A reliable analysis method for estimating large excavator
Jan 01, 2016 · Large excavators such as the mining dragline (Figure 10.1a) and shovel (Figure 10.1b) are used for surface mining to dig and transport overburden [,,,,,,,,, ].Their large size front-end structures can swing either left or right during working. The repeated loading induces the front-end to undergo fatigue loading as a result of significant cracking at welded connections [10,11] and

Dynamics and Control of the Bucket-Wheel Excavator: Part I
Bucket-Wheel excavators (BWE) represent a specific type of complex machine system used in mining technology. During operation, the system is exposed to a number of external forces and disturbances like digging resistances on the Bucket-Wheel that cause transverse, longitudinal, and torsional vibrations.

Integration of digging forces in a multi-body-system model
Jun 30, 2015 · The digging process using an excavator bucket was modelled, with the objective of introducing the interaction with the environment into the multi-body-simulation method. With today's software tools, the dynamic behaviour of complex machinery can be effectively simulated.

Study of Forces Acting on Excavator Bucket While Digging
the excavator digging operation is splits into three modes digging mode I, II and III. Digging mode I: This mode includes the penetration of bucket into soil. Bucket teeth's and the toe plate are the two parts which comes in contact with the soil during this mode. This mode is referred as penetration mode.
