基于力传感器的刚性转子动平衡实验方法.

In order to solve the dynamic balancing problem of rigid rotor, a comprehensive experimental balancing method based on tension and pressure sensor was proposed. Firstly, based on the principle of dynamic balance, the experimental equivalent model of rotor unbalance was constructed, and the theoretical unbalance was solved to ensure the rigor and rationality of the experiment. Then, the structural design, instrument and equipment were selected, the rotor dynamic balance experiment platform was built to ensure the stability and repeatability of test data. Finally, the platform was used to collect mechanical performance data, the amplitude and phase of shafting unbalance were analyzed, and the rotor dynamic balancing experiment was carried out by adding balance mass, and the feasibility and effectiveness of the comprehensive experimental balance method based on tension and pressure sensor were verified. The experimental results show that the unbalance mass amplitudes of the left and right ends are respectively 2. 2 kg and - 3. 8 kg, and the unbalance mass amplitudes of the left and right ends are respectively 1. 2 kg and - 1. 4 kg; the unbalance of the rotor system is reduced by 1. 4 kg, and the balance rate is 87. 5%, which verifies the feasibility of the balancing method based on the cooperation of tension pressure sensor and encoder to eliminate unbalance. This experimental platform lies in the use of tension pressure sensor and encoder to accurately measure unbalance mass and phase, provides a new idea for solving the dynamic balance problem of rotating machinery, and is helpful to improve the operation efficiency and prolong the service life of rotating machinery.
