摘要
从理论上讨论了一端固支弹性矩形薄板自由振动频率的求解问题。在MSC.Patran中建立复合材料层合板的有限元分析模型,用MSC.Nastran计算得到自由振动的固有频率和基本振型,结果与试验数据对比,吻合很好,说明采取的数值仿真方法可用于工程设计计算。
The problem of free vibration of elastic rectangular thin plate with one edge fixed is discussed theoretically. Then ,finite element model composite laminates is established using MSC. Patran and the natural frequency and mode of free vibration are obtained by the MSC.Nastran. It is accordant between numerical simulation and test results. The numerical simulation method can be used in engineering design analysis.
