An evaluation method for the remanufacturing access period of construction machinery jib structures

Abstract

The invention relates to a method for evaluating the remanufacturing access period of an engineering mechanical arm rest class structure. The method comprises the specific steps of a, formulating an evaluation criteria of a solid web type arm rest failure mode, b, correcting and perfecting a parameterized finite element model and a simulation computing platform, c, setting up the performance under the remanufactured arm rest typical service working condition, namely, a database of the failure form, d, conducting traceability analyzing on the failure form and the main influence factor, and e, predicating the residual service life of an arm rest, and forming the remanufacturing arm rest access period evaluating method. The computer virtual simulation technology is utilized by the method, an expert evaluation system of an arm rest class structure part is set by processing related measured data, and the system is used for evaluating the residual life and the related technical index of the arm rest class structure.

Description

technical field [0001] The invention relates to the field of mechanical design and manufacture, in particular to a method for evaluating the remanufacturing entry period of an engineering machinery boom structure. Background technique [0002] At present, my country has a huge amount of construction machinery and equipment with many types, but the product quality is at the international second-rate level, which is reflected in the relatively low reliability and life of the product, many early failures, and the appearance and surface quality need to be improved. With the increase in the number of scrapped With the continuous increase, 80% of the construction machinery in service has reached the overhaul period, plus typical, large-scale, expensive and other mechanical equipment and parts, there is an urgent need for the development of remanufacturing and reuse technologies. Therefore, it is imperative to carry out remanufacturing of construction machinery, and the potential is...
