回顾了降落伞研究方法从实验方法、半经验半理论方法到仿真模拟方法的发展历程,显示了数值模拟方法在降落伞研究方面的巨大前景。同时总结了伞衣流场数值模拟、伞衣结构数值模拟、流场和结构耦合的数值模拟的最新进展,通过研究发现,降落伞流固耦合数值模拟研究的主要方法是任意拉格朗日欧拉方法(ALE)、变空间域/稳定时间-空间(DSD/SST)方法和浸没边界法(IBM),这些方法代表了降落伞流固耦合技术研究的最新水平。
The development course of parachute research methods from experimental methods, semi-empirical semi-theoretical methods to simulation methods is reviewed. The great prospects of the numerical simulation methods in parachute research are also shown. At the same time, the latest progress in numerical simulation of flow field of umbrella canopy, numerical simulation of umbrella canopy structure and numerical simulation of flow field and structure coupling are summarized. It is found through research that the main method of numerical simulation of parachute fluid-solid coupling is Lagrange Eulerian ALE, DSD / SST, and Immersion Boundary (IBM), these methods represent the latest level of research on the parachute’s fluid-solid coupling technology.
