摘　　要：连铸中间罐车液压马达行走驱动控制原理通常采用伺服阀或者比例阀进行控制,该文介绍了中间罐车的具体结构及液压马达的行走驱动控制要求,提出了采用普通换向阀进行组合控制的方式,并对该原理进行了仿真研究。通过现场的使用,证明该控制原理具有运行稳定、结构简单、故障率低以及维修容易等优点。Travelling control system of hydraulic motor in tundish car is usually controlled by servo valve or proportional valve, this paper introduces the specific structure of machinery and travelling control requirementsof hydraulic motor, proposes the combination of normal directiona lvalve into travelling system as well asconducts simulated analysis to this model.The controlling system has been proved on-site thatit has stable operation, simple structure, low failure rate and easy in maintenance.
