摘　　要：为提高150 MN水压机锻造精度,必须提高活动横梁的运行控制精度。由于工作过程中因立柱变形、工作缸内水的弹性变形、活动横梁惯性压下、锻件可塑量不同、活动横梁质量大等因素造成锻造精度很难达到高精度。通过设计活动横梁位置自适应预控工艺方法,有效解决锻造精度控制问题。The improvement of forging precision of 150MN water-hydraulic press requires the improvement of control precision of the slide movement.It is difficult to reach high forging precision because during the operation of the press,the columns distort,elastic deformation of water in the working cylinders,inertial down-movement of the slide,different plasticity of forged pieces and large mass of the slide.The self-adaptive pre-control technique for control of the slide position can solve the problem about the control of forging precision effectively.
