Interface failure analysis and robust design method in rotor structural system

摘要

摘要: 针对结构非连续转子中连接界面接触状态变化引起界面力学特征改变,使转子系统动力特性不稳健的问题进行分析,并提出了一种界面接触状态的稳健设计方法。结果表明：该方法通过分析结构非连续转子系统中界面损伤失效的力学过程,对结构特征参数进行优化设计,降低界面力学特性对载荷环境的敏感度。以涡轮转子套齿连接为例进行优化设计得到,在加工装配误差所导致的应力极限情况下,最优解的接触应力水平更加远离应力约束边界,使带有连接界面的结构非连续转子系统的力学特性更加稳健,具有较好的工程应用价值。

Abstract: For the contact status variation of mechanical interface making mechanical properties vary in rotors with non-straight structures, the non-robust problem of rotor systems dynamics characteristic was analyzed, and a novel robust design method of contact status was presented. Result showed that this method analyzed the damage and failure process of mechanical interface in non-straight structural rotor system structural properties optimal design, and established an optimal design for structural properties. This method decreased the sensitivity of mechanical properties under loads and environment. An optimal design of the spline coupling structure in turbine rotor was implemented. The results indicated that the contact stress of optimal solution kept far from stress-constrained boundary under the condition of manufacturing errors. The mechanical properties of non-straight structural rotor system with mechanical interface were more robust than before. The robust design method of mechanical interface shows preferable engineering value.
