Design Optimization of the Aerial Lift Boom through the Finite-Element Analysis (FEA)

The multi-stage boom consisting of several booms is used in order to develop the aerial platform truck that can be used in a working radius that is higher and safe. Because the length increases compared with the width or the height of the structure, the intensity and rigidity are lowered along with the safety. Accordingly, a countermeasure is needed. Therefore, in this research, when designing of the high ground work difference Boom System, the safety the stress of the considered boom the analyze method and experimental method tries to be evaluated through the comparison. The finite-element analysis(FEA) compared the Strain value which is obtained through the resolution value and actual experiment by using the Ansys,that is the general purpose program, and proved this safety.
