6. 计算结果分析
原动件AB为曲柄,转动范围0~360°,本程序设AB杆与x轴正向夹角为0时为起始位置,以10rad/s的角速度逆时针旋转。本程序分析以原动件旋转1/2°为计算步长。
当原动件转至ψ1=5.7°左右时,F运动至最左端,坐标为(463.3mm,65mm) 至ψ1=200°左右时,F运动至最右端,坐标为(826.5mm,65mm)
由点F的位移图、速度图、加速度图可知,滑块先是向左运动,做加速度减小的减速运动,运动至F点坐标处(463.3mm,65mm)后返向(此时ψ1=5.7°),向右做加速度一直减小的先加速后减速运动直至速度为零,再向左做加速度一直增大的加速运动至最右端F坐标(826.5mm,65mm)(此时ψ1=200°),最后向左做加速度减小的减速运动,完成一个周期的运动。
