Lin Wang, Shuaishuai Zhu, Xiaogang Qian

Be aimed at the speciality and complexity of the submersible collision problem, based on the nonlinear finite element method and considering the influence of structural contact and friction during contact collision and the additional water quality of submerged underwater collision, A simulation model for the contact collision between cylindrical pressure-resistant structure and silt is established. The speed, acceleration, maximum stress/strain and impact depth of the pressure shell are analyzed by comparison of four working conditions. The results show that the nonlinear finite element method can accurately analyze the submerged contact collision process.
