There are three main layout forms of the boom system of aerial work vehicle:
One, folding arm structure: the working height of less than 30 meters of the working car generally adopts this structure, such as Xuzhou Helenzhe company XHZ5112JGKKB type aerial working car.
Two, telescopic boom structure: the working height between 30 meters and 40 meters of the working car generally adopts this structure, such as JLG 600S type aerial working car.
3. Folding and telescopic hybrid structure: the working vehicle with a height greater than 40 meters generally adopts this structure, which is mainly telescopic, supplemented by folding, such as the S81HLA type aerial working vehicle of Bo Lentao Company.
A pair of jib system hinge point optimization can introduce the dynamic characteristics of the luffing mechanism as the optimization objective, making the movement of the luffing mechanism more reasonable.
Second, the details of the boom structure are further optimized, such as the thickness of the connecting rod, the plate and the position of the slide block, so that the boom structure is more reasonable.
Thirdly, the control system of aerial working vehicle is studied to make it have real practical application significance.
