Simulation Analysis And Key Components Lightweight Of Food Garbage Truck Lifting Mechannism

In the kitchen garbage truck market,side-mounted compressed kitchen garbage trucks have a market share of up to 56%due to the advantages of large loading capacity,low freight per ton of garbage,convenient operation and high safety.The lifting mechanism is the core component of the kitchen garbage truck,and its kinematics,dynamic characteristics and structural strength directly affect the efficiency of garbage loading.At present,the lifting mechanism of the domestic side-mounted compressed kitchen garbage truck generally has the disadvantage of greater quality than foreign products.Therefore,the analysis and optimization of the lifting mechanism has certain practical significance and practical value for reducing production costs,energy saving and emission reduction..The research work of this article mainly includes:(1)Material lifting mechanism design modeling and kinematics and dynamics simulation analysis.According to the use characteristics and technical requirements of the kitchen garbage truck,the material lifting mechanism is designed,the three-dimensional solid model is established,and the virtual assembly is performed to check the interference and symmetry of the material lifting mechanism.Perform kinematics and dynamics simulation analysis on the lifting mechanism according to its working principle and actual working conditions,and obtain the displacement,velocity,acceleration curve of each key component of the lifting mechanism in the movement process,and the force of the associated hinge point,and get The dangerous working conditions of tie rod bracket,bucket bracket and connecting rod provide basic data for subsequent mechanical analysis.(2)Mechanical analysis and lightweight design of key components of the material lifting mechanism.Perform mechanical analysis on the pull rod bracket,bucket bracket and connecting rod of the lifting mechanism,obtain stress and displacement cloud diagrams,check whether the rigidity and strength meet the requirements,verify the rationality of the structural design,and provide a basis for its lightweight design.According to the finite element analysis results,first use the shape optimization design module of Ansys Workbench to optimize the shape of the tie rod bracket and the hanging bucket bracket,remove the excess material,and then select the main size as the optimization design variable,and establish the optimization target with mass,stress and displacement.The response surface optimization model,after a two-stage composite optimization,reduces the mass of the tie rod bracket,the hanging bucket bracket and the connecting rod,and realizes the lightweight of the lifting mechanism.(3)Trial-production and test of the sample vehicle.According to the optimized parameters,the sample vehicle is trially-produced,and various tests of the lifting mechanism are carried out under the actual loading condition.The results show that the improved lifting mechanism runs smoothly,works reliably,and its comprehensive performance meets the design requirements.The research results of this paper can be used in the production of related products in enterprises.
