概括
试验人形THOR-50M-RS准确地模拟了坐卧座椅上的乘客姿势. 然而,高速撞击揭示了潜在的胸部和脊椎损伤,突出了躺着乘客保护方面的挑战.
科学领域:
- 生物机械工程 生物机械工程
- 汽车安全 汽车安全
- 人类因素工程 人类因素工程
背景情况:
- 评估先进的碰撞测试人形对于了解乘客保护至关重要.
- 倾斜座椅对安全系统的设计和性能构成了独特的挑战.
- 修改了THOR-50M-RS (人类乘客研究的测试设备 - 第50个男性 - 倾斜座位) 进行倾斜姿势评估.
研究的目的:
- 评估修改后的THOR-50M-RS在倾斜座位条件下模拟现实的姿势和反应的性能.
- 为了比较THOR-50M-RS的动态反应与在相同的躺下条件下的死后人类受试者 (PMHS) 数据.
- 识别与卧式乘客保护相关的潜在伤害风险和动力学挑战.
主要方法:
- 在45度的座椅背部角度使用THOR-50M-RS进行了九次正面雪测试.
- 多种测试条件包括delta V (32公里/小时和50公里/小时) 和安全带负载限制器 (LL) 的力量 (4.5kN和2.7kN).
- 利用多个摄像头和优先级仪器直接与PMHS数据进行比较,使用相关性和分析 (CORA) 进行动态量化.
主要成果:
- 在倾斜座椅模拟中,THOR-50M-RS表现出良好的可重复性,并满足了目标姿势.
- 耐用性问题是轻微的,并得到解决,的响应通常与PMHS动力信号保持一致.
- 相关性得分 (CORA) 不同,表明在精确匹配狭窄的PMHS动力走廊方面存在挑战.
结论:
- 托尔-50M-RS有效模拟躺着乘客的姿势,并显示可靠的可重复性.
- 较高速度 (50公里/小时) 的测试表明,胸部和腰椎损伤的测量超过了为非俯卧姿势设计的限制.
- 这些发现强调了为坐卧式座位乘客开发有效安全系统的复杂性.

Assessment of Respiration
The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...

Anatomical Positions
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Normal and Tangetial Components: Problem Solving
Consider a man with a mass of 70 kg seated in a chair connected to a pin support through a member BC. If the man maintains an upright position, the task is to determine the horizontal and vertical reactions of the chair on the man when the member makes a 45° angle with the horizontal. At this moment, the man has a speed of 5 m/s, increasing at a rate of 1 m/s².
