摘　　要：以旋挖钻机为研究对象,通过分析旋挖钻机发动机的工作特性和液压泵的工作特性,进行发动机与液压泵的自动匹配优化设计。根据控制器读取液压泵当前压力值来确定当前负载的大小,实现发动机转速随着负载变化进行自动补偿,实现发动机功率和转矩的稳定输出;通过PID控制技术自动调节液压泵调压阀电流,实现发动机和液压泵输出功率和输出转矩的最佳匹配,以提高旋挖钻机施工效率和燃油经济性。Taking the rotary drilling rig as the research object,by analyzing the working characteristics of the engine and hydraulic pump of the rotary drilling rig,the optimal design of automatic matching between the engine and the hydraulic pump is carried out.According to the current pressure value of the hydraulic pump read by the controller,the current load is determined,the engine speed is automatically compensated with the load change to achieve stable output of engine power and torque.Through PID control technology,the regulator current of the hydraulic pump is automatically adjusted to achieve the best matching of the output power and output torque between the engine and the hydraulic pump to improve the construction efficiency and fuel economy of the rotary drilling rig.
