摘要
In order to study the mechanical response and injury characteristics of living lungs under the action of blast shock waves, this study first established a finite element model of the chest of a small pig and used a newly developed PVDF (polyvinylidene fluoride) flexible pressure sensor to test the surface pressure of animals in shock tube experiments, verifying the accuracy of the finite element model. Secondly, the validated model was used to study the characteristics of lung injury of pigs at different blast distances, analyzing the lung injury location and severity under different intensities of shock waves. Moreover, the relation between the peak pressure on the surface of the chest and the grade of lung injury was established. Finally, blast tests were performed to obtain the lung injury of pigs as well as the chest surface pressure histories at different blast distances, which can be used to verify the correctness of the established relation.
