Numerical Evaluation of the Effectiveness of the Air Chamber of Shoes Pad for Diabetes with FE-SPH Method

摘要：

　　The object of this study is to utilize FE-SPH method to simulate the dynamic behavior of the air chamber of shoes pad for diabetes during footing process.The shoes pad numerical models are discrete as FE mesh,and the air inside is modeled as SPH particles.The fluid structure interaction analysis between air and the shoes pad is carried out with contact algorithms.This explicit dynamic analysis is run on ANSYS software.Results show that: when the shoes pad is loaded,the velocity field concentrated on the central region of air chamber,and the particles in the fringe maintain a zero speed,which means the air flow out in the central region instead of the fringe.Thus,the shoes pad is effective in supplying air for the foot of diabetes.
