摘　　要：波形弹簧作为航空密封组件中的一个重要零件,其力学性能对密封组件性能影响很大。在实际制造和使用过程中存在设计特性与实际特性相差较大、缺少有效可靠理论指导等问题。本文对航空密封组件中作为精密弹性元件的波形弹簧力学性能进行了研究,包括理论计算、有限元分析等内容,改进了波形弹簧轴向受力及变形计算方法,进行了实际测试和试验验证,有效提高了波形弹簧的设计计算精度。As an important part of the aviation sealing, mechanical properties of the wave spring have a great influence on properties of the aviation sealing. In the actual manufacture and use of the process exist such problems, design characteristics and product characteristics of actual measurement is different, lack of effective and reliable theoretical guidance. In this paper, mechanical properties of the wave spring as a precision elastic element in the aviation sealing are studied, including the theoretical calculation, finite element analysis. The paper improved the wave spring axial deformation calculation method under axial force, and obtained the actual test and the test verification, finally effectively improved the precision of the wave spring design and calcu- lation.
