Aerial Vehicles Kinetic Analysis

When the arm rising or descending suddenly or when the whole vehicle moving or stopping, the aerial working platform vibrates too seriously. So it's necessary that dynamic analysis for aerial working platform be performed. In this article the aerial working platform of straight-arm mode is mainly studied on the basis of Analytical Mechanics, namely the system is described with Lagrange Equations and a mathematical model is built. Then a certain aerial working platform is analyzed and some conclusions have been drawn that the effects on vibration when correlated parameters are changed. During the course of the example computing this paper also discusses how to get the rigid measure of the solid tires, equivalent mass of the boom and equivalent rigid measure of the boom. The study in this article can provide useful theoretical proofs on the design and operation of aerial working platform of straight-arm mode, what's more, the conclusions and the results of this article is prepared for the active control of the vibration. In the paper it gives the deduction of the equations in detail and the programs how to solve them with Matlab.
