由全程分析法研究质点沿转动杆的运动

Motion Study of a Particle on a Rotation Bar Using Full-process Analysis Method

分析了质点沿着定轴转动的直杆和直角杆作相对直线运动,比较了点的合成运动法和全程分析法。结果表明:全程分析法能够得到每一时刻点的轨迹方程、速度和加速度,从全局角度把握点的运动规律,比应用点的合成运动分析更简便。由全程分析法分析了的该质点的运动规律,得到了其运动的轨迹、弧长,速度和加速度等的规律。

The quantities of motion including the displacement equation,velocity and acceleration of a point at any time can be analyzed by using the full-process analysis method which is easier than the composition nmtion sometimes.The motion of a particle relative moves linearly on the straight bar and rectangular bar,which are rotation about an axis.The path of motion,length of arc,velocity and acceleration are all obtained.
