# matrix arithmetics meaning in Chinese

## Examples

1. fist ly, use mass equivalent method to predigest the original rotor system . secondly, use transfer matrix arithmetic to have finished the relative program to calculate the critical speed of flexible multi-tray rotor bearing system by matlab language . thirdly . finish program the unbalance response using riccati-transfer matrix arithmetic and finity buck arithmetic . fourthly, answer to the high vibration of uncontroled system when cross the critical speed, come out to adopt changing clearance damper bearing to control the viberation
本文对多柔盘转子-支承系统的振动现象做了以下初步探索：用质量离散化方法把原转子系统简化；采用matlab语言编制了对传递矩阵法计算多柔盘转子-支承系统的临界转速；用matlab语言对riccati传递矩阵法和有限元法编制了程序计算系统的不平衡响应；并针对其过临界转速时振动较大的现象，提出采用变间隙控制油膜刚度和阻尼，从而使原系统的在特定转速(临界转速)的一段范围内不平衡响应减小；并从被动控制与主动控制两方面进行数值仿真，取的了较好的控制效果。
