概括
与直立乘客相比,在倾斜的座位上的肥胖乘客在正面撞击中经历了更大的头部和大腿部位移和潜在的更严重的肋骨损伤. 这项研究有助于为各种车身类型开发更安全的车辆安全系统.
科学领域:
- 生物力学 生物力学
- 职员安全 职员安全 职员安全
- 汽车工程 汽车工程
背景情况:
- 肥胖率的增加需要了解不同姿势的乘客反应.
- 有限的数据存在于肥胖的乘客在正面冲击时倾斜的位置.
研究的目的:
- 在正面冲击中比较头,干和骨盆运动.
- 记录不同坐姿的肥胖乘客的受伤和受伤模式.
主要方法:
- 测试了6名死后人类受试者 (PMHS) 患有肥胖症 (BMI 38.2 ± 5.3 kg/m2).
- 试验对象用三点腰带直立或俯卧 (23°,45°) 进行了测试.
- 撞击是在低速 (15公里/小时) 和中速 (32公里/小时) 的速度进行的.
主要成果:
- 在32公里/小时的速度下,躺着的乘客表现出明显更大的头部 (190毫米对105毫米) 和大腿部 (52毫米对30毫米) 的Z位移.
- 所有中等速度测试都导致胸部受伤;躺卧的乘客有更多的双皮层肋骨骨折,这表明肺胸风险更高.
结论:

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...

196
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.

01:12General Case of Eccentric Axial Loading
202
Unsymmetrical bending occurs when the bending moment applied to a structural member does not align with its principal axis. This misalignment leads to complex stress distributions and deflection patterns that differ from symmetrical bending, which are essential for designing structures to withstand different loading conditions.
Consider a member subjected to equal and opposite forces that are applied along a line that does not coincide with the member's neutral axis. In unsymmetrical...
