摘要

本研究调查了工伤事故中物体坠落造成头部伤害（特别是脑震荡）的风险。案例研究的重点是一名建筑工人，尽管他戴着防护头盔，但头部仍然受伤。利用有限元（FE）分析，对安全帽-头部系统进行建模，以评估冲击力和头部加速度。该安全帽由高密度聚乙烯制成，配有 6 点悬挂系统，针对重量为 332 克和 665 克的坠落物体进行了测试。从 5 米至 25 米的高度进行的模拟显示，重量仅为 332 克的物体从 10 米高处坠落会造成严重脑震荡。这些研究结果表明，头盔虽然可以减轻一些冲击力，但其吸收的能量远远低于坠落物体的动能。分析结果证实了这名工人的说法，即他的受伤是由于有头盔保护的头部受到异物坠落造成的。

Evaluating protective helmet efficacy in work-related accident: A forensic biomechanical analysis of concussion risk from falling objects

This study investigates the risk of head injuries, specifically concussions, from falling objects in workplace accidents. A case study focuses on a construction worker who sustained a head injury despite wearing a protective helmet. Utilizing finite element (FE) analysis, the helmet-head system was modeled to assess impact forces and head accelerations. The helmet, made of High-Density Polyethylene with a 6-point suspension system, was tested against falling objects of 332 g and 665 g. Simulations, conducted from heights of 5 to 25 m, revealed that objects weighing as little as 332 g could cause severe concussions from a 10-meter fall. These findings demonstrate that helmets, while mitigating some impact, absorb significantly less energy than the kinetic energy of falling objects. The analyses carried out confirmed the worker’s statement that his injury was caused by a foreign object falling on his head, which was protected by a helmet.

期刊介绍： Legal Medicine provides an international forum for the publication of original articles, reviews and correspondence on subjects that cover practical and theoretical areas of interest relating to the wide range of legal medicine. Subjects covered include forensic pathology, toxicology, odontology, anthropology, criminalistics, immunochemistry, hemogenetics and forensic aspects of biological science with emphasis on DNA analysis and molecular biology. Submissions dealing with medicolegal problems such as malpractice, insurance, child abuse or ethics in medical practice are also acceptable.
