摘　　要：根据对冷铣刨机消耗功率和发动机输出功率影响因素的理论分析,选择了机器的作业速度作为功率自适应控制参数.在此基础上建立了系统的仿真模型,对使用自适应控制系统前后铣刨机发动机功率的使用情况及其作业效率进行了模拟分析和验证.结果表明:选择以机器作业速度作为功率自适应控制参数是合理有效的;该功率自适应系统能够将机器自动调节在发动机额定功率附近工作,使机器在给定条件下的额定功率利用率和作业效率分别提高了10.2%和6.32%以上.该研究为合理利用发动机功率和提高机器作业效率提供了参考.The influence factors in the power consumption of the cold milling machine and the load feature of the engine are firstly analyzed in this paper. And the machine work speed is selected as the power adaptive parameter. Based on these analyses, a simulation model of the cold milling machine is designed with the software. Whether the engine power utilization of the cold milling machine is reasonable or not is verified through simulation which uses the adaptive power control system. The results show that using the work velocity of the cold milling machine as the control parameter is reasonable and effective. The engine of the milling machine can be set to work at its rated power by the self-adjustment of adaptive power control system. In this case, the rated power utilization ratio of the engine is improved more than 10.2% and the machine efficiency is raised at least 6.32% in various work conditions. The theoretical basis and novel practical methodology can he provided for making good use of the engine power and increasing the machine work efficiency.
