摘　　要：对预紧状态下的连杆应力分析仿真方法进行研究。在分析连杆应力时考虑预紧效应,探究和对比温差法和预紧单元法这2种预紧仿真方法,用有限元方法对预紧状态下的连杆进行数值分析;并分析连杆在2种工况下的应力分布,叠加预紧和特殊工况下的应力值得到应力幅和平均应力。研究结果将为连杆有限元分析中施加预紧力载荷提供可靠的理论和应用依据。Considers the preload effect in the analysis of the stress of the connecting rod, and use two kinds of pre tightening simulation method, temperature difference method and pre-tightening element method, to study the simulation methods. The finite element method is used to analyze the connecting rod in the pre-tightening condition, and the stress distribution of the connecting rod under two conditions is analyzed. The stress amplitude and the average stress are obtained by superimposing the stress under preloading and the special conditions. The research results will provide a reliable theory and application basis for the application of preload in the finite element analysis of connecting rod.
