Abstract
A high number of slip-and-fall incidents result in common injuries of daily life. The design of outsole tread pattern is one of the key factors which had a direct impact on slip resistance performance. The application of numerical simulation is an opportunity for footwear industry to evaluate the multiple outsole tread pattern design and ground condition in a more controlled and efficient manner than mechanical testing in the developing process.
A complex three-dimensional (3D) FE model of the shoe was developed to evaluate the effect of outsole tread pattern design on slip resistance performance during the gait motion. The dynamic plantar pressure distributions were automatically applied as the loading condition in FE model which allowed to interpret the individualized subject condition.
The herringbone tread design and higher real contact area between shoe and ground could achieve better slip resistance performance. The process of this study demonstrates the potential of numerical simulation for evaluating slip resistance performance.
