Analysis and Optimization of Rehabilitation Weight-loss Walking Training Vehicle Frame Based on SolidWorks

康复减重步行训练车(后文简称减重车)是一种辅助下肢步行障碍患者进行步态康复训练的设备,其机架设计的合理性和可靠性有待研究。通过SolidWorks对减重车机架进行参数化建模,运用Simulation插件对模型进行仿真分析,随后对减重车机架模型进行优化设计,计算以焊缝屈服应力安全系数为约束条件的机架型钢横截面厚度的最优尺寸。最后,对比减重车试验测试结果与仿真分析结果,验证了优化设计和分析的正确性和有效性。该方法可在设计初期得出最优解,为减重车机架结构分析和优化提供了一种新方法。

The rehabilitation weight-loss walking training vehicle(hereinafter referred to as the weight-loss vehicle)is a kind of equipment to assist the patients with lower extremity walking disorder to carry out gait rehabilitation training.The rationality and reliability of its frame design need to be studied.Through SolidWorks,the parametric model of the frame is built,and the simulation plug-in is used to simulate and analyze the model.Then,the frame model is optimized,and the optimal size of the cross-section thickness of the frame steel with the safety factor of the weld yield stress as the constraint is calculated.Finally,the correctness and validity of the optimization design and analysis are verified by comparing the test results and simulation analysis results of the vehicle.This method can get the optimal solution in the early stage of design,which provides a new method for the structure analysis and optimization of the frame of the weight reducing car.
