Abstract

The invention discloses a data driving-based wear prediction and lining plate optimization layout of a lifting container lining plate. Lining plate wear prediction adopts a discrete element and finite element fusion simulation method, dynamic random optimization is realized, and regional analysis for improving the wear performance of the container lining plate is carried out; and based on the real wear rate of each wear material, a geometric Brownian motion+MCMC method is adopted, and the wear degradation behavior of each grid micro-unit of the lining plate is modeled and predicted. According to the lining plate optimized layout, related data are obtained through lining plate abrasion prediction, and a clustering method is adopted to comprise the steps of: carrying out optimized division of lining plate areas; and selecting lining plate materials in each region and determining the thickness of the lining plate by taking the light weight of the lining plate as a design target and a lining plate failure threshold value as a constraint condition. The wear condition of each lining plate of the metal mine hoisting container can be effectively predicted, the total weight of the lining plates is reduced, the service life of the lining plates is prolonged, the replacement frequency of the lining plates is reduced, the machining efficiency is high, and the machining cost is low.

Description

technical field [0001] The invention relates to the technical field of lifting containers, in particular to data-driven prediction of lining plate wear of a lifting container and optimized layout. Background technique [0002] Metal ore lifting container, because the metal ore has a sharp angle and high hardness and density, the lining plate is impacted by the ore flow during loading and unloading, and the lining plate is affected by the sliding wear of the ore during unloading, which makes the lining plate of the skip bucket wear very seriously , the effective service life is short. In the actual application of engineering, the liner is frequently replaced, which increases the maintenance time of the product. [0003] At present, the commonly used method is that the manufacturer increases the thickness of some liners based on experience to prolong their service life. However, this method increases the total weight of the liner, which reduces the lifting efficiency. At pr...
