Analysis Of Mechanical Properties For UAS30 Hybrid Arm Type Aerial Vehicle And Structural Optimization Of Its Chassis

The hybrid arm type aerial vehicle is a kind of important engineering crane,which is developed on the basis of folding and telescopic high-altitude vehicles.Compared to traditional folding and telescopic high-altitude vehicles,the hybrid arm type aerial vehicle has the advantages of greater working range and working height,widely used in high-rise building maintenance and municipal maintenance,etc.With the rapid development of economy,the demand for high-altitude operating vehicles is increasing year by year.Therefore,it is of great academic value and application value to carry out mechanical properties and structural optimization of hybrid arm high-altitude operating vehicles,its purpose is to improve its safety and stability.Based on the structure and mechanical characteristics of aerial vehicle,its analytical mechanics model is established,important parts connected to the hinge point load was deduced,for the subsequent finite element simulation model provides the basis.Based on the APDL parametric design language of ANSYS general finite element analysis software,a parametric 3d solid finite element model of the hybrid arm high-altitude operating vehicle is established,and its mechanical properties are analyzed under typical working conditions.The simulation results of the hinge point force are compared with the analytical results,and the finite element model and its boundary conditions are verified.The stress test is carried out on the product of the hybrid arm,and the results of the finite element analysis are in good contrast with the stress test results,which further proves the correctness of the finite element model.Based on the static analysis results of the hybrid arm type aerial vehicle,some mechanical structure was improved design,without any increase in structural weight under the premise of effectively reduces the structure stress level,the improved design scheme has been applied in the actual product.The theoretical research results and the parametric model established in this paper have laid a theoretical foundation for the research and development of a series of hybrid arm type aerial vehicle.
