摘　　要：当前全地面起重机在执行主臂变幅或者主臂伸缩时,可能会产生安全性问题,影响操作的连贯性,并且作业效率相对不高。针对这类问题,结合起重机基本模型,提出一种卷扬随动的控制策略,优化起重机的操控方式。在阐述卷扬随动原理的同时,本文以一套起重机仿真实验装置作为平台,说明该策略的具体效果。实验结果表明卷扬随动策略可以有效保障主臂变幅或者伸缩过程中的操作安全,同时进一步提高起重机的作业效率,具有一定的工程实用价值。During the. luffing angle or stretching length of boom in all-terrain crane, it probably causes security issues that affect coherence and has relatively low operating efficiency. For such problems, a kind of hoist servomechanism control strategy based on a basic crane model is proposed. After the explanations of such strategy, the paper also shows the specific effects based on a crane simulation experimental platform. The result of the experiment shows that the strategy can effectively guarantee the security during the operation and further improve working efficiency, so it truly has certain practical engineering value.
