| Summary: | 碩士 === 國立屏東科技大學 === 車輛工程系所 === 101 === The purpose of this research is to investigate the design and fabrication of a pressure tank which will be used for the storage of oxidizer of hybrid rocket. In the firt place, pressure tank is designed using CAD and CAE technology, including aluminum liner design, filament winding design, epoxy selection, etc. Aluminum liner is fabricated by using welding to assemble the cylinder and bulkhead. Filament winding is used to reinforce the aluminum liner. Finite element analysis (FEA) is used to evaluate the structure stiffness and strength of pressure tank. Experimemtal modal analysis (EMA) is used to validate the finite element model in order to obtain equivalent model. This validated model is then used to analyze the stiffness and strength of pressure tank. Epoxy resin is of concern since the high curing temperature may cause the thermal stress problem which leads to de-bonding between aluminum liner and composite laminate. Thermal analysis using FEA is therefore required. Hydaulic test is conducted on the pressure tank eventually. Strain gage are used to measure the deformation of pressure tank. The test results show that no leakage occurs for the pressure tank.
