摘要:
采用Ansys 软件对地铁高频辅助变流器柜体进行模态分析,可知辅助变流器柜体第一阶振动频率对应的振型为盖板法向振动。为增强盖板的刚度,以提高盖板第一阶振动频率为目标,在OptiStruct 软件中对其进行形貌优化。同时,为减轻吊耳重量,对吊耳进行了拓扑优化。优化结果表明:辅助变流器柜体的第一阶振动频率提高32.0%,吊耳减重21.0%,优化效果较为明显。
Abstract:
Modal analysis of the high-frequency auxiliary converter for the metro was conducted with Ansys software, and according to the results, the cover vibration was most in the normal direction under the first-order vibration frequency of the auxiliary converter. In order to improve the stiffness of the cover, the enhancement of the first-order vibration frequency of the cover was taken as the target, and topography optimization of the auxiliary converter cover was carried out with the OptiStruct software. Besides, the topology optimization of the lug was also conducted to lighten the lug. With the results of the optimization, it was shown that the firstorder vibration frequency of the auxiliary converter was improved by 32%, and the weight of the lug was decreased by 21%, with an obvious optimization effect.
