When the rotor is in uniform motion, countless particles inside the body will generate inertial forces, forming an inertial force system. To determine whether this rotor is a balanced rotor, it must be determined based on the synthesis of its inertial force system.

Whether the rotor needs to be statically balanced or dynamically balanced depends on the specific situation. It depends on the weight, shape, speed, support conditions, and purpose of the rotor.

The vibration of the rotor, machine base, and foundation system is influenced by many factors, such as the vibration quality of the foundation of the machine base, the rigidity of the bearings and foundation, the proximity of the working speed to various resonance frequencies, and so on. The relationship between vibration amplitude and residual unbalance of the rotor is not simple, and sometimes experimental methods can be used to determine many unbalance quantities of the rotor.

At the same time, it is necessary to understand the performance indicators, specifications, and characteristics of various balancing machines produced by balancing machine manufacturers, which is the basis for selecting balancing machines. According to the standard naming convention for balancing machines, the "workpiece quality" is the main parameter of the balancing machine. The 'workpiece quality' only refers to the bearing capacity of the balancing machine's supporting swing frame. When selecting a balancing machine, it is necessary to ensure that the quality of the verified workpiece does not exceed the range specified by the balancing machine. Although the balancing machine has been designed with safety considerations in mind, for safety reasons, it should not be overloaded during use. If the workpiece for balance verification is not only one type, it should be ensured that the quality of all workpieces within the range of use does not exceed the values specified by the balance machine.

Nowadays, people's requirements for work environment safety are constantly increasing, which has an impact on multi rotating machinery, and balancing machines are no exception. In order to correctly select a rotor balancing machine, it is necessary to have a thorough analysis and understanding of the structure, purpose, balancing accuracy, working speed, support conditions, transmission mode, and other aspects of the rotating workpiece.

In order to reduce the vibration of rotating machinery, increase the working speed, extend the service life of workpieces, reduce the imbalance of rotating workpieces, and achieve this goal, a suitable balancing machine is usually selected to perform balance verification on rotating workpieces.

Due to the significant differences in the variety, shape, weight, and support form of rotating workpieces that require balance verification, as well as the varying requirements for balance accuracy, it is necessary to select a suitable balancing machine based on the characteristics of the rotor when performing balance verification on rotating workpieces. If the selection is improper, it often leads to the failure to achieve the expected balance accuracy, resulting in low work efficiency and even inability to balance.
