Since electric energy is used in industry, mass production and various conveniences are provided. To provide convenience for the construction and operation of such electric energy transmission and distribution facilities, it is increasing that the demand for special purpose vehicles, that is, telescopic aerial work platform vehicles. When working active electric work using the telescopic aerial work platform vehicles, due to active electric work is inevitable, it is essential to ensure insulation performance for the safety of the operator. In this paper, we study the design and development of mechanical properties for filament winding process of glassfiber/epoxy composite, it is required to boom of telescopic aerial work platform vehicles. The glass fiber/epoxy composite filament winding process and its mechanical properties were evaluated to replace the existing ATOS80 boom. By filament winding process it was obtained the mechanical properties required for the design analysis of the glass fiber/epoxy composite boom. Using this, the insulated boom for the 30m class aerial work vehicle was designed and was manufactured by applying the filament winding process. The fabricated composite boom was evaluated by the static strength test to meet the required strength. The maximum displacement was 84mm and the crack occurred at the maximum load of 8981N. It satisfied the maximum lifting load of 4900N and 210mm the maximum displacement required for the boom.

Due to rapid industrialization and urbanization, maintenance of high voltage transmission lines in narrow alleys, complex roads, or old factory areas is required. Since the existing aerial lift vehicle is made of steel, there is a risk of electric shock. Therefore, there is a need for the development of an insulated aerial lift vehicle that can prevent electric shock accidents during electrical work. In particular, the development of an insulated aerial lift vehicle is required in a recent work environment where live line work is inevitable. The development of composite insulation boom for the vertical swing type aerial lift vehicle is studied. The insulated boom was developed by applying glass fiber-epoxy composite and filament winding process. The developed insulated boom was verified by measuring dielectric breakdown strength, surface resistance and volume resistance according to ASTM D149 and ASTM D257.

The aim of this paper is to clarify the structural stability of 30m fly(maximum working radius of 30m) and telescopic boom with composition. In order to reduce the weight and insulate, the boom of special vehicle has a 3-stage telescopic boom of DOMEX960, pocket part of acetal, 2-stage refracting boom of ATOS80, insulation boom of glass fiber composition and effector. In this process, CATIA is applied to create 3D modeling, then ANSYS are performed the structural analysis. The structural analysis is performed for a case where the thickness of the insulating boom of the ATOS 80 is 7[㎜] and the thickness of the insulating boom of the FRP material is 15[㎜] and 16[㎜].

BIRDI(Bridge Inspection Robot Development Inter)ace)에서 현재 개발된 첨단굴절로봇차는 기존의 굴절차에 비해 소형이며, 12m에 이르는 작업붐으로 인해 교량의 진동, 풍하중 등에 의해 쉽게 진동이 발생할 것으로 예상된다. 본 연구에서는 첨단굴절로봇차의 머신비전 시스템을 통한 점검 성능 확보를 위해 작업붐에 엑츄에이터를 장착하여 유해 진동을 제어할 수 있는 시스템을 제안하였으며, 성능 평가를 위해 수치적, 실험적 연구를 수행하였다. 제안된 제어시스템의 수치적 연구를 위해 현재 제작된 작업붐의 제원을 이용하여 모델링하였고, 적당한 주파수 특성을 가진 하중을 가정하였으며, 최적 제어이론인 LQ 조정기를 설계하였다. 수치해석 결과, 제안된 제어시스템은 작업붐에 발생되는 유해 진동을 저감시킬 수 있었다. 실험적 연구를 위해 작업붐의 축소 모형을 제작하였고 제어시스템을 구축하였다. 또한 실험결과 작업붐의 진동을 짧은 시간에 제어하는 우수한 성능을 보였다. 본 연구를 통해 제안된 시스템의 진동제어 성능을 입증하였으며, 실제 첨단굴절로봇차에 적용될 경우 점검 시스템의 성능을 향상시킬 수 있을 것으로 사료된다.
