.
All degrees of freedom except for UY.
The upper surface of the upper plate is segmented under pressure 0mm-1.58mm-3.1mm.
3. overall deformation results
4. stress results
5. reaction force (bearing stiffness curve)
