摘　　要：采用有限元软件Ansys和专业疲劳分析软件MSC.fatigue,就大型挖泥机臂架结构进行全寿命疲劳分析,运用Ansys中的MPC多点接触建立梁单元和板单元的混合模型,并导入MSC.fatigue中进行疲劳寿命计算,计算结果表明,臂架结构疲劳寿命满足设计使用年限要求,对该类型工程船舶机械的寿命分析具有指导意义。Total life fatigue analysis is conducted on boom structure of large dredger using finite element software Ansys and professional fatigue analysis software MSC.fatigue.A hybrid model of beam element and plate element is established by using MPC multi-point contact in Ansys and imported into the MSC.fatigue for fatigue life calculation.The calculation results indicate that the fatigue life of boom structure satisfies the requirements on design service life.The research is significant to life analysis of similar engineering ship machinery.
