摘　　要：六角螺栓作为轮边减速器与电动叉车车轮之间的重要连接件,承受着预紧载荷及较大的外载荷,极易变形或断裂,导致减速器工作失效。采用Pro/E软件创建了六角螺栓的三维模型,将三维模型导入ANSYS软件进行静力学计算,随后针对计算结果进行分析,并对不满足力学性能使用要求的工况展开优化。对比更换螺栓材料、增加调整垫、优化螺栓结构三种不同的优化方案,发现优化螺栓结构可以彻底解决六角螺栓变形及断裂失效的问题。对轮边减速器六角螺栓进行ANSYS静力学分析及优化,既可以缩短六角螺栓的设计周期,降低生产成本,又能够延长减速器的工作寿命,提升电动叉车的工作稳定性。Hexagonal bolts serve as critical connectors between the wheel hub reducer and electric forklift wheels.They bear pre-tightening loads and significant external loads,making them highly susceptible to deformation or fracture,which can lead to reducer failure.A 3D model of the hexagonal bolt was created using Pro/E software and the model wasimported into ANSYS softwarefor static analysis.An analysis was then conducted based on the results,and optimal solutions were developed for operating conditions that did not meet mechanical performance requirements.By comparing three optimization approaches:changing bolt materials,adding adjustment pads,and optimizing bolt structures,it was found that optimizing the bolt structure can completely resolve deformation and fracture failures of the hexagonal bolts.Conducting static analysis and optimization of wheel hub reducer hexagonal bolts using ANSYS can shorten the bolt design cycle,reduce production costs,extend the reducer’s service life,and enhance the operational stability of electric forklifts.
