| 摘 要： | 针对在叶片缘板部位设置干摩擦阻尼块后的叶片减振效果问题,进行理论模型简化后,利用传递矩阵法进行分析计算。为了验证传递矩阵法的计算结果,利用ANSYS有限元程序对缘板干摩擦阻尼叶片减振进行计算。两种计算方法所得结果基本一致,说明适合于链状结构系统的传递矩阵法可以成功应于板状结构系统,且算法与结果均正确。

| Abstract: | A simplified method using transfer matrix method was applied to the analysis and calculation of the vibration damping effect induced by dry friction snubber on the blade platform.To validate the calculated results of the transfer matrix method,the finite element method ANSYS was used to calculate blade vibration with dry friction damper on the platform.The calculated results of the two methods are basically consistent,which demonstrates that the transfer matrix method suitable for chain-construction-system can also be applied to the plate-construction-system. |
