Computer Aided Design of Protective Gear and the Mathematical Statistics for Mechanical Mechanism from Falls

Abstract

Increasing aging population lies great pressure on our country, and the health monitoring of the elderly arises as a very urgent problem to be solved. The elderly's body function is degraded in many aspects, and tumble, a problem elderly people most often encounter, brings unpredictable and serious injury or even leads to life risk behavior to them. In order to reduce the injury caused by falls, it is necessary to design protective devices that conform to the characteristics of the elderly. In this paper, by searching the current status and possible trend of aging population in China, we investigate the accident rate and harm caused by elderly tumble. Consider the head injury of the elderly as an example, a numerical simulation was conducted to analyze the mechanical mechanism of the head injury of the elderly falling. Combining the mechanical mechanism of the head injury, we compared several protective materials and selected the one that optimized our goal of head protection. Therefore, we designed one head-wearing buffering protective device, which is of great significance to the head injury prevention of the elderly falling.
