Design and Experimental Validation on the Silicone Rubber O-ring Waterproof Structure of a Smart Ultra-Rugged Handheld Device
碩士 === 國立中興大學 === 機械工程學系所 === 107 === For an ultra-rugged handheld computer, the design for waterproof structures would usually follow the previous parameters, such as the diameter of silicone-rubber O-ring, the hardness and the amount of compression. Those parameters are then refined through multip...

Those parameters are then refined through multiple testing. As the circle of developing a new product is getting shorter and shorter, a more efficient design method is a must for the current trend. In the present study, experiments were conducted to establish the silicone-rubber stress-strain curves, which were used for conducting the finite element analysis. In order to validate the simulation, three actual products with silicone-rubber O-ring waterproof structure were used to find the correlation between the IPX7 immersion tests result and the simulation results. A critical pressure value to determine the waterproof ability was then established. To validate the critical pressure value, two silicone-rubber O-rings with different hardness (Shore Ⅰ, Shore Ⅱ) were applied and tested with the products. The result showed that the critical pressure value is reliable for determining the IPX7 waterproof ability. Shean-Juinn Chiou 邱顯俊 2019 學位論文 ; thesis 77 zh-TW |
