Numerical analysis of stresses in mine excavator bucket
Dec 05, 2015 · Excavator plays a vital role in mining industry and bucket is one of its most important components as failure of excavator bucket causes loss of production. In this paper, static analysis of excavator bucket (Tata JD 315SJ Model 2006) made of Hardox 400 alloy has been done. A solid model has been developed in CATIA V5 R18 Software by considering actual dimension of the bucket. The …

Robotic excavator motion control using - …
Apr 01, 2016 · Tiwari provided a way to classify the bucket trajectory; this approach could assist in the operation of excavators. For an excavator, the motion of each actuator is controlled by a separate closed-loop controller, such as neural adaptive control, robust adaptive control, and sliding mode control . However, single actuator control cannot guarantee accuracy for an unmanned excavator.

Path Planning for Excavator Arm: Fuzzy Logic Control …
This paper proposes an algorithm to design the path for automated excavator arm. The path designing is divided into two phases. Firstly, the fuzzy logic technique is used to determine the change of the path to adapt with the variation of the material after each digging period. Secondly, the B-spline algorithm is used to build the optimal trajectory. By this, the excavator can maximize the dug

What are the different types of mining and how do they differ?
Mar 15, 2017 · Utilising the mammoth strength of Bucket-Wheel Excavators, moving up to 12,000 cubic meters of earth per hour, Surface mining is the process of seam mining coal and ore from the land. In this process, any unwanted earth or soil is stripped from the land and any ore or mineral that is sought after is found relatively close to the surface of the

Oct 07, 2019 · This paper presents a methodology for lightweight and high-strength design of an excavator bucket under uncertain loading. Uncertain loads are obtained by using the Monte Carlo simulation based on the existing soil-bucket interaction model in which the soil parameters are variable. And the well-known 3-sigma methodology is used for the quantification of the uncertain loads.
