Abstract

The invention discloses a method for predicting wear of a lining plate of a lifting container and a method for optimizing the layout of the lining plate. The liner wear prediction method adopts the discrete element and finite element fusion simulation method to realize dynamic stochastic optimization, and conduct regional analysis to improve the wear performance of the vessel liner; based on the real wear rate of each wear material, the geometric Brownian motion + MCMC method is used to The wear degradation behavior of each grid micro-unit of the liner is modeled and predicted. The method of optimizing the layout of the liner uses the relevant data obtained from the wear prediction of the liner, and uses the clustering method to optimize the division of the liner area; with the lightweight of the liner as the design goal, and the failure threshold of the liner as the constraint condition, the lining of each area is carried out. Selection of plate material and determination of lining thickness. The invention can effectively predict the wear condition of each liner plate of the lifting container for metal mines, reduce the total weight of the liner plate, improve the service life, reduce the replacement frequency of the liner plate, and has high processing efficiency and low processing cost.

Description

technical field [0001] The invention relates to the technical field of lifting containers, in particular to a method for predicting wear of lining plates of a lifting container and an 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. ...
