Abstract

The invention provides a method and device for predicting the abrasion loss of a mixing drum and a readable storage medium. The mixing drum abrasion loss prediction method comprises the following steps: establishing a mixing drum model; establishing a calculation area for the mixing drum model, and dividing the calculation area into grids; generating a concrete particle model; setting attributes and parameters of the mixing drum model and the concrete particle model; based on the attributes and the parameters, performing discrete element simulation on the grids; selecting a monitoring area, and obtaining the abrasion loss of the monitoring area. In the technical scheme of the invention, the wear condition of the mixing drum is predicted by adopting a discrete element simulation method, the calculation speed is high, the setting is simple and convenient, the time and labor are saved, and the wear condition of the mixing drum can be predicted in advance.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a method, device and readable storage medium for predicting the amount of wear of a mixing drum. Background technique [0002] At present, concrete is widely used in daily life and production. With the development of concrete production and wide application, the method of centralized concrete mixing and on-demand supply has gradually formed. Concrete is produced by mixing plants and then transported to various places by concrete trucks. [0003] The wear resistance of the mixing drum determines its service life to a large extent. When a certain part first wears out and fails, the mixing drum must be stopped for maintenance. It is inefficient to improve the process parameters of the mixing drum only based on experience, and the effect cannot be accurately predicted. At present, there is no such method that can predict the wear resistance of the mixing drum. Contents of th...
