EOD防护服穿戴者的界面载荷建模
Modeling of Interface Loads for EOD Suit Wearers
摘要：
爆炸物处理（EOD）服被广泛用于保护人类操作员执行紧急任务，如炸弹处理和中和。目前的服装设计仍然需要改进的穿着舒适性，这可以评估的基础上的相互作用力的人-服装接触区域。本文介绍了一种基于仿真的建模框架，计算在人-服界面的交互负载的基础上，穿着者的运动学运动数据。所提出的建模框架包括三个主要组成部分：a）EOD服的惯性和几何建模，b）穿戴者在服内运动的状态估计，以及c）逆动力学分析，以基于模拟的人服模型和估计的人体运动数据来计算人服界面力。这种基于仿真的建模方法可以用来补充实验测试，以提高时间和成本效益的爆炸物处理服评估。在三个不同的人类任务（每个有三个试验），通过比较预测的界面力与商业压力传感器测量的准确性的模拟接口负载的实验基准。
英文摘要：
Explosive Ordnance Disposal (EOD) suits are widely used to protect human operators to execute emergency tasks such as bomb disposal and neutralization. Current suit designs still need to be improved in terms of wearer comfort, which can be assessed based on the interaction forces at the human-suit contact regions. This paper introduces a simulation-based modeling framework that computes the interaction loads at the human-suit interface based on a wearer's kinematic movement data. The proposed modeling framework consists of three primary components: a) inertial and geometric modeling of the EOD suit, b) state estimation of the wearer's in-suit movement, and c) inverse dynamics analysis to calculate the human-suit interface forces based on the simulated human-suit model and the estimated human movement data. This simulation-based modeling method could be used to complement experimental testing for improving the time and cost efficiency of EOD suit evaluation. The accuracy of the simulated interface load was experimentally benchmarked during three different human tasks (each with three trials), by comparing the predicted interface forces with that measured by commercial pressure sensors.
