| 摘 要： | 加减速控制方法是现代高精度、高性能数控系统中的重要环节,现代加减速控制方法主要分为梯形速度曲线与S形速度曲线。通过对梯形速度曲线与S形速度曲线的比较,可知S形速度曲线在减小冲击和振动方面更具有优势。接着对S形速度曲线进行了深入研究,给出了加速度、速度和位移各个时间段的计算公式。由于在实际插补计算时,会有各种特殊情况出现,所以又对各个特殊情况进行了讨论,得出各个特殊情况的计算公式。最后给出了程序段预处理过程流程图和程序段插补过程流程图。

| Abstract: | Acceleration and deceleration control method is an important part of modern high-precision and high-performance CNC system. Modern ways of controlling acceleration and deceleration can be divided into the trapezoidal speed curve and the S-shaped speed curve. By comparing the trapezoidal speed curve and the S-shaped speed curve,we can find S-shaped speed curve has a great advantage in reducing the rate of impulsion and vibration. Then,have an in-depth study on S-shaped curve,and find out the acceleration,vel... |
