摘　　要：电磁力互动柱塞泵是一种新型的液压泵,柱塞运动控制不当将和泵体产生冲击振动和噪声。考虑电磁力、液压动力、摩擦力等因素,建立电磁力互动柱塞泵动力过程仿真的数学模型,对电磁力进行仿真与试验研究,发现两者具有较好的一致性。电磁力随着柱塞行程增大单调递增且变化越来越快,最大值接近1000 N;柱塞从下止点运动到上止点且保持通电状态,速度随电磁力变化趋势越来越大,到上止点时产生剧烈冲击和噪声;缩短通电时间,可使柱塞运动到上止点时速度近似为0,避免了冲击且电消耗大幅度降低。Electromagnetic interaction plunger pump is a new type of hydraulic pump.If the plunger motion is not controlled well,shock,vibration and noise occar in the plunger and the pump body.In consideration of electromagnetic force,hydraulic power,friction force and other factors,this article establishes the mathematical model of the dynamic process of the electromagnetic interactive plunger pump.Then the electromagnetic force is simulated and experimentally studied,the simulation and study results is of good consistency.The electromagnetic force increases monotonously with the increase of the plunger stroke,and it changes faster and faster.The maximum value is near 1000 N.When the plunger moves from bottom dead center to top dead center,the coil is still in energized condition,the speed increases with the electromagnetic force.And when the plunger reaches the top dead center,it generates violent Impact and noise.By shortening the energization time,the velocity of the plunger approaches to zero when the plunger is moved to the top dead center,thus avoiding the Impact and greatly reducing the electric consumption.
