摘要
从共振条件、共振位相、共振能量三个方面详细论证了位移共振与速度共振的区别 ,得出如下结论 :发生位移共振时 ,强迫力圆频率 P 应满足 P =ω20 - 2 β2 ,速度与强迫力并不同位相 ,总机械能随时间而变化 ,发生速度共振时 ,强迫力圆频率P应满足P =ω0 ,速度与强迫力同位相 ,总机械能保持不变。
This essay demonstrates in detail the distinctions of displacement resonance and speed resonance from condition,position,energy of resonance and draws the following conclusion:when the displacement resonance works,the circularity frequency of the force should satisfy the condition P=ω 2 0-2β 2,and the speed and the force don't have the same resonance.As a result,the total mechanical energies vary with the time;when the speed resonance works,the circularity frequency of the force should satisfy the condition P=ω 0,and the speed and the force share the resonance,the total mechanical energies remain the same.
