Abstract
The balance goal of the existing offline dynamic balance detection method is to minimize the amplitude of each vibration measurement point. After balancing, many high-speed rotors need to be equipped with an online dynamic balance system to maintain the rotor at a higher speed and run smoothly. This shows the existing offline dynamic that has much room for improvement in balance. A detection method that can measure the eccentric mass at each position of the rotor axis is proposed. Now the goal is to fit the curve of the center of inertia closer to the geometric center, hoping to minimize the eccentric mass on the rotor.
