【摘要】 对一种手动爬楼梯轮椅的运动过程进行了分析。在各部件不与楼梯台阶相干涉的条件下，计算出了车辆质心位置的座标值，并依此绘出质心的位移轨迹曲线。计算了轮椅在上爬楼梯时运动期的中间段质心的速度、加速度以及人的操纵力值。为进一步进行动力学分析和轮椅的改进设计提供了依据。更多还原

【Abstract】 The article analizes the move procedure of manual stair - climbring wheelchair. Under the non - interferenec condition between the parts andsteps, calculates the coordinate ualue of the position of the vehicle nature centre and therefore draws out its move curve. It also calculates the middle - moving period nature centre’s speed, acceleration and arm force value 0f the wheelchair s climbing and thus provides the basis for the further analysis of dynamics and the design inprovement of the wheelchair.更多还原
