description The invention relates to the technical field of automobile parts, in particular to a fatigue strength checking method for a TVD hub, and the method comprises the steps: obtaining a finite element model of a crankshaft torsional vibration damper TVD, a first fatigue working condition of the TVD hub, a second fatigue working condition of the TVD hub, and material parameters of the TVD hub; according to the first fatigue working condition, the second fatigue working condition and the material parameters, fatigue strength simulation processing is conducted on the finite element model, and the target fatigue safety coefficient of the TVD hub is obtained; if the target fatigue safety coefficient is not smaller than the fatigue safety coefficient threshold value, it is determined that the fatigue strength of the TVD hub reaches the preset fatigue strength, and information of the fatigue strength of the TVD hub is output. According to the method, comprehensive fatigue strength simulation analysis is carried out on th
