Development of a test system for evaluation of hip protectors to prevent hip fracture

阐述了髋关节跌倒骨折的机理以及髋关节保护器对髋部骨折的保护作用，为研制髋关节保护器的测试系统奠定了基础。在此基础上，设计并制作了保护器测试系统，并对自行研制的保护器和市场上销售的几种保护器进行了评估。除此之外，我们还对臀部跌倒导致髋部骨折的风险进行了分析，发现臀部跌倒可能比行走时跌倒更危险。为了得到准确的模拟结果，我们还观察和组织了我们对肌肉骨骼肌损伤特性的实验结果，并制定了肌肉的本构模型。

The mechanism of hip fracture by fall and the effects of hip protector on the protection of hip fracture are elucidated for developing a test system to evaluate a hip protector. Based on the results, we design and manufacture the test system, and evaluate a protector developed by us, and a few protectors commercially available in the marketplace. In addition to these, we perform the analysis to evaluate the risk of hip fracture by backside fall, and find that the backside fall may be more dangerous than the fall under walking. To obtain accurate simulation results we also observe and organize our experimental results on damage properties of musculoskeletal muscle, and formulate constitutive models of the muscle.
