Optimization of a Loader Mechanism on the Basis of the

Jul 31, 2018 · The paper defines the directed digging force as a criterion for the optimal synthesis of loader mechanisms. The directed digging force is defined on the basis of the following: boundary digging forces permitted by the stability of a loader, boundary digging forces enabled by loader mechanisms, and factors related to the digging position in the working range of a loader …

Improving Point Cloud Accuracy Obtained from a Moving

Oct 01, 2013 · We present a perception system for enabling automated loading with waist-articulated wheel loaders. To enable autonomous loading of piled materials, using either above-ground wheel loaders or underground load-haul-dump vehicles, 3D data of the pile shape is needed. However, using common 3D scanners, the scan data is distorted while the wheel …

Effectiveness of Similitude Theory for Bucket Design and

Oct 06, 2021 · This paper evaluates the effectiveness of similitude theory in predicting the draft of a rubber tire loader's bucket during initial penetration. The work uses 1:16 and 1:8 scale models of an 18-t capacity load haul dump, scaled with the Buckingham Pi Theorem, to evaluate the prediction of draft and penetration under different operating and different dynamic conditions. …

A study on automatic control of wheel loaders in rock/soil

In this controller, a digging task is decomposed into three sequentially implemented operations: attacking, crowding, and scooping; each of them can be carried out with different strategies. An ideal trajectory is pre-generated based on the physical property of the wheel loader and rock pile, and is generally followed during the digging process.
