Abstract

The invention relates to a tiebar fatigue life prediction method and device, equipment and a computer readable medium. The method comprises the steps that a finite element analysis result, a target relation curve and an actual working condition load spectrum of a target tiebar are obtained, wherein the finite element analysis result is obtained by simplifying features of the target tiebar through a finite element analysis model and conducting finite element statics analysis, and the target relation curve is a relation curve between the stress amplitude level borne by the target tiebar in the actual working condition and the stress cycle index experienced by the material of the target tiebar when fatigue failure occurs under the stress amplitude level; and the finite element analysis result, the target relation curve and the actual working condition load spectrum are input into a fatigue life prediction model according to preset configuration to obtain a fatigue life prediction result of the target tiebar output by the fatigue life prediction model. The technical problem that the fatigue life of the tiebar is inaccurately analyzed is solved.

Description

technical field [0001] The present application relates to the technical field of high-end manufacturing equipment, and in particular to a method, device, equipment, and computer-readable medium for predicting the fatigue life of a Corinthian column. Background technique [0002] The all-electric injection molding machine belongs to high-end manufacturing equipment. In practical application, it must have good stability and low failure rate, that is, the injection molding machine should have a long service life. During the process of opening and closing the mold of the all-electric injection molding machine, the clamping force generated is mainly borne by the Gelin Zhu. The Gelin Zhu is prone to fatigue damage in actual working conditions, resulting in structural damage and failure, thereby increasing equipment failure rate. [0003] At present, in related technologies, experimental methods can be used to analyze and design the fatigue life of Corinthian pillars. However, due...
