摘要:
以ANSYS有限元软件为工具，通过对齿轮施加预应力来模拟渗碳淬火齿轮的残余压应力。由于残余压应力大小随材料深度而变化，故对轮齿表层进行分层建立，便于各深度层残余压应力的模拟施加，并在相同的载荷工况下，对由渗碳淬火而产生残余压应力齿轮和不存在残余压应力齿轮，分别进行了弯曲强度和弯曲疲劳寿命分析，以研究残余压应力对齿轮弯曲强度以及疲劳寿命的影响作用。通过结果对比分析表明，残余压应力可使齿轮弯曲抗疲劳性能得到提高。
Abstract:
ANSYS finite element software is used as a tool to simulate the compressive residual stress of carburizing and quenching gear by applying prestress to gear. Since the compressive residual stress varies with the depth of material, in order to facilitate the simulation of the compressive residual stress in each layer by layering the surface layer of gear teeth. Under the same load conditions, the compressive residual stress gear produced by carburizing and quenching and the absence of compressive residual stress gear are respectively analyzed for flexural strength and fatigue life, in order to study the compressive residual stress’s influence on flexural strength and fatigue life of gear. The results of the analysis show that the compressive residual stress can make gear flexural fatigue resistance improved
