In this paper, the boom of a 30m class refracted insulation with outrigger on aerial elevating work platform is modeled as 3D CAD program of CATIA. The static and dynamic analyses are performed by using ANSYS and ADAMS programs, respectively. The refracted insulation boom uses acetal and the composite boom for insulation. And the composite insulation boom is modeled by using ACP (Ansys Composite Prepost) of ANSYS program. In order to analyze the durability of refracted insulation boom, the static analysis is performed and each analyzed part is stored as =MNF-type flexible body model. The dynamic analysis is performed with ADAMS by using the flexible model. As the result, these analyzes clarify the structural stability and dynamic durability (hot spot) of the refracted insulation boom.

The aim of this paper is to clarify the structural stability of Refracted Telescopic Boom in 30m Class with the Property of Working Range Insulation. The boom of insulation special vehicle consists of a 3-stage telescopic boom, 2-stage refracting boom, insulation boom and effector. The catia solid geometry of the boom was used to generate both a basic ADAMS model and the finite element meshes for the flexible components. The flexible bodies were generated by using the finite element program of ANSYS and then imported into the ADAMS model and their flexibility accounted to the dynamic analysis of boom. Embedding finite element representations within the ADAMS model, offers the advantage being able to perform the durability analysis and the resulting damage. Through this approach, the crack locations(hot spots) in a prototype can be predicted successfully, thereby validating the analysis procedure.

When working on electrical wiring and cable, Electrically insulated aerial work platforms must be used to prevent the electrocution hazards. Aerial work platforms with composition boom is able to increase the weight and height of the workspace due to the lightweight of boom. The aim of this paper is to clarify structural stability of 3 stage telescopic booms having an operator platform and an upper boom of composition(Fiber Reinforced Plastic) by comparing the general telescopic booms with steel material using computational analysis.
