In the project, a database with information of morphology, physical charac-teristics and physiological function will be constructed. The raw data of CDH which was completed in the Southern Medical University is employed. In Huazhong University of Science and Technology (HUST), the frozen section images are preprocessed, segmented, labeled in accordance with the major organs and tissues of human beings, and reconstructed into three-dimensional (3D) models in parallel on high performance computing clusters (HPC). Some visualization software for 2D atlas and 3D mod-els are developed based on the new dataset with high resolution (0.1mm×0.1mm×0.2mm). In order to share, release and popularize the above work, a website (www.vch.org.cn) is online. The dataset is one of the most important parts in the national information database and the medical infrastructure.展开更多
在近年来发生的几场局部战争中,地雷及简易爆炸物造成了大量人员伤亡。为了解车辆底部爆炸条件下车内乘员的损伤特点,构建了包含乘员、车体结构及爆炸流场的仿真模型,研究了车辆乘员身体主要部位损伤风险。利用LS-DYNA的流固耦合算法求...在近年来发生的几场局部战争中,地雷及简易爆炸物造成了大量人员伤亡。为了解车辆底部爆炸条件下车内乘员的损伤特点,构建了包含乘员、车体结构及爆炸流场的仿真模型,研究了车辆乘员身体主要部位损伤风险。利用LS-DYNA的流固耦合算法求解爆炸流场与车体结构的相互作用,分析了爆炸冲击的传递路径及乘员典型运动姿态。基于人体有限元模型,以6 kg及8 kg TNT 2个爆炸当量工况为研究对象,对车辆乘员头部、脊椎、骨盆及下肢等身体部位进行损伤风险评估。仿真结果表明:对于佩戴安全带的乘员,其足踝部及胫腓骨损伤的风险最高,其次为骨盆及胸腰椎。研究结果可为车辆防护设计提供参考,从而提高乘员安全性。展开更多
