摘　　要：锥形接头是发动机管路连接中常用的一种结构。针对不同尺寸参数的锥形接头密封效果不同的问题,该文首先建立了锥形接头物理模型,然后采用数值计算的方法对74°锥角的锥形接头的密封特性进行了研究;为了获得锥形接头锥角的最优设计参数,采用响应面模型与多目标遗传优化算法相结合的方法对锥形密封接头的锥角进行了优化。结果表明:阳端头锥角为74.4°,阴端头锥角为74.2°时管路锥形接头的密封效果最佳。The conical joint is a commonly used structure in engine line connections,and the sealing effect of conical joints with different size parameters varies.First of all,the physical model is established,and then the sealing characteristics of the tapered joint with 74°cone angle are studied by numerical calculation in order to obtain the optimal design parameters of the tapered joint cone angle.Finally,the response surface model and multi-objective genetic optimization algorithm are used to optimize the taper angle of the tapered sealing joint.The results show that the sealing effect is best when the conical joint angle of the positive end is 74.4°,and the cone angle of the negative end is 74.2°.
