MODELING AND ANALYZING THE DYNAMICS OF ARTICULATING BOOM LIFTS WHEN OPERATING IN COMBINATION TO LIFT THE LOAD

An articulating boom lift is used to perform work in high and difficult-to-reach locations. Dynamic stability is extremely important during the deployment and operation of an articulating boom lift. Therefore, this article builds a model and investigates the dynamics of an articulating boom lift when simultaneously performing operations during the lifting process to serve as a basis for determining the vehicle’s dynamic stability. The dynamic model considers the elasticity and damping of the hydraulic cylinders used for lifting the loads. The Lagrange equation of type II is used to build the system of differential equations describing the motion of the mechanical system. Based on this model, the article investigates the dynamic parameters when the forklift performs multiple operations for lifting objects. The results of the article are the basis for the control problem of the forklift, aiming to enhance its performance and reliability during operation.
