This technology applies "damping particles" to a rotating mechanism. By filling a proper amount of particles into the internal cavities or the additional cavities of mechanisms, the unbalanced inertia force can effectively be reduced, and the vibration and noise during rotating can also be attenuated properly. This technology enhances the traditional dynamic balancing method for rotor systems and provides a much better strategy to reduce vibration and noise. This innovative technology will improve operation performance and durability for the rotor systems, and will be extensively used in the near future.This innovative technology breaks through the limitation of the traditional dynamic balancing method, which cannot reduce rotor vibration effectively. By using two way coupled MBD-DEM modeling and analysis, the dynamic behavior of rotor systems can be reasonably predicted and the optimal design for the amount of particles can be achieved. This technology not only corrects the unbalanced centrifugal forces of the rotor systems, but also attains the purpose of suppressing vibration.This technology can be applied to any rotor systems that require dynamic balance correction, and also has a function of vibration suppression. Holes or a device with receiving cavities can be directly embeded on the rotor systems. A proper amount of particles are filled into the internal cavities or the additional cavities of mechanisms, and cover plates are then finally sealed. This technology can be easily implemented by today＇s processing and manufacturing methods, and has the advantages of low processing cost, good flexibility in geometric design, little change to the original structure, high temperature resistance and wear resistance.
