【摘要】 将悬挂结构简化为串并联模型,建立考虑节点转动的一致刚度矩阵和一致质量矩阵建立结构的总刚度矩阵和总质量矩阵,通过简化得到结构的竖向刚度矩阵和相应的质量矩阵,并进行了竖向振动下的模态分析,从中得出了悬挂结构竖向振动的一些特征与结论。更多还原

【Abstract】 In this paper,the suspended structure has been simplified to the series-parallel-connection model.The consistent-stiffness matrix and consistent-mass matrix also have been established which considered joint rotation.After predigesting the stiffness matrix and mass matrix,the vertical stiffness matrix and mass matrix have been obtained.There has been vertical vibrational mode analysis on the model.From the result of analysis some characters and conclusions of suspended structure under vertical vibration have been obtained.更多还原
