Structure analysis and optimization design of the Yx-ring

摘要

The optimization design of Yx-ring for a certain hydraulic actuator is studied. Firstly, parameterized model of Yx-ring is established by APDL language of ANSYS. Then, based on software ISIGHT, the main factors affecting the radial force and the maximum contact pressure on the lip are determined by the design of experiment. Furthermore, optimal shape of Yx-ring is achieved by virtue of intelligent optimization algorithm. Compared to the original structure, the total radial force at the lip of the new configuration is decreased by 13.9%, reducing the abrasion at the lip, the maximum contact pressure at the lip is increased by 16.8%, improving the sealing performance. The obtained optimization scheme provides a new idea for the design of other seal structures.
