On Nonlinear Dynamics of Dragline Bucket Subjected to Flexible Linkages
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2014, Vol 11, Issue 2
Abstract
In this paper, the oscillatory motion of the dragline loaded bucket it was highlighted. Hence, the authors proposed a new computational model useful for study of the nonlinear dynamics of the bucket. The linkage of the bucket, consist on hoist rope, it was modelled as flexible element. Hereby, the hoist rope – bucket system provides the pendulum movement of the bucket on horizontal direction, and linear oscillations such as single degree of freedom vibratory system on vertical direction. The numerical simulations, implemented in MAPLE software, show that the trajectory of the mass centre of the bucket is directly influenced by the each structural element motion which compose the proposed model.
