The purpose of rotor dynamic balance refers to the goal of ensuring that the centrifugal force and moment generated by the mass distribution on a rotating rotor are balanced, thereby preventing vibrations and imbalance forces from causing undesired effects on the machine's operation. This is particularly important in industrial applications where rotors can experience high-speed rotation and may encounter conditions that could lead to imbalances or other mechanical issues.

In essence, the objective of rotor dynamic平衡 is to maintain operational stability and reliability for machinery components, ultimately leading to improved performance and extended lifespans for these critical pieces of equipment.
