摘　　要：针对传统的直线加减速和指数加减速算法在进给过程中存在柔性冲击的问题 ,提出了一种适用于高速进给的新型柔性加减速算法 ,采用三角函数构造加减速曲线 .对这种加减速模式进行了详细的分析和探讨 ,并提供了一种新型数控进给系统设计方法 .The traditional acceleration/deceleration algorithms such as the linear and the exponential are not suitable for high speed motion because there would be impacts existing in motion. A new flexible acceleration/deceleration algorithm suitable for high speed motion system was introduced, in which the trigonometric function is used to construct the acceleration/deceleration functions. In this algorithm, the velocity, acceleration, jerk and displacement are all consecutive so that the system is more flexible and the flexible impacts are completely avoided. This algorithm was analyzed and discussed in detail, supplying a new method for the design of NC motion system.
