The Computational Analysis of Rat Training Treadmill Structural Based on the Sensory-Balance-Exercise

目的基于研究开发的脑损伤大鼠感觉功能、平衡功能、运动功能训练一体化的多功能跑台,对其关键部件做计算分析。方法利用三维软件Solid Works建模,有限元前处理软件Gambit做网格划分,有限元软件Ansys做计算与后处理。结果经计算后得知,关键部件的最大应力与最小应力位置分别在倒杆的最下端与最上端,有限元分析得到的两者最大应力值分别为162.47 MPa和87.523 MPa,均小于允许应力值;最大形变值分别为0.744 97 mm和0.679 64 mm,均在材料容许形变范围内。结论通过理论计算与软件模拟对部件分析得出结果,验证设计的实际可行性。

Objective The developed integration multi -function treadmill can be used for training the rats with brain damages for sensory function, balance function, motor function. This study aimed to perform computational analysis on the key parts of the treadmill. Methods 3D software SolidWorks was used to build models, and processor software Gambit was used for meshing, and the finite element software Ansys was applied for calculating and post - processing. Results After calculating, the maximum and minimum stress position of key parts were obtained, which are the down and top of the treadmill. The maximum stress values are 162.47 MPa and 87. 523 MPa, respectively, which are both smaller than allowable stress value. The maximum deformation values are 0. 744 97 mm and 0. 679 64 ram, respectively, which are both in the range of material allowable deformation values. Conclusions The results of the theoretical calculation and software simulation for key parts verify that the design of the treadmill is feasible.
