pendulum mass 中文意思是什麼
pendulum mass
解釋
擺體-
The mass of the pendulum bob does not change from one location to another on the earth's surface.
擺錘的質量在地面各處都一樣。 -
A set of non - linear differential equation of this model is formulated based on lagrange ’ s equation. the tension of the cable, the control force of translation and the control torque of rotation are obtained by the method of newton ’ s laws in vector space. the tethered mass system is modeled as a spherical pendulum
本文基於一種常見的繩系單體系統，運用lagrange方程建立了該系統的非線性運動微分方程，採用矢量法對該運動微分方程進行了校核，並推導出吊索的張力、變幅控制力和回轉控制力。 -
In fig 8-8, the pendulum, consisting perhaps of a large wooden block of mass m', hangs vertically by two cords.
在圖88中，沖擊擺是由兩條線豎直懸掛著質量為M』的大木塊所構成。 -
A bullet of mass m, traveling with a velocity v, strikes the pendulum and remains embedded in it.
質量為m的子彈，以速度v飛行，擊中擺錘並嵌入其中。 -
The frequencies of translational actuation influence the stability of the tethered mass system. when the frequencies approach the natural frequency of the system, the period of energy exchange decreases and the amplitude of the pendulum increase. when the frequencies equal to the natural frequency of the system, resonance appears
變幅激勵的頻率對系統穩定性有較大影響，當變幅激勵頻率接近系統固有頻率時，系統面內外能量交換周期減小，擺幅增大;當變幅激勵頻率等於系統固有頻率時，系統面內外均出現共振現象。 -
By keeping this center of mass closer to the rotor disc the pendulum effect is reduced and the helicopter is markedly more stable
保持這種質心接近轉子盤鐘擺效應明顯降低，直升機更穩定 -
In fig 8 - 8, the pendulum, consisting perhaps of a large wooden block of mass m ', hangs vertically by two cords
在圖8 ? 8中，沖擊擺是由兩條線豎直懸掛著質量為m 』的大木塊所構成。
