摘要
Abstract
In practical production, high speed rotors will produce the non-plane motion due to unbalance torques. In this paper, through numerical simulation and experiment, kinematic characteristics of non-plane ball type automatic balancing devices under the critical speed are studied. Using the ill-conditioned detection method, automatic switching between the stiff method (ωmethod) and the non-stiff method (RK-45 method) in the numerical simulation is realized. The corresponding ill-conditioned differential equations of the ball-type automatic balance device with non-plane motion are solved. The correctness of the mathematical model and numerical simulation results is verified through experiments. It is concluded that the ball-type automatic balance device has a good damping effect for the planar vibration and spatial rotation of the rotors with non-plane motion. The numerical simulation algorithm has reference significance for multi-body problem analysis.关键词
