摘要

摘要: 针对新型航空发动机管路连接副,研究了其在安装过程和松动过程中的接触特性。首先,将连接副的安装-松动过程划分为3个阶段,并对这3个阶段的摩擦力和接触压力进行了解析推导,分析了摩擦力和接触压力的变化规律。然后,建立了管路连接副的轴对称有限元模型,并对其进行了非线性瞬态分析。最后,基于施加位移载荷的方法模拟了连接副的安装和松动过程,研究了接触面的滑移量、接触压力、摩擦力和接触压应力的变化规律。同时研究了不同预紧力对连接副接触压应力的影响。结果表明:松动过程在滑移点前后可以分为2个阶段,这2个阶段中接触面的接触特性有明显区别;连接副接触面的接触特性只与接触面参数和预紧力大小相关,与管径、材料等其他因素无关。本文研究的安装与松动过程中接触特性变化规律在工程上可以指导新型管路连接副的设计工作。

Abstract: The contact characterizations of new lock pipeline connection, which is used in aircraft engine, were investigated in the installation and loosening process. Firstly, the entire installation and loosening process was divided into three stages. The friction and contact pressure in the three stages were respectively deduced,and the variation of friction and contact pressure was analyzed. Secondly, the axisymmetric finite element model of pipeline connection was established, and nonlinear transient analysis was made. Finally, the displacement load was applied to the finite element model to simulate the installation and loosening process, and the variations of slippage, connection pressure, friction, and contact stresses were analyzed. Besides, the influences of different preloads on the contact stresses of pipeline connection were studied. The analysis results show that the loosening process can be divided into two stages before and after the sliding point; the contact characterizations of the two stages differ obviously. The contact characterizations of pipeline relate only to the parameters of contact surface and the value of preload, but not to the radius of pipeline, materials or any other thing. The variation of contact characterizations of the installation and loosening process can be applied to the pipeline connection designing.
