Modeling and simulation of folding-boom aerial platform vehicle based on the flexible multi-body dynamics

Folding-boom aerial platform vehicle is a type of construction vehicle used to hoist personnel to the appointed location in the aerial. As for aerial platform vehicle, the flexible deformations of the arm system cannot be neglected. Therefore, the flexible multi-body dynamics equations of the arm system of folding-boom aerial platform vehicle are established based on flexible multi-body dynamics theory and Lagrange´s equation. Following, the simulation is carried out. The simulation results show that the moving beams exist high frequency vibrations, which caused by the elastic deformations of them. As a result, the vibrations cause the work platform of aerial platform vehicle to shake, and at the same time, the deflections of the beams lead to small deviations of the trajectory of the work platform. Therefore, the establishment of the equations lays the basis of vibration controlling and accurately controlling the trajectory of the work platform of aerial platform vehicle.
