空气冲击波作用下肺部载荷特性数值模拟
Loading characteristics of air shock wave on lung by numerical simulation
摘要
Abstract
Objective The loading characteristics of air shock wave on the lung of rabbit are analyzed, which may provide reference for the evaluation of blast injury and its prevention and treatment. Methods A two-dimensional plane model for the lung of rabbit is established, and its dynamic response to 90 g TNT explosive with a distance of 0.5 m is simulated by ANSYS Autodyn finite element analysis software. Results In the local area where shock wave directly interacts with thorax, pulmonary pressure is covered by the stress wave which is transmitted from the wall-surface compression wave through muscle and bone. The pulmonary pressure in other area is covered by the stress wave which is transmitted from that in the bone. Conclusion The loading characteristics of air shock wave on the lung of rabbit include the direct action of the wall-surface compression wave and the indirect action of the bone deformation, and the reflection from the interface of bone and lung as well as the cavitation effect.关键词
