摘　　要：考虑动臂缸和转斗缸的工作行程对装载机工作性能的影响,将两个缸的工作行程连同反转六杆机构铰接点位置坐标作为设计变量,在满足装载机的性能指标和约束条件下,以提高动臂缸的传力比为优化目标,借助ADAMS/View软件,建立了ZL50型装载机的反转六杆机构的参数化模型,进行了优化设计。设计结果明显改善了装载机的平移性能和卸载距离,大幅提高了动臂缸的传力比,达到了优化设计的要求。In consideration of the effect of the work stroke of lifting cylinder and bucket cylinder on the working performance of loader,the work strokes of the two cylinders are then selected to be design variables together with the position coordinates of the pivot points of the reverse-six-link mechanism,at the same time,the optimization objective is set to improve the ratio of transferring force of lifting cylinder under the condition of meeting the performance indexes and other constraints.With the help of ADAMS/View software,a parameterized model of reverse-six-link mechanism of type ZL50 loader is built,and optimization design is carried out.The design result shows that the translation performance and the unload distance,as well as the ratio of transferring force of lifting cylinder are greatly improved,those requirements of the optimal design are achieved.
