| Abstract: |
| It is important to study characteristics of liner and composite double shells and composite pressure vessel,the stress and strain characteristics of a TC-4 titanium liner/T1000 carbon fiber composite over-wrapped pressure vessel was analyzed by means of netting theory optimization.The influence of fiber stresses regarded as independent variables for the liner and composite double shell was studied at different pressure,such as zero pressure,working pressure.Test pressure and burst pressure,the vessel performance was influenced by the mechanical characteristics of the liner and composite shell and was summarized and the optimized analytical method was provided.It is a significant method for similar structure calculation and similar products optimizing design. |
