The horizontal decanter centrifuge is a dual rotor system with small rotating speed difference, of which unbalanced vibration is a "beat" signal.
卧螺离心机是一种具有微小速差的双转子系统，它的不平衡振动信号是一个拍振。
There is inevitable unbalance in the dual-rotor system of the aero-engine, the beat vibration will occur to engine when two rotors are operating at approximately the same speed.
在双转子航空发动机中，由于转子系统不可避免地存在不平衡量，当两个转子的转速比较接近时，发动机会出现拍振现象，拍振将引起振动强度过大问题。
