| Popis: | The traditional craft of marine launching rubber gasbag that made by hand laying cord fabric has the disadvantages of irregular reinforcing direction and discontinuity of cord, which leads to the limitation of bearing capacity of gasbag and poor reliability. Based on the analysis of the structure of the rubber gasbag and geodesic winding pattern used in marine launching, the winding process design and experiment of the fiber reinforced rubber gasbag are carried out to solve the problem. The numerical simulation of the wound rubber gasbag is established by the finite element software ABAQUS in order to study the geometrical and contact nonlinearity of the gasbag, and the nonlinear relationship of parameters in application process, and then compare the application performance with those of the traditional cord fabric placement molding. Finally, the winding pattern test and deformation simulation experiment are carried out to verify the fact that the reinforced rubber gasbag with glass fiber / polyurethane composite material has a higher bearing capacity compared with the traditional handmade rubber gasbag. Thus, it provides theoretical and experimental evidence for the winding process of rubber gasbag. |
