LOAD ANALYSIS OF THE ARTICULATING BOOM SECTIONS OF THE MOBILE ELEVATING WORK PLATFORM IN RELATION TO THE OPERATOR BASKET POSITION

Abstract

The structural analysys of typical mobile elevating work platform articulating boom, moving quasi-statically in the vertical plane, has been carried out. Along with certain approximations, a model for calculating the load transmission from basket to the support on the vehicle chassis has been developed. Thus, it made possible to track changeable load conditions of every structure element, as well as to track force changes in hydro cylinders, depending on boom joints’ angles and geometric parameters of the boom sections. Analytical forms of boom sections load and hydro cylinders forces enable the optimization of the characteristic boom sections dimensions, cross-sections parameters and hydro cylinders abutment points position. In addition, obtained functions can be used for hydro cylinders and hydro pumps workflow control.
