摘　　要：对某型号矫直机的万向联轴器进行静力力学和模态分析,应用ANSYS软件建立了万向轴有限元分析计算模型,分析计算了万向轴及十字轴的应力场、位移场,结果表明强度及符合要求。并在固定扭矩下进行了预应力模态分析,通过对振型分析,可以有针对性选择电机转速,从而较好避免共振的频率范围。对矫直机万向联轴器的选型、设计具有一定的指导意义。A certain type of straightening machine universal coupling static mechanics and modal analysis,the application of ANSYS software to establish a universal shaft finite element analysis calculation model,analysis and calculation of the universal shaft and cross shaft stress field,displacement field,the results show that the strength and meet the requirements.And in the fixed torque under the pre-stress modal analysis,through the analysis of the vibration pattern,can be targeted to select the motor speed,so as to better avoid the resonance of the frequency range.The selection and design of the universal coupling of the straightening machine has certain guiding significance.
