铁液包倾转力矩是铁液包结构设计中一个重要问题。
The torque of the molten iron ladle is a very important problem when designing the structure of molten iron ladle.
本文采用有限元法建立了铁液包倾转力矩数学模型。
The mathematical model of the molten iron ladle was established using finite element method.
结果表明，随着预紧力和真空度的增加，马达的堵转力矩增加而空载转速下降；
The results show that stalling torque increases and no load speed decreases with the increase of the pre-load and degree of vacuum.
