pulsating motion 中文意思是什麼
pulsating motion
解釋
脈動運動-
By employing cole ' s classical theory of bubble dynamics, the motion of bubble produced by the underwater explosion and the corresponding bubble pulsating pressure are calculated. a profile function of the shock wave and its parameters are determined according to the principle of wave profile similitude and the equality of impulses. finally an analytic formula is derived to simulate the whole time history of the pressure from the front shock wave to the bubble pulsation, representing the fluid loadings of the underwater explosion
木文首先應用庫爾的經典水下爆炸氣泡運動理論計算出氣泡的運動和脈動的壓力波形，再依據波形相似的原則尋找波形模擬函數，用沖量相等的原則確定波形參數，得出了從沖擊波到氣泡脈動壓力整個過程對水下爆炸載荷進行模擬的解析公式。 -
The main disadvantage of pmsms is its pulsating torque. torque smoothness is an essential requirement in a wide range of high - performance motion control applications
然而，無刷直流電動機具有較大的轉矩脈動，而對于這些應用場合，轉矩平滑通常是基本要求。
