摘要
轴系不对中是旋转机械常见的故障，通过对该故障建立理论模型，并采用 Ｒａｃｃａｔｉ传递矩阵法对之进行数值计算和理论分析，重点计算了角度不对中时的振动特性。为旋转机械的故障诊断提供理论参考。
Misalignment of shaft system is a malfunction which frequently occurs in the rotating machinery. This paper develops a reasonable misalignment model and employs the Raccatti transfer matrix method to calculate the vibration characteristics on misalignment with desirable results, which can be used for reference in the prevention and diagnosis of misalignment default.
