description The invention discloses an elevator shackle fatigue life design method, and relates to the field of elevator shackles. The problems that an existing elevator shackle is prone to abrasion when bearing dynamic load change, the strength of a product is reduced, and the service life of the product is prolonged are solved. A fatigue life design method for a shackle for an elevator comprises the following steps that S1, the shackle is installed, S2, a pin shaft part is connected with a compensation chain, the line diameter of the compensation chain is printed on the pin shaft part, and the stress of the compensation chain is applied to the area of the pin shaft part, S3, loads which do not continuously bear dynamic force in the elevator running process are subjected to equal-proportion loading calculation, and the fatigue life of the shackle is calculated. S4, according to the circulation limit values, calculation is carried out through finite element analysis software under the quadruple safety coefficient, and th
