标准摘要
[中文适用范围]： CRABI 假人的开发目的是评估汽车碰撞环境中的小型儿童约束系统@在所有冲击方向@有或没有安全气囊相互作用。该测试设备的基本人体测量取自密歇根大学交通研究所报告 85-23。婴儿的体重分布和缩放方法得到了汽车协会 (SAE) 婴儿假人任务组的批准。该假人重 17.2 磅，站立高度为 26.4 英寸，坐高为 17.3 英寸。类似 Hybrid Ill 的颈部和腰椎有横向凹口，以减少横向刚度。肩部有肌肉支撑，可在可能放置安全带的区域提供耐用性和类似人类的性能。此外，每个关节均使用橡胶元件，以提高生物保真度并赋予 CRABI 婴儿般的运动范围。 CRABI 六个月大的设计满足所有 SAE 婴儿假人任务组人体测量@生物力学和仪器要求。仪器设计包含三个 6 通道称重传感器，可在 C1@ C7 和 L5 椎骨位置提供负载测量。加速度计用于测量头部@胸部和骨盆加速度以及头部角加速度。所有仪器均可轻松访问 [外文原描述]： The CRABI dummy was developed to evaluate small child restraint systems in automotive crash environments, in all directions of impact, with or without air bag interactionBasic anthropometry for this test device was taken from the University of Michigan Transportation Research Institute Report 85-23. Weight distribution and scaling methods for the infant were approved by the Society of Automotive (SAE) Infant Dummy Task Group. The dummy weighs 17.2 pounds and has a 26.4 inches standing or 17.3 inches sitting height. The Hybrid Ill-like neck and lumbar spine are laterally notched to reduce lateral stiffnessThe shoulders have flesh support for durability and human-like performance in areas where seatbelt webbing may be placed. In addition, rubber elements are used in each joint to improve biofidelity and to give the CRABI infant-like range of motion. The CRABI Six-Month-Old design meets all the SAE Infant Dummy Task Group anthropometry, biomechanical and instrumentation requirements. The instrumentation design incorporates three 6-channel load cells to provide load measurements at the C1, C7 and L5 vertebrae locations. Accelerometers are used to measure head, chest and pelvic acceleration and head angular acceleration. All instrumentation is easily accessedCross Reference:
