Sloshing analysis of cylindrical shell with rubber-covered surface
- Mitsubishi Heavy Industries Ltd., Nagasaki (Japan)
The estimation of sloshing in containers is more practically important in marine, aerospace, and civil engineering. Although considerable theoretical works have been done on this problem, little can be found in the literature about the dynamic interaction between liquid and membrane rubber. The present paper describes a new sloshing analysis of a rigid circular cylindrical tank with rubber-covered surface. The static membrane tension force of rubber is controlled in order to avoid the resonance of seismic excitations. The accurate analytical model for treating the coupled oscillations of a liquid and a surface rubber have to be based on the assumption of the large deformation and material nonlinearity of rubber, and the convective terms and viscosity of containing liquid. The new method is, however, the first step of the development of the fully nonlinear numerical analysis. The nonlinear phenomena of coupled system are supposed to be estimated by the present method which considered the nonlinearity of rubber and potential flow of containing liquid. A finite element formulation of membrane theory is given, and Newmark-{beta} method is used to solve the numerical time integration. The present analytical method is verified by comparison of linear analysis with experiment under the horizontal external impulsive load.
