Effect of change of mean angular velocity of the crank on stability of SCWC was analyzed. 其后，分析了爬楼梯轮椅曲柄平均角速度的改变对其稳定性的影响。
The result shows that during a fast flexion the short time average angular speed is nearly constant, but the instantaneous speed appears to be a fluctuation wave. 模拟结果表明，在快速屈曲过程中，食指短时平均角速度近似为匀速，瞬时角速度呈现阻尼振荡形式。
