摘　　要：本文提出换杆法。通过机架和摇杆位置互换 ,产生一新的曲柄摇杆机构的方法 ,将已知机构的行程速度变化系数为K ,摇杆的摆角 ψ,机架长度为L4,未知摇杆长度L3 的曲柄摇杆机构设计难题 ,转化为一常规的已知K、ψ、L3In theis paper, the method of changing the bar of the Crank and rocker structure is introduced, Bymeans of exchanging the positions of the frame and the rockes, the problem of designing its structure with known factors K (Travel speed variation coefficient),ψ(the Crank's swining angle) and L4 (The length of the frame);and the unknown facfor L3 (The length of the rocker) can be transformed into a conventional problem of designing with K,ψ,L3 known.
