| Summary: | 博士 === 國立成功大學 === 工程科學系碩博士班 === 97 === The main purpose of this research is to study the difference between 2.5D and 3D air cushion structures with a curved upper surface. Viable designs are evaluated and samples are made, following the principle of composite force to integrate the upper and sideward surfaces with connective ribs. The ribs also provide a supporting function for the air cushion. A higher lever air cushion was made through extending the sideward curved surface of the supporting rib to the height which has never been done. After inflated with approximate inner pressure, the test results for the first version of 3D air cushions show that the energy rebound are 25% relatively more than the 2.5D air cushion, which accompany with a better shock absorption function, including a descend acceleration of 21.5 m/S2 and an increase 2mm penetration height. The higher lever one even provide 48% relatively energy rebound more than the 2.5D air cushion. Optimal designs can be obtained through computer simulations for the rib structures of the 3D air cushion using simplified models which improve the design work considerably.
