3 空间R3 中的刚性运动(Rigid Motion in R3) 回想一下第一节,刚性运动是保持点之间的距离和向量之间的角度的运动。我们通过使用刚体变换来描述刚体坐标系相对于惯性坐标系的瞬时位置和方向,从而表示刚性运动。这种表示依赖于这样一个事实,即刚体变换将右手系的正交坐标系映射到右手系的正交坐标系,从而保持距离和角度...
力旋量和互易旋量(Wrenches and Reciprocal Screws) 在这一节中,我们考虑作用在刚体上的力(forces)和力矩(moments),并以此来介绍旋量系统和互易旋量的概念。 5.1 力旋量(Wrenches) 作用在刚体上的广义力由作用在一点上的线性分量(纯力pure force)和角分量(纯力矩pure moment)组成。我们可以把这个广义力表示为R6中...
内容提示: Chapter 7Rigid Body MotionThe motion of extended objects requires a new set of tools and some new methodsas well. We begin with the introduction of the moment of inertia tensor and developthe relations combining it with the angular velocity of a rigid body and its kineticenergy or...
Rigid-Body Motion(旋转变换\Screw motion\Spatial velocities\Force) SE(3)=T=[Rp01]SE(3)=T=[Rp01]SE(3)是一个4X4的矩阵.它具有的性质如下:两个SE(3)的乘积仍是一个SE(3) SE(3)的逆: $$T{-1}=\begin{bmatrix}RT&-R^Tp\0&1\end{bmatrix}$$ T=(R,p)∈R3,x,y∈R3T=(R,p)∈R3...
The center of mass of a rigid body is defined. The concept of the moment of inertia is introduced and shown to be intimately related to angular momentum. The equations of motion (translational and rotational) of a rigid body are written. Conservation of angular momentum of a rigid body is ...
