敷设橡胶圆板近场水下爆炸数值模拟
Numerical simulation of rubber coating circular plates subjected to near-field underwater explosion
摘要
Abstract
[Objectives] To study the coating effects on structures subjected to near-field underwater explosion,[Methods] the coupling Runge-Kutta Discontinuous Galerkin Method,Boundary Element Method and Finite Element Method are developed in this paper to solve a rubber coating circular plate subjected to near-field underwater explosion. The results are compared with experimentally obtained wet face pressure and bubble shape to verify the method,and the explosion bubble response to the flexible boundary is discussed.[Results] The results indicate that the rubber coating plate will shorten the pulse width of the shockwave,but the cavitation collapse will occur more easily. In addition,solid rubber coating has little effect on the deformation of the explosion bubble. [Conclusions] This research can provide a theoretical basis and technical support for the coating design and optimization of warships subjected to near-field underwater explosion.关键词
