The working principle of hydraulic jumping control system was introduced and taking the Is wrapper roll of certain hot-coiler as investigation object, the load test scheme of physical simulation was set up to carry on theoretical kinetic analysis and mathematical modeling for the system. By means of simulative load test, the performance of valve-controlled asymmetric cylinder system was investigated and the steady-state and dynamic response manifested in the position and pressure links were analyzed to verify the rationality of system component selection and adjust the processing parameters such as the plate-feeding speed so that the jumping action of the system was ensured in an orderly way and the operation efficiency and stability of the coiler were improved.%介绍液压踏步控制系统工作原理,以某型号卷取机1 #助卷辊为对象,确立物理模拟负载试验方案,对系统进行理论受力分析和数学建模.通过模拟负载试验研究该阀控非对称缸系统的特性,对系统在位置环和压力环中所表现出的稳态特性和动态响应情况进行分析,验证系统元器件选型的合理性,调整诸如进板速度等工艺参数,保证系统有条不紊进行踏步动作,提高卷取机工作效率和稳定性.
