Lightweight Optimization of Garbage Collection Truck Manipulator Based on Parametric Modelling

Abstract

In order to improve the performance of garbage collection truck manipulators, a three-dimensional model of the garbage collection truck manipulator is established based on SolidWorks. The dynamic analysis of the garbage collection truck manipulator model is carried out using the ADAMS software according to its movement in different working conditions, obtaining the displacement, force, and speed curves. The model is identical to garbage collection truck manipulators used in real situations. The static characteristics of the garbage collection truck manipulator model are analyzed in HyperWorks, which provides the conditions for the subsequent optimization. Finally, based on parametric modeling, taking the volume minimum as the goa, keeping the deformation and stress to meet the requirements for use as constraints, a genetic algorithm is used to optimize the weight of the manipulator. The optimization results show that the mass of the manipulator can be reduced by 17 kg (16.73%) while the strength meets the requirements.
