In this paper,a dynamic model for 3-RRRT parallel manipulators is set up based on the d Alembert principle and the force reduction method.

基于達朗伯原理和等效力方法建立了3-RRRT型并聯機器人的動力學模型,得出其正向動力學與反向動力學方程,并給出反向動力學的MATLAB數值仿真。

Layout design method based on D Alembert principle is proposed in this paper,trying to solve the system vibration problem caused by moving-mass,as well as system coupling problem caused by principal axis misalignment.

針對滑塊運動容易引起系統抖動,以及慣性主軸偏移引起系統耦合嚴重等問題,基于達朗伯原理對變質心飛行器結構布局進行了設計。

The certain solution to the free transverse vibration caused by an initial condition in a symmetrical,soft and light string with infinite length is worked out,thus a more satisfactory physics interpretation of the Alembert formula is presented.

從最基本的物理現象入手,考慮到真實的物理過程,從另一個角度來探求一根無限長的均質柔軟輕弦在初始條件作用下所引起的自由橫向振動在弦中傳播的定解問題的解,從而對達朗伯公式作出一個比較圓滿的物理解釋。
