轉葉力矩 的英文怎麼說
中文拼音 [zhuǎnyèlìjǔ]
轉葉力矩
英文
spindle torque-
High speed : high efficiency and low resistance moment, under the same conditions, the generator speed can reach at 1. 5 or 3 times of the normal generator ' s, so it can be make good use of
轉的快：電機輕快高效，阻力矩極小，同等條件下，轉速是其它電機轉速的1 . 5到3倍，風葉的風能利用系數更高，可以發更多的電。Finally, the wave equation of the electromagnetic field of this kind damper is derived from the maxwell ' s equation. the magnetic flux density at the boundary is assumed to be harmonic, so the analytical result of the wave equation is solved. when the rotor rotates, eddy currents flowing inside the conducting material field are caused
最後，應用ahrens的電磁軸承簡化模型，從maxwell方程出發推導了應用於本文所述的被動式電磁阻尼器的波動方程，並用傅立葉級數把矩形磁場展開的諧變磁場作為磁場的邊界條件，通過求解波動方程得到磁場的解析解，從而計算了阻尼器對轉子的電磁力和由渦流引起的切向力產生的阻尼器附加功耗。Based on the assumption of periodic rubbing force in rotor system, the rubbing forces onto each node of rotor system are estimated by modal expansion technique and the sub - harmonic decomposition of residual matrix between faulty and faulty - free vibration signals of rotor system through fft ( fast fourier transformation )
基於轉子系統碰摩力的周期性假設，利用模態擴展方法，對故障和健康轉子系統振動信號的殘差矩陣進行傅立葉級數的分頻諧波近似，估算得到轉子軸承各節點的碰摩力。
