Abstract

The invention belongs to the technical field of computer modeling, and discloses a human maxillofacial region explosion injury simulation and biomechanical simulation method and system and a medium. The method comprises the following steps: selecting a TNT explosive as an injuring object, taking an explosion target as a left mandibular angle midpoint, establishing a human maxillofacial region anatomical geometrical form through ANSA software, establishing a particle model of the human mandibular and TNT explosives through adoption of a smooth particle dynamics method, setting an explosive particle spacing, and analyzing the influence of explosive shock waves on soft and hard tissues of the human maxillofacial region. According to the method, the injury process and biomechanical characteristics of the human mandibular soft and hard tissue explosion injury are analyzed, the effectiveness of a smooth particle dynamics method in research of the human mandibular soft and hard tissue explosion injury is analyzed, and a new method is provided for a maxillofacial soft and hard tissue explosion injury model. Compared with a finite element research method, the smooth particle dynamics methodhas remarkable advantages in soft and hard maxillofacial tissue blast injuries, and a new method is provided for maxillofacial blast injury model research.

Description

technical field [0001] The invention belongs to the technical field of computer modeling, and in particular relates to a method, system and medium for simulating blast injury of human maxillofacial area and biomechanics. Background technique [0002] At present, explosive weapons are widely used in modern warfare. Due to the lack of protection of the maxillofacial area, the proportion of explosive injuries in the maxillofacial area is relatively high, and the treatment of explosive injuries in the maxillofacial area is difficult, and the injury and death rates are high. Therefore, the establishment of human maxillofacial The focus of maxillofacial combat trauma research is to establish a model of facial soft and hard tissue blast injury and systematically analyze the mechanism, injury characteristics, protection and treatment of maxillofacial blast injury. Three-dimensional finite element method (FEM) can analyze complex mechanical changes between objects and inside objects,...
