Dragline Bucket and Rigging Dynamics
نویسنده
چکیده
This paper is a continuation of work originally undertaken by the authors which predicts the static pose of a 1:20 scale dragline bucket and rigging throughout its workspace. Based on the results of this prior work, a two degree of freedom pendulum model is used to describe the dynamic response of the bucket to a small velocity inputs of the drag-rope. Linear differential equations, valid for small perturbations about the equilibrium pose, are used to predict the change in drag-rope tension and angular velocity of the bucket. Experimental frequency responses of these force and velocity transfer functions are used to confirm the mathematical model.

Development of a Dragline In-bucket Bulk Density Monitor
This paper details the implementation and trialling of a prototype in-bucket bulk density monitor on a production dragline. Bulk density information can provide feedback to mine planning and scheduling to improve blasting and consequently facilitating optimal bucket sizing. The bulk density measurement builds upon outcomes presented in the AMTC2009 paper titled ‘Automatic In-Bucket Volume Estim...
متن کاملComparison of measured and simulated motion of a scaled dragline excavation system
Motion measurements obtained from a maneuvering 1/16-scale dragline excavation system using a six camera motion capture system are compared against motion predictions of the same scenario using a complex dragline excavation system simulation. The dynamic model includes motion of the bucket, spreader bar, hoist cluster, and drag cluster, along with flexible rope and chain segments including the ...

(2)H-(13)C HETCOR MAS NMR is performed on (2)H/(13)C/(15)N-Pro enriched A. aurantia dragline silk. Proline dynamics are extracted from (2)H NMR line shapes and T1 in a site-specific manner to elucidate the backbone and side chain molecular dynamics for the MaSp2 GPGXX β-turn regions for spider dragline silk in the dry and wet, supercontracted states.
متن کاملSecondary Structure Adopted by the Gly-Gly-X Repetitive Regions of Dragline Spider Silk
Solid-state NMR and molecular dynamics (MD) simulations are presented to help elucidate the molecular secondary structure of poly(Gly-Gly-X), which is one of the most common structural repetitive motifs found in orb-weaving dragline spider silk proteins. The combination of NMR and computational experiments provides insight into the molecular secondary structure of poly(Gly-Gly-X) segments and p...
