Structural Analysis And Design Optimization Of Lorry-mounted Crane

In recent years,as a new vehicle crane product,it has opened up new application areas outside the truck crane.Truck-mounted crane lifting operations are mainly in small tonnage-based,meeting the engineers and technicians work in a variety of needs.Technical references and use the existing problems of the lorry crane boom were analyzed in this paper.The main contents are as follows:Firstly,Using three-dimensional modeling software build model lorry crane boom.Finite element analysis software simplifies the model,without affecting the mechanical properties of the premise.Statics analysis simulates real work truck-mounted crane appeared various operating conditions.a variety of conditions dangerous sections reasons are analysised.Secondly,Kinetic analysis verifies complete lorry crane jib Model.Work will not produce interference between different components in different conditions.Analysis lifting point velocity,acceleration,displacement changes,as well as telescopic cylinders and cylinder luffing the forces.These analyzes are for the following finite element analysis and optimization design foundation.thirdly,Sectional model lorry crane boom is parameterized and sets a reasonable range of parameter changes.Weight lorry crane jib crane meets the objective function bearing stiffness and strengths requirements.Finding the optimal solution is without exceeding the maximum allowable stress conditions.Truck Crane Telescopic lap length are between the arms to optimize the analysis,based on past experience.Finally,Modal analysis and experiments already are carried out in the lorry crane jib optimized basis.People understand the product's use,and provide the technical basis for future product development.
