平衡功能障碍康复训练装置的有限元分析
Finite element analysis on rehabilitation training device for balance dysfunction
摘要
Abstract
BACKGROUND: A rehabilitation training device has been designed by us for the balance dysfunction.OBJECTIVE: To analyze the strength and stiffness of the rehabilitation training device.METHODS: Strength and stiffness analysis was performed using the working interface Workbench of finite element analysis software ANSYS. Five different working conditions were considered. The device's gravity loading and the patient's weight loading were applied on the finite element model under the same constraints. The stress distribution and deformation were gained for the different working conditions.RESULTS AND CONCLUSION: Under the five kinds of conditions, the area of stress concentration and maximum deformation was roughly same, and the values were positive correlated with angle. The maximum equivalent stress was less than the yield limit of material, which means that the strength of rehabilitation training device could meet the requirement of design. In the sight of the maximum stress and deformation, the device's design tended to be conservative, and the weight of the whole device could be reduced through the structure optimization. For a complicated model, the new working interface Workbench of ANSYS had higher efficiency than the Classic interface.关键词
