Improvement and Taper Optimal Design of the Hydraulic Fast Connector

摘要

Improvement design was carried out to resolve the issue about easily damaged and difficult repaired planar seal for hydraulic fast connector. Based on original fast connector connection structure, adding a taper on male connector and female regulating part on female connector was more reliable because the planar seal was changed into the taper seal. When the contact surface was worn, it could be reseated by adjusting the female regulating part. A pivotal question was to design the reasonable taper for taper seal. In order to acquire the best taper, optimal design was carried out using finite element method, and the relationship between maximum contact stress and tape was gained. Simulation results showed that the best tapper could be gained when the big-endian radius of the taper was' 11.82 mm. The improvement and optimal design of hydraulic fast connector could quicken production with lower cost Thus it fully met the design requirements.
