柔性转子的动平衡是高速、大型回转机械设计、制造中的重要技术问题之一。六十年代以来,随着回转机械容量的不断加大,由于受离心力的限制,转子长度显著增加,弯曲刚度变小,其运转时的弹性变形已经不再能忽视,于是,柔性转子的动平衡技术和理论在原有的刚性转子动平衡基础上得到了发展。起初,振型平衡法占主导地位,以后随着电子计算机的发展和普 Dynamic balancing of flexible rotor is one of the important technical problems in the design and manufacture of high-speed and large-scale rotary machinery. Since the 1960s, with the continuous increase of rotating machinery capacity, due to the centrifugal force limitation, the rotor length increases significantly and the bending rigidity becomes smaller. The elastic deformation of the rotor can no longer be neglected. Therefore, the dynamic balance of the flexible rotor The technology and theory have been developed on the basis of the original rigid rotor dynamic balance. At first, the vibration mode balance method dominates, with the development of computers and computers
