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.

2.2.2 Design The butt weld is normally designed for direct tension or compression. However, a provision is made to protect it from shear. Design strength value is often taken the same as the parent metal strength. For design purposes, the effective area of the butt-welded connection is taken as the effective length of the weld times the throat

force analysis of mini hydraulic excavator attachment. The objective of this paper is to design an excavator bucket to get smooth flow of material and to get effective digging forces. Key Words: bucket gets damage due to some improper handling by the Excavator, optimization, bucket volume calculation, stress analysis.

The excavator arm includes three parts: the boom, the stick, and the bucket. Figure 1. Block diagram of the excavator [16]. One of the requirements for excavator during working process is that the weight of material after each excavating period should be within acceptable range to optimize the efficiency.

Dec 01, 2018 · The other way is to install Marker 2 rigidly on the object (in this case, the stick of the excavator), and pre-calibrate the pose of Camera 2 in the project coordinate frame. As long as Camera 2 (or Marker 1) stays static in the project coordinate frame, the pose of the excavator's stick (or the cabin) can be estimated in real-time.

Apr 03, 2018 · Without including the uncertainty effects in the design procedure, the designs may not be robust and reliable. Robust design optimization (RDO) method is a procedure to find the insensitive design with respect to the variations. On the other hand, reliability is measured by the probability of satisfying a specific design criterion.

Feb 08, 2019 · The aim of this article is to establish the design process of a new long reach boom for the Caterpillar excavator (CAT 375) for dredging in harbors and dams. The length of both the boom and the stick in extended mode can reach up to the maximum digging depth of 17.2 m. The capacity of the bucket for this new model of long reach boom is 0.8 m3.
