摘要: 发展了一种流固耦合的动力学数值仿真方法,用以模拟弹性结构在其运动诱导的非定常气动载荷作用下的动态响应.针对给定的运动规律,对不可压流场采用侵入式边界方法求解了非定常气动载荷,其中未计及弹性结构变形对流场的影响.对非定常气动载荷作用下的薄壁弹性结构进行了瞬态动力学数值模拟.以地面试验状态的整流罩分离为例,对刚性体及是否考虑表面气体压力作用的柔性体等情形下的整流罩的动力学行为进行了对比分析,验证了发展的流固耦合动力学仿真方法的可行性.Abstract: A fluid-structure interaction (FSI) method for the simulation of the motion of elastic structure under the unsteady aerodynamic load induced by its motion was developed. For a given motion of the structure, the unsteady aerodynamic load of incompressible fluid was solved by immersed boundary (IB) method without the influence of elastic deformation for fluid being considered. The transient dynamic simulation of the thin-walled elastic structure was done. For a fairing separation in the ground test state, by comparing the deformation of fairing in different cases: rigid, flexible structure with or without surface loading, the feasibility of the FSI method is verified.
