Beskrivelse
This book has applied virtual prototype technology to model and simulate cable shovel for system dynamics and structural dynamics analysis in engineering applications. A rigid virtual cable shovel prototype is developed in a virtual mining environment for automatic dynamic analysis of shovel mechanical systems. The kinematics and dynamics embedded in this model are established as a right multi-body system based on the Euler-Lagrangian equations. The control system models are designed for driving the virtual model in real-time to track a desired time-based trajectory. By simulating the virtual prototype, the large structural cable shovel is visualized and system dynamics performance is captured. The dynamic virtual prototype model is validated by the comparison of the simulation results with the experimental analysis results. For the purpose of structural dynamics analysis, a hybrid cable shovel virtual prototype is generated by integrating flexible parts into the rigid components based on the theory of flexible multi-body dynamics. Three case studies are demonstrated from hybrid virtual prototype modeling through dynamic stress and deformation simulation to fatigue life evaluation. The structural dynamics performance of a cable shovel in oil sands formation is examined in a virtual simulation environment. The simulation model is validated by comparing the dynamic analysis results with the field test analysis results. This book is technically thorough, complete and consistent based on the existing knowledge, advanced technology and validated experience within academia and industry. It provides appropriate methodology from cable shovel detailed modeling and simulation to examination and analysis for researchers and engineers. Ying Liliyinglzh@yahoo.com
