A Calculation Method of Carriage Capacity of Mining Dump Truck

Abstract

The invention discloses a method for calculating the capacity of a carriage of a mining dump vehicle. The method comprises the steps of determining a repose angle of movement of materials, building a lateral-lateral profile of a material stack, building a front-back profile of the material stack, determining the height of the upper portion of the material stack, determining the peak outline of the material stack, and calculating the volume of the material stack, namely the capacity of the carriage. The calculation method uses the repose angle of movement of the materials in the process of generating the shape of the material stack, different types of materials have different repose angles of movement, the shape of the material stack in a movement state is finally obtained, and the applicability of calculating the capacity of the carriage is largely expanded. The outline of a calculation model adopted by the method is conical, the top of the calculation model is a platform, so that the calculation model more accords with the actual shape of the material stack, and the reasonability of the stack shape is guaranteed. The method for calculating the capacity of the carriage of the mining dump vehicle can guarantee the reasonability of bearing of the vehicle, fully and effectively utilizes the capacity of the carriage, provides guide basis for the design of the carriage and the whole vehicle, and plays an obvious role in optimizing the performance of products.

Description

technical field [0001] The invention relates to a method for calculating the compartment capacity, in particular to a calculation method for the compartment capacity of a mining dump truck. Background technique [0002] At present, mining dump trucks are mainly used in open-pit mines or earthwork construction to realize short-distance transportation from the mining site to the unloading site. As a functional component for loading and unloading materials, the carriage is faced with the demand of carrying a large amount of various types of materials. Usually, mine users who pursue output and efficiency hope to make full and reasonable use of vehicles to ensure that they are loaded reasonably, neither overloaded nor underloaded. This means that when the application is specified in advance, the mining dump truck manufacturer should give a reasonable stack type estimate to guide the design of the compartment, and at the same time, the position of the center of gravity of the mat...

Problems solved by technology

At present, the calibration of the compartment capacity only depends on the standard SAE J1363—1995CAPACITY RATING—DUMPER BODY AND TRAILER BODY, and this standard only uses the space structure formed by the combination of multiple planes to approximate the material pile, which is not valid when the actual material is loaded. Accurate estimation of capacity and lack of pertinence for different types of materials
