本文利用CiteSpace可视化软件对CNKI和ISI Web of Science数据库所收录的有限元技术在法医学中应用的研究文献进行统计和可视化对比分析,得出国内外法医领域有限元应用研究文献的关键词、机构合作、作者合作的可视化知识图谱.在此基础上,作者对文献内容进行深入研究,发现有限元技术在法医学中的研究及应用主要集中在损伤机制分析方面,以车祸损伤、高坠损伤、钝器损伤、锐器损伤、枪弹损伤等为重点,研究方法主要是通过对人体、致伤物等建立高仿真模型,利用有限元技术,以数字化、可视化、可量化的方式研究各类损伤的生物力学机制.目前,国内外法医学者主要借助Mimics等软件将人体影像数据转换为分割化的三维模型,依托较为成熟的THUMS、ANSYS等有限元系统构建多种损伤模型,有效揭示了各类损伤的发生机制,在一定程度上推动了法医病理损伤专业的发展,为法医学者开展相关研究提供了参考和借鉴.同时,有限元技术在法医学中的应用属于学科交叉,但目前的研究人员多以法医为主,缺少相关学科专业技术人员的深度介入,在某种程度上限制了该技术在法医学中的应用发展,有必要加强与从事有限元等相关研究的专业技术人员之间的交流合作.
Research and Application Analysis of Finite Element Technology Based on CiteSpace in Forensic Medicine
CiteSpace visualization software was used in this article to conduct statistical and visual comparative analysis on the research literature on the application of finite element technology in forensic medicine,which was included in CNKI and ISI Web of Science databases.The key words,institutional cooperation,and author collaboration visualization knowledge graphs of the research literature on finite element application in the field of forensic medicine both domestically and internationally were obtained.On this basis,the author conducted in-depth research on the literature content and found that the research and application of finite element technology in forensic medicine mainly concentrated on the analysis of injury mechanisms,focusing on car accident injuries,high fall injuries,blunt instrument injuries,sharp instrument injuries,bullet injuries,etc.The research method was mainly to establish a high simulation model for the human body,injury objects finite element technology to study the biomechanical mechanisms of various injuries in a digital,visual and quantifiable manner.At present,domestic and foreign forensic scholars mainly use software such as Mimics to convert human image data into segmented 3D models,and rely on mature finite element systems such as THUMS and ANSYS to construct various injury models,effectively revealing the mechanisms of various injuries and promoting the development of forensic pathology injury to a certain extent,providing reference for forensic scholars to carry out related research.At the same time,the author also found that the application of finite element technology in forensic science belonged to interdisciplinary fields.However,current researchers are mostly focused on forensic medicine,and there is a lack of deep intervention from relevant professional and technical personnel,which to some extent limits the application and development of this technology in forensic science.In future research,it is necessary to strengthen communication and cooperation with professional and technical personnel engaged in finite element and other related research.
