摘　　要：齿轮齿条是齿轮齿条式转向器工作过程中力和力矩承载的关键部件,其刚度条件是转向器设计的重要基准。针对轮齿齿条式转向器的力学性能,文章运用Catia建立了齿轮齿条三维实体模型,随后利用HyperMesh进行网格划分,最后导入Abaqus进行有限元计算。分析结果表明:齿轮的最大应力189.2MPa,齿条的最大应力为86.59MPa,齿轮和齿条的应力均满足强度要求。The rack and pinion is the key part of the load-bearing of force and moment in the working process of the pinionand-rack steering gear.Their rigidity conditions are important benchmark for steering gear design.In view of the mechanical properties,this paper uses CATIA to establish a three-dimensional solid model of the gear.Then,the HyperMesh code is employed for meshing.Finally the Abaqus is applied to carry out the finite element calculation.The results show that the maximum stress of the rack is 189.2Mpa,86.59Mpa for the pinion.The stress of pinion-and-rack steering meets the strength requirement.
