摘要
对某型动车组车下主电动机风道和主变压器风道进行了模态分析,从设计结构方面避免动车组车下风道与车体共振而导致风道出现裂纹。
The modal analysis is made for the air ducts of the main electric motor and the main transformer under a certain type of multiple units. The resonance between the air ducts under the multiple units and the carbody is avoided from the aspect of designed structure to prevent cracking in air ducts.
