| Abstract (English): |
The key and difficult points of forensic analysis of high-falling cases are to infer and reconstruct human falling trajectory and analyze the formation mechanism of injury. These results help to provide technical support for the comprehensive judgment of the nature of human fall, and help to provide intuitive and effective explanations for non-professionals such as family members of the deceased. Numerical simulation technology is a series of new interdisciplinary technology formed on the basis of the continuous development of computer simulation. In recent years, thanks to the development of numerical calculation methods and the improvement of computer performance, the technology has made some progress in the research field of damage biomechanics. Numerical simulation technology has advantages of objectification, visualization, parameterization and repeatability of simulation results. This technique opens up a new way to analyze and study the fall process and fall damage in high-falling cases. Based on this kind of technology, the simulation analysis of human falling trajectory and falling damage is conducive to more scientific, objective and understandable analysis conclusions, so as to provide important technical support for judging the nature of high-falling cases, answering questions of family members and resolving social conflicts. There are two kinds of numerical simulation techniques suitable for high falls. One is to analyze and reconstruct the falling process based on the multi-rigid body dynamics method. Another is to analyze the formation mechanism of falling damage based on the finite element method. This paper reviewed the application of numerical simulation technology in high falling cases at home and abroad in recent years, and showed the application potential of this technology in the forensic analysis of high fall cases.

| Abstract (Chinese): |
高坠案的焦点、难点是推演重建坠落轨迹，分析损伤机制，为综合判断坠落性质提供依据，并将结论 向死者家属等非专业人士进行直观、有效的解释。近年来,得益于数值运算方法发展和计算能力提高等有利条件， 数值模拟技术在损伤生物力学研究领域取得了一定进展。该技术具有模拟结果客观化、直观化、参数化以及可 重复等优势，为分析研究人体坠落轨迹及坠落伤等开辟了新的途径。高坠数值模拟技术主要有两种方法，一种 是基于多刚体动力学方法进行坠落轨迹的推演重建；另一种是基于有限元方法进行坠落伤的推演重建。本文综 述了近年来国内外数值模拟技术在高坠案中的应用研究，展示了该技术应用于高坠案法医分析的潜力。 [ABSTRACT FROM AUTHOR] |
