螺栓连接强度的正交实验分析
Orthogonal Experimental Analysis of Bolt Connection Strength
摘要: 螺栓连接作为机械装配中常见的连接方式，在工程实践中扮演着重要的角色。螺栓连接的强度直接关系到机械结构的安全性和可靠性。然而，螺栓连接的强度受到多种因素的影响，本文通过对螺栓连接关系进行简化建模，通过ANSYS Workbench对其进行仿真，得到了螺栓的总变形和应力特征。再通过设计正交实验，分析了不同螺栓直径、螺栓预紧力、结合面摩擦系数对螺栓的总变形和等效应力的影响程度，为优化螺栓连接设计提供了参考依据。
Abstract: Bolted connections are a common method of assembly in mechanical engineering and play a vital role in ensuring the safety and reliability of mechanical structures. The strength of a bolted connection is influenced by various factors. This study simplifies the relationship of bolted connections through modeling and uses ANSYS Workbench for simulation to obtain the total deformation and stress characteristics of the bolts. An orthogonal experimental design is employed to analyze the effects of different bolt diameters, bolt preload, and the coefficient of friction at the interface on the total deformation and equivalent stress of the bolts. The findings provide valuable insights for optimizing the design of bolted connections.
