The Design of Hydraulic Cylinder for Measuring the Contact Stress of the Bud Type Seal Ring

摘要

At present, the bud type rings are widely used in the hydraulic cylinder piston rod seal, but there is no corresponding detection method to measure the contact stress when the seals are in the dynamic sealing condition. However, the contact stress is very important for analyzing the performance of the seals. A method for measuring the contact stress is presented in this paper, and the design of major parts of the test cylinder and the selection of seals are emphatically introduced.
