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.
针对滑块运动容易引起系统抖动,以及惯性主轴偏移引起系统耦合严重等问题,基于达朗伯原理对变质心飞行器结构布局进行了设计。
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.
从最基本的物理现象入手,考虑到真实的物理过程,从另一个角度来探求一根无限长的均质柔软轻弦在初始条件作用下所引起的自由横向振动在弦中传播的定解问题的解,从而对达朗伯公式作出一个比较圆满的物理解释。
