Optimum Design of Kitchen Garbage Truck Lifting Mechanism Based on Virtual Prototype

The lifting mechanism's mechanical system and hydraulic system were built by the mechanical system dynamics software ADAMS for improving the mechanism's performance. The hydraulic-mechanical virtual prototype model was established by the integration of the two systems through parameter correlated technology under ADAMS environment. The locations of revolute joints were optimized with the minimum of the cylinder forces as the optimization goal, by using the OPTDES-GRG and the main design points were parameterized. The optimization results show that the maximal cylinder forces had reduced by 16.5% over the non-optimum one, while the lifting force has reduced by 15.7% in the work process of lifting mechanism.
