摘要
本文采用有限元法对核电站用三相电机在地震载荷、自重、扭矩和单边磁拉力等多种载荷组合作用下进行了抗震性能计算分析,结果表明在上述载荷作用下,电机机体的应力状况满足抗震要求,电机轴的变形在允许限值内。
In this paper, the seismic performance analysis of the three-phase motor used in nuclear power generating station is carried out under the combined loads, including earthquake loads, dead weight, torque and unilateral magnetic force by using the finite element method. The results show that the stress of motor meets the seismic requirements for equipment and the motor shaft deformation is within the allowable limits.
