Simulation Analysis And Optimization Design Of Side Loading Type Garbage Truck Multifunctional Manipulator

With the process of our country’s urban modernization and township urbanizationsignificantly accelerated，the amount of municipal solid waste was increasing. Theawareness of environmental protection had given rise to the introduction of morenational and local environmental policies, and then promoted a rapid innovation anddevelopment of the automatic garbage collection system. The existing collection modeis low efficient and high labor intensity. Especially, the refuse collecting station ortransfer station have a direct impact on the quality of the urban environment andconstruction. However, foreign garbage truck usually had the half automation design,automatic crawl into trash and garbage carriage, realize intelligence collecting garbagevehicle. Yet higher requirements has been put forward for the design of intelligentmanipulator garbage truck, and for the automatic recognition of the garbage bin and itsmechanical arm strength and stiffness design has new requirements. Therefore, at thesame time in the study of side loading garbage truck multifunctional manipulatorintelligent parameter design, hands on mechanical strength and stiffness has beenverified and on this basis the optimization design has been put forward.Firstly, based on the manipulator kinematics and dynamics on the theoreticalanalysis, establish the model of the virtual simulation manipulato using ADAMS.Weanalysis the process of the manipulator grabbing the dustbinin various typical operatingconditions.Then we obtain the corresponding clamping force, support reactions andhydraulic cylinder driving forces of the manipulator’s composite motions. Finally, weverify the simulation data by statics theory.Then utilizing the workbench software to establish finite element model of the railmanipulator, we acquire stress and deformation nephogram by the finite elementanalysis in various typical operating conditions，then check the static strength andrigidity. Certain basis has been provided on this basis for the later manipulatoroptimization design.Finally, based on the workbench platform, combine the orce analysis mechanicalhand and the optimization design，the structure of the manipulator has been improved tocater to the trend of the lightweight design. And make a stress analysis of the afteroptimization compared with before, meet the design requirements.
