前言在动平衡机中,前置滤波器性能如何,是影响整机性能的关键之一。近几年来,人们已开始将数字自动跟踪滤波器用于动平衡机测量线路的前置滤波。它的主要特点是工作频带宽,幅频特性和相频特性平坦,Q值可以制做到很高,工作稳定,特别是在低转速的情况下,如果选用其它类型的滤波器,将会是体积大,稳定性差,难以制做。我们在转速为150r/min-1200r/min的QDP-1000型曲轴动平衡机中和转速在3000r/min
Preface In the balancing machine, the performance of the prefilter is one of the keys to the performance of the whole machine. In recent years, digital auto-tracking filters have been used to pre-filter lines of dynamic balancing machines. Its main features are wide working frequency band, flat frequency characteristics and phase frequency characteristics, Q value can be made to a high, stable work, especially in the case of low speed, if you use other types of filters, will be Large size, poor stability, difficult to make. We in the speed of 150r / min-1200r / min QDP-1000 crankshaft balancing machines and speed at 3000r / min
