Description

technical field [0001] The invention belongs to the field of automatic dynamic balancing of rotating machines, and relates to an online active dynamic balance measurement and control device and a measurement and control method, in particular to a reconfigurable online automatic rotor balance measurement and control device and measurement and control method based on functional modularization. Background technique [0002] The unbalanced vibration of rotating machinery has always been one of the main reasons affecting the running quality of the machine. Because there are many factors that induce rotor imbalance, such as the design and processing defects of the rotor itself, the assembly and installation accuracy of the rotor, and the wear and deformation of the rotor during the working process, these factors will make the mass imbalance of the rotating machinery inevitable. Online automatic balancing is a new technical means to reduce unbalance. In order to realize online auto...

Its main feature is the use of F240 chip design. Although the measurement and control system composed of it has certain monitoring and control functions, it cannot perform floating-point operations on data and the chip operation speed is low. Therefore, in high-speed grinding machines with high real-time, There are certain deficiencies in the high-precision requirements, and the online real-time measurement and control function cannot be realized

Chinese patent application "A Reconfigurable Monitoring System and Method for Machine Tool Functional Components" (CN102073304A, application date: 2011.01.17) is a reconfigurable machine tool functional component based on the hardware architecture of "embedded monitoring unit + sensor signal conditioning module" Monitoring hardware device, which can realize on-line monitoring of the rotation state of the machine tool, and has high monitoring accuracy, but because there is no corresponding control signal output function, it cannot realize the automatic control of the dynamic balance of the rotating machine

Similarly, in many domestic researches, some systems can realize the monitoring function or control function of the dynamic balance state but cannot integrate monitoring and control in one device, which brings certain difficulties to the measurement and control of dynamic balance, so it is necessary to design A measurement and control scheme that can not only realize the real-time monitoring of the operating state of the rotating machinery but also realize the active control of the unbalance
