To avoid the disadvantages of common optimization methods which only take inner design parameters into account

the study investigated whether the collaborative optimization(CO) can be applied to overall design of a mining truck's hoist system.The framework of CO is introduced and its inherent disadvantages are analyzed.A collaborative optimization method in which the simulated annealing algorithm is used as the search strategy for the system-level optimization is presented.Taking mining truck's body

frame and hoist mechanism collaborative design as an industrial instance

the study created its CO mathematic model and obtained optimal solutions by integrating all disciplinary analysis tools into the iSIGHT software specialized in multidisciplinary design optimization.The result shows that the convergent value of the system-level consistency constraint is zero and the CO method can search global optimal resolution robustly when the simulated annealing algorithm is used as the search strategy of the designed space.
