滤波器是增强动平衡试验机的抗扰能力,提高精度和生产效率等所必不可少的核心部件之一。因此在高精度动平衡中,研究和制造高质量的前置滤波器,是摆在我们面前必须解决的课题。我们知道,机械振动是一个很复杂的运动。动平衡试验机在运转时,其传感器输出来的信号,除了基波信号外,另外还有其他谐波分量,尤其是在低速平衡大转子时,随机性的振 Filter is to enhance the anti-interference ability of dynamic balancing test machine, improve precision and production efficiency, one of the essential core components. Therefore, in high-precision balancing, research and manufacture of high-quality pre-filter, is placed in front of us must solve the problem. We know that mechanical vibration is a very complex movement. Dynamic balance test machine in operation, the sensor output signal, in addition to the fundamental signal, there are other harmonic components, especially in the low-speed balance of the large rotor, the random vibration
