Planned periodic or unplanned maintenance should be implementedat wind turbine in order to maintain structural integrity of the windturbine during design lifetime. The previous maintenance have beenmainly performed by using tools such as crane and gondola. But, it
is impossible to inspect and repair tower and blade simultaneously
with these tools. So, recently, the maintenance stand has been developed to overcome the problem. It is required select safe configuration and materials of the stand design safe maintenance
stand.
In this study, structural integrity of the present maintenance stand was assessed via finite element analysis. As a result, most of parts satisfy the design requirements but some parts do not satisfy. So,all the parts have been redesigned to maintain structural integrity
under the design conditions through repeated processes of finiteelement analysis and modification.
