摘　　要：新型四连杆变幅机构的特点:后摇杆驱动、臂架活动范围大、外观和几何形态特别、重心高度低。运用该变幅机构的浮式起重机已在欧洲的荷兰等国的港口中投入使用,完成转载、过驳等装卸作业,实现带载变幅,即工作性变幅。运用机构学、力学原理来分析该新型四连杆变幅机构的受力情况,经实例分析计算并使用MATLAB编程实现,证明了该新型四连杆变幅机构的力学性能良好,非常适宜带载变幅作业。The double-link luffing mechanism is in general use for portal slewing cranes and floating cranes.But,a new double-link luffing mechanism come to light.There are great differences in outward appearance,geometric shape,luffing performance between jib type crane with back-driving and normal double-link type crane.The crane can handle both ship-to-ship and ship-to-shore operations swiftly and efficiently in the Netherlands.Based on theory of mechanism and principle of force,force characteristic of luffing mechanism of jib type crane with back-rocker driving is studied.By sample analysis,a new double-link luffing mechanism has good characteristic of force.
