Children, small female, elderly, and obese occupants are at greater risk of death and serious injuries in motor-vehicle crashes than the mid-size, young, male occupants. However, current injury assessment tools, including crash test dummies and finite element (FE) human models, generally do not account for different body shape and composition variations among the population. The opportunity to broaden crash protection encompassing all vehicle occupants lies in improved, parametric human FE models that represent a wide range of human attributes. In this study, a literature review demonstrates that recent studies on human anthropometry, finite element human modeling, mesh morphing, human tissue tests and whole-body cadaver tests have laid the groundwork for the new generation of human models. A framework for developing such models was proposed in this study. The developed models enable population-based simulations for future vehicle design optimizations targeting at various vulnerable populations that are not represented by current injury assessment tools.%在汽车碰撞中,相对于平均身高的年轻男性,儿童、矮小女性、老人和肥胖者是易受伤害的人群,因而会有较高的死亡率和重伤率。但包括碰撞假人和人体有限元模型在内的现有伤害评价工具,一般未考虑人群中体型和身材组成的多样性。参数化人体有限元模型能够代表广泛人体属性,最大地拓宽碰撞安全所保护的人群。本综述发现:关于人体测量学、人体有限元模型、网格变换、人体材料试验和尸体试验的最新研究,为建立参数化人体有限元模型奠定了基础。本文提出了建立这样一个参数化的人体有限元模型的方案。该模型可模拟不同人群,对汽车进行安全优化设计,这是现有伤害评价工具所无法做到的。
