简述了波纹管结构的特点，以工程应用中最为常见的正弦波和直线波管形为例，通过采用有限元方法对各种参数下管形结构的刚度、应力情况进行分析，为对这些管形结构优化设计提供了依据。
The characteristics of the corrugated pipe structure are briefly described. Taking the most common sine wave and straight pipe shapes in engineering applications as an example, the stiffness and stress of the pipe structure under various parameters are analyzed by using the finite element method. The optimal design of the tubular structure provides the basis.
