摘　　要：为了实现智能轮椅多形态背部支起机构稳定和安全运行,本团队对各种形式角度调节机构进行研究、分析,提出轮椅的背部支起机构使用电动推杆来进行角度调节。搭建了背部支起机构模型,在分析了背部支起机构几何关系和力学模型的基础上,使用MATLAB求解电动推杆固定位置的最优解;借助SolidWorks Motion进行动力学仿真,确定电动推杆的最佳行程。借助SolidWorks Simulation进行有限元仿真分析,验证背部支起机构的设计方案。仿真结果表明:电动推杆的固定位置和行程选择合理,降低了承载梁的载荷,提高了背部支起机构安全性和平稳性。In order to realize the stable and safe operation of multi-modal back support mechanism of intelligent wheelchair,the research group studies and analyzes various forms of angle adjustment mechanism,and proposes that the back support mechanism of wheelchair uses electric push rod to adjust the angle.The back supporting mechanism model is built.Based on the analysis of the geometric relationship and mechanical model of the back supporting mechanism,the optimal solution of the fixed position of the electric push rod is solved by using MATLAB;the optimal stroke of the electric push rod is determined by dynamic simulation with Solidworks motion.With the help of SolidWorks simulation,the finite element simulation analysis is carried out to verify the design scheme of the back support mechanism.The simulation results show that the fixed position and stroke of the electric push rod are reasonable,the load of the bearing beam is reduced,and the safety and stability of the back support mechanism are improved.
