利用有限元数值计算与解析分析相结合的方法，通过对带间隙的拱型构件的振动分析，研究了拱型结构件在两端约束存在间隙时的扭弯耦合非线性振动特性，提出了数值解析法，并得到满意的结果，从而为解决此类问题提供了一条新途径
Based on the vibration analysis of the arched component with gap, the nonlinear vibration characteristics of the torsional and torsional coupling of the arched component under the constraint of the two ends are studied by means of the combination of finite element numerical analysis and analytical analysis. The numerical results Analytical method, and get satisfactory results, thus providing a new way to solve such problems
