摘要

本研究的目的是评估肥胖人体模型（HBM）在额橇测试中的行为。肥胖（BMI=35）死后人类代孕者（PMHS）的后座雪橇测试结果用于评估肥胖HBM在匹配条件下的表现。此外，在前排座椅正面碰撞测试中比较了非肥胖HBM（BMI=25）和肥胖HBM的反应。在后排座椅测试中，肥胖的HBM和肥胖的PMHS在整个测试过程中都经历了大的向前偏移、腰带与骨盆的接合延迟以及躯干倾斜到直立的角度，这是大体重和厚肉的影响。在前排座椅模拟中，肥胖HBM比非肥胖HBM经历了更大的偏移。肥胖HBM可以成为设计和优化肥胖前排座椅乘客约束系统的有用工具。

Evaluation of behaviour of an obese human body model in frontal sled tests

The goal of this study was to assess the behaviour of an obese Human Body Model (HBM) in frontal sled tests. The results of rear-seat sled tests with an obese (BMI = 35) Post Mortem Human Surrogate (PMHS) were used to evaluate the performance of the obese HBM in matching conditions. Also, the responses of a non-obese HBM (BMI = 25) and the obese HBM were compared in a front-seat frontal impact test. In the rear-seat tests, both the obese HBM and the obese PMHS experienced a large forward excursion, delayed lap belt engagement with the pelvis, and a reclined-to-upright torso angle throughout the tests, which were the effects of large body mass and thick flesh. In the front-seat simulations, the obese HBM experienced a larger excursion than the non-obese HBM. The obese HBM can be a useful tool to design and optimise restraint system for front-seat occupants with obesity.

期刊介绍： The IJVS aims to provide a refereed and authoritative source of information in the field of vehicle safety design, research, and development. It serves applied scientists, engineers, policy makers and safety advocates with a platform to develop, promote, and coordinate the science, technology and practice of vehicle safety. IJVS also seeks to establish channels of communication between industry and academy, industry and government in the field of vehicle safety. IJVS is published quarterly. It covers the subjects of passive and active safety in road traffic as well as traffic related public health issues, from impact biomechanics to vehicle crashworthiness, and from crash avoidance to intelligent highway systems.
