摘要
Abstract
In response to the physical mechanism and vulnerable areas unknown of lung injury caused by blast shock,we employed the numerical simulation study on the mechanical response of human lung under the action of blast shock.Firstly,a finite element mod-el of the human chest was established.Then,based on the numerical simulation method,the finite element numerical analysis software LS-DYNA was used to study the pressure evolution law of the explosion flow field,the mechanical response of the chest cavity and the stress distribution law of the lung after the shock wave.The results showed that under blast loading,the chest wall collided at high speed with the thoracic organs,and the compression wave was generated in the lung.The transient pressure of the lung was the main mechanism of lung injury.Under the action of shock wave,the lung tissue near the ribs,heart and vertebrae was more prone to injury.Shear stress formed between the ribs'edge and the lung tissue was a key factor in the development of streak hemorrhage.The research verifies the validity of the chest model and can reveal the mechanical mechanism of blast shock waves causing lung injury.关键词
