摘　　要：水下绳锯机是一种快速发展的清洁环保切割工具,在水下油气管道出现问题时,可以采用其切割维修。水下切割的成本很高,要求绳锯机在工作中不更换绳锯的前提下高效完成切割,这就要求对管道切割过程中的参数进行优化。文中通过三因素三水平两指标的正交实验方法,得出了绳锯机切割过程中,不同截面位置处的切割速度、进给速度和串珠绳张紧力的最佳组合值。水下切割实验表明,该结果达到了预期目标,从而为绳锯机的水下切割最佳控制提供了一定的基础。Underwater wire saw is a rapid development clean and green cutting tool,when there is a problem of underwater oil and gas pipelines,it can be used to finish cutting service. Underwater cutting is very expensive,which requests efficient completion of cutting in operation on premise that wire saw is not replaced,all those require the pipe cutting parameters to be optimized. The best combination of the cutting speed,the feed rate and the beaded rope tensioning force at the different sections position was obtained in the wire saw cutting process by three factors and three levels of two indicators orthogonal experiment. Underwater cutting experiments show the results achieve the expected goals,which provide a certain foundation for the optimal control of wire saw underwater cutting.
