动坐标系 meaning in English
body axes system
moving coordinates system
Examples
- Relative coordinate decoupling concept , the counterpart of conventional decoupling , was constructed to depict special conditions which were easy for the relative coordinate
针对某些更便于在动坐标系下描述的情况，引入了相对于传统解耦（即绝对坐标解耦）而言的动坐标解耦的概念。 - Combining with the energy fluxes balance above fuel surface , the simulation and calculation of transient heat conduction of the pe fuel with liquid layer while melting and pyrolyzing are considered by use of the moving coordinates . the calculated regression rate of the pe fuel approximately tallies with the same kind of hybrid rocket motor test data from the abroad
建立了pe燃料的熔化、热解、导热模型，应用动坐标系，结合燃料表面热环境，对具有液体层的pe燃料的熔化、热解和内部瞬态导热过程进行了模拟计算，计算的pe燃料退移速率与国外同类试验的测量结果符合较好。 - Kinematic analysis : by denavit - hartenberg method , space geometry relationship of each pole relative to fixed reference frame can be described with equal index transform , also do space relationship of two adjacent poles with 4x4 equal index . so equivalent equal index transform matrix can be deduced from them . when sportive equations and sportive coordinate frame of workpiece exercise point are set up , the coordinate values of exercise point can be got , the pose and situation of two manipulators are analysed , in the end each joint valiable and its velocity , acceleration are worked o ut
运动学分析：利用denavit ? hartenberg法，用齐次变换描述各个杆件相对于固定参考系的空间几何关系，用一4 4的齐次变换矩阵描述机邻两杆的空间关系，从而推导出等价齐次变换矩阵，建立两机械手运动方程，确定工件作业点随动坐标系，求出作业点坐标，对两机械手的位姿进行解析，求出两机械手的各关节变量及其速度、加速度值。
