| For rigid body frictionless requirements of ultra-low frequency suspension reciprocating motion, an innovative
frictionless cylinder-piston structure was presented. A stress calculation model of frictionless cylinder -piston was built.
The stress calculation formula of cylinder and piston structure was made. A frictionless cylinder-piston of the air film
modal was established by ANSYS Workbench. Air film pressure distribution along the axial piston was appeared after
calculation. and the pressure was loaded into the frictionless cylinder piston by the fluid-structure coupling module.
Stress and strain distribution of the results was obtained by linear static structure analysis module-Static Structural
calculation. The results were analyzed, and solutions were put forward for unreasonable place of frictionless cylinder-
piston structure. |
