Multi-Objective Dynamic Optimum Design of Crane Gearbox

Abstract:

The lower vibration and lightweight design is of great significance to large mechanical equipment. In order to achieve the best dynamic performance of cranes, this paper presents a multi-objective optimization approach based on finite element method. Firstly, the finite element model of coupling system consist of gear-rotor-bearing-housing is established. Subsequently, the transient response of the gearbox is studied using modal superposition method. Then with the purpose of reducing the vibration and preventing sympathetic resonance, a multi-objective optimizer is developed by employing a parametrical design language and obtained the optimal combination of design parameters after several iterations. The method and conclusions can be used as a reference of dynamic modification of large machineries.
