1) beat
[英][bi:t] [美][bit]
拍振
1.
Under the periodical loads, the shaft must have the torsional vibration, named "beat", because the shafting has not only inertia but also elasticity.
轴系装置由于不仅具有惯性而且具有弹性,因此在周期性荷载作用下,会产生扭转振动,甚至于产生拍振。
2) beat vibration
拍振
1.
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。
2.
Consequently, the vibration was investigated and found to be beat vibration.
技术人员对抗燃油泵进行了振动测试和分析 ,得出此振动属于拍振的结论。
3) rattling
[英]['rætlɪŋ] [美]['rætlɪŋ]
拍击振动
1.
The concepts of high speed impact and low speed contact in gear rattling were proposed firstly in accordance with the disadvantages of the present methods.
针对以往研究齿轮系统拍击振动方法存在的不足,提出了齿轮系统拍击振动中高速碰撞和低速接触的概念。
2.
Considering the torque fluctuation of the driving shaft and the existence of the backlashes in both gear pair and clutch, a lumped mass gear-rattling model is established.
在考虑主动轴驱动转矩波动、齿轮副齿侧间隙及离合器间隙的情况下 ,建立了同时含有离合器间隙和齿侧间隙的齿轮传动系统 (简称双间隙系统 )拍击振动分析的集中质量模型。
4) lateral resonance
横向拍振
5) polarization beat length
偏振拍长
6) metre oscillation
节拍振荡

怪得春光不来久，胡中风土无花柳。天翻地覆谁得知，
如今正南看北斗。姓名音信两不通，终日经年常闭口。
是非取与在指撝，言语传情不如手。
