Finite Element Analysis, Knee Protector, Stress, Garment DesignAbstract
At present, the skateboard protective equipment on the market has many shortcomings: on the one hand, most of the protective equipment are independently worn, which are separated from trousers, which is not only inconvenient to wear, but also easy to shift during exercise; On the other hand, the selection of cushioning materials and thickness design of existing protective devices lack scientific analysis and rely more on experience, or the movement flexibility is affected by the thick and hard materials, so the balance of protection, flexibility and comfort cannot be achieved. Based on this, this study focused on the pain points of knee injury protection in skateboarding, and carried out the design research of protective skateboarding pants. Firstly, the finite element model of knee joint under three typical fall conditions, kneeling, lateral and prone, was constructed based on the THUMS manikin, and the stress distribution characteristics of knee joint bones under different impact speeds were revealed. Secondly, the quantitative relationship model between material thickness and stress attenuation is established through finite element simulation, and the high energy absorbing material and its optimal thickness configuration are selected. The results show that EVA material has the best stress attenuation effect; 9-12 mm is the best thickness range for both protection and comfort. Finally, a kind of protective skateboard pants with detachable panda pattern protector was developed. This research not only has practicability, but also can promote the interdisciplinary and integration, and provide new ideas and methods for the research of other sports protection, medical rehabilitation and safety fields, especially in the field of protective and functional clothing, such as racing clothes and extreme sports clothes, which has application prospects and innovation value.
