Design And Research On Lifting Mechanism Of Utility Vehicles

Utility vehicles is a kind of large engineering machinery equipment, which iscurrently widely used in urban garden construction and has a very broad prospects.Although the domestic research on design and manufacturing of utility vehicle hasmade some achievements, we are still fallen far behind the advanced utility vehicleproducts of foreign countries.Based on the subject “modular multifunctional vehicles in road maintenance”,this article designs a lifting mechanism of utility vehicle, to achieve the aerial workplatform functions of utility vehicles.At the beginning, the article introduces several kinds of structures of liftingmechanism of utility vehicles and the research state as well as the achievements thathave already obtained both at home and abroad. Then it analyzes the character ofaerial work platform products of abroad and the weakness of domestic products.Following, the article focuses on introducing the design of utility vehicles.By using ABAQUS/CAE, the paper conducted the analysis on stress and strain ofarm of force of the lifting mechanism. And these study results are to be used asreference in the design of utility vehicles, for it can verify the most appropriateproject for the design of the arm of force.Besides, the article uses the ADAMS to conduct the dynamics analysis of thelifting structure, in which it demonstrated the highest position and furthest distancethat the working platform could reach and obtained the change curve of displacement,velocity, acceleration, angular velocity and angular acceleration. Through the analysisit is found that the velocity of movement of the working platform is within anacceptable range.In the final section, by optimizing sectional dimensions of the arms of liftingstructure, this study successfully reduces the volume of the arm and in this way savesmaterials.
