明白您的要求，下面将为您生成刚性转子动平衡的目的的英语翻译：

The purpose of rotor dynamic balance is to ensure 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.
