Numerical model for influence of unbanaced magnetic pull on the critical speed of motor-driven spindle

摘要

Spindles, key components of a spinning frame, are also the symbol of textile industry. Its dynamic performance directly affects the quality and yield of yarn . At present, the spindle, up to 25000 rpm, belongs to high speed of rotors. In the process of work, it has to face the vibration problem, which is the main reason that spindle cannot speed up and broken yarn.
