摘　　要：在持刀砍击案件中,如何利用现场勘验调查信息,按照成伤规律与损伤机制,科学逆向溯源成伤行为过程、逻辑关联关键要素、系统构建成伤证据体系,是犯罪调查人员长期面临的难题。本文结合实际案例,梳理砍击成伤的生物力学要素,如伤人过程行为动力学、被害人组织损伤特征,提出使用生物力学、有限元仿真的方法,探索伤人行为的生物力学机制和重建分析关键技术方法。利用此研究成果将突破犯罪现场动态化数据重建的技术瓶颈,帮助案件侦办人员科学及时精准破案。When cases occur from knife slashing and chopping,criminal investigators are always puzzled about how to reappear the process of injuring actions scientifi cally and retroactively because such an endeavor will bring forward the systematic evidence of injury.Usually,the investigators will have extruded the injury mechanism and regularity by analyzing the key logic elements based on the survey information from the crime scene.Through real cases being combined,this paper tries to analyze the biomechanical factors in occurrence of slashing and chopping,with inclusion of the behavioral dynamics during injuring actions and the characteristic injury from victim’s tissue/organ,thereby building up the biomechanics and finite element approach to explore the biomechanical mechanism of injuring actions and the key reconstructive technologies.Such an established approach will likely break through the technological bottleneck about reconstructing a data-dynamic crime scene,helping the criminal investigators accurately solve cases scientifi cally and timely.
