Thoracic force-deflection characteristics have been measured in the living little pigs as a step towards the analysis of thoracic injury in the field of forensic medicine. Mechanisms of injury by hand impact with a small stone were investigated by means of high speed video/camera and load cell. Initial velocity by hand impact ranges from 5.8 to 11.1 m/s, with corresponding peak force from 24 to 122 kgf. The thoracic force-deflection of the pig shows a progress change with increasing impact velocity, showing more of a spring-mass like response with an initial linear region of stiffness during a short interval immediately after the impact. Peak force up to 122 kgf was developed for 77 mm in the localized thoracic displacement with rib fractures and serious lung injury. A few rib fractures occurred with initial velocity near 9 m/s and displacement near 50 mm, these data suggest an outbreak limit of rib fractures of the little pig.
作为法医学领域分析胸部损伤的一个步骤，已经对活体小猪的胸部力-位移特性进行了测量。通过高速视频/摄像机和测力传感器研究了用小石块进行手部冲击造成损伤的机制。手部冲击的初始速度范围为5.8至11.1米/秒，相应的峰值力为24至122千克力。猪的胸部力-位移随着冲击速度的增加呈现出渐进变化，在冲击后紧接着的短时间间隔内，在初始线性刚度区域表现出更多类似弹簧-质量的响应。在局部胸部位移77毫米时产生了高达122千克力的峰值力，伴有肋骨骨折和严重的肺损伤。当初始速度接近9米/秒且位移接近50毫米时发生了一些肋骨骨折，这些数据表明了小猪肋骨骨折的爆发极限。
