为了减小掘进机电控箱的振动,利用UG建立某新型掘进机实体模型,并导入到ANSYS Workbench中进行模态分析,从而得到掘进机各阶固有频率和振型。结合分析结果,提出合理的设计改进,使整机固有频率尽量远离共振频率范围,避免电气元件损坏。
In order to reduce the vibration of TBM, a new TBM solid model was established by UG and imported into ANSYS Workbench for modal analysis to obtain the natural frequencies and vibration modes of TBM. Combined with the analysis results, reasonable design and improvement are proposed to make the natural frequency of the whole machine keep away from the resonance frequency range as much as possible to avoid the damage of electrical components.
