摘　　要：串联导杆机构的已知特征是它的尺寸设计相对容易、输出位移的设计范围大以及传动角比较大。基于数学分析，串联导杆机构的传动特征得到了拓宽，当满足一组几何条件时，得到了导杆在单极限或双极限位置作直到三阶停歇的串联导杆机构；当满足另一组几何条件时，得到了摆杆作近似等速比传动的串联导杆机构。通过VB编程、参数化与可视化的方法，展示了这2类机构的动画、输出位移及其1—3阶导数的曲线与数值表，表明了虚拟实验在因素完全可控对象的客观规律的寻找与再现上的优越性。Known properties of series guide- bar mechanisms are that its dimension design is relatively easy; design scope of its output displacement is relatively large and transmission angle is larger. Transmission properties of series guide- bar mechanisms are broaden by mathematical analysis. A type of series guide- bar mechanisms which guide- bar does unto three- ordered intermittence at one or two limit position （s） is got ten when a group of geometric conditions are satisfied. Another type of series guide- bar mechanisms which rocker does approximately equal velocity ratio transmission is got ten when another group of geometric conditions are satisfied. Animation, curve and numerical number of output displacement and one to three order differential on two types of mechanisms are shown by VB program; parametric and visual methods. It is demonstrated that virtual experiment possesses superiority in searching and reproducing objective law of the object controlled by factors which can be completely controlled.
