摘　　要：为抑制数控系统直线加减速运动中加速度突变引起的柔性冲击,以单轴工作台为实验研究对象,设计负脉冲零振动(NZV)、负脉冲零振动和微分(NZVD)和负脉冲极不灵敏(NEI)整形器,将其优化工作台直线加减速运动,研究优化前后工作台运动时柔性冲击的变化。实验结果表明采用合适的负输入整形优化数控系统的直线加减速运动,可以抑制加速度突变引起的柔性冲击,实现运动平稳。In order to curb the flexible impact caused by acceleration mutations in linear acceleration and deceleration motion of CNC system, single-axis Workbench was used to experimental research. The Negative Zero Vibration （NZV）, Negative Zero Vibration and Derivative （NZVD） and Negative Extra Insensitivity （N EI） shapers were designed to optimize linear acceleration and deceleration movement. Study the flexible impact changes before and after optimization. Experimental results show that appropriate negative input shaping could optimize linear acceleration and deceleration movement of CNC, so that suppressed the flexible shock caused by mutations and achieved smooth movement.
