大多数确定滑块——曲柄机构瞬时线速度和瞬时加速度的运动方程解起来是冗长而费时的。这里是由平面三角学原理和速度矢量多边形图解法推出的简化方程。该方程只有一个变量(曲柄角:θA),与由更严密的数学分析方法推导出的关系式相较比,解这个方程更快。在典型的滑块——曲柄机构中,曲柄AB以角速度ω绕铰链A旋转。角θA是曲柄 Most of the equations that determine the instantaneous linear velocity and instantaneous acceleration of a slider-crank mechanism are lengthy and time-consuming. Here is a simplified equation derived from the principles of plane trigonometry and velocity vector polygons. This equation has only one variable (crank angle: θ A), which is faster than solving the relation derived by the more rigorous mathematical analysis. In a typical slider-crank mechanism, crank AB rotates about hinge A at angular velocity ω. Angle θA is a crank
