Abstract

This study presents finite element analysis based validation of a new nacelle carrier design. This study consists of understanding of transporting device of a wind turbine nacelle from manufacturing site to installation site. The methods of transporting the wind turbine nacelle and the modes of transportation for domestic road transportation conditions and toppling related issues of nacelle study and to overcome the toppling issue probable solutions are provided. Since the nacelle carrier is made up of fabrication process, the welding stability of the component is calculated. Also the stability of nacelle during transportation is important, since the most of the installation sites of wind turbine generator at hill stations there we cannot find a smooth road for the transportation, hence it is important to calculate the weld strength of the component, toppling angle of the component. The device used for transportation is made up of structural steel and is bulk in size of the cost is also increase, if the component of weight is increases. Hence in this work we are developing nacelle transportation device with weight optimization using finite element analysis method. Various designs concepts are prepared by bench marking compotators turbine. The nacelle carrier is safe for working load & experiences maximum 144 MPa of equivalent stress with minimum stress safety factor 1.41. Welds- Minimum stress factor (SFu) is 1.04 new design of nacelle carrier fulfils the structural strength requirements standard requirement. Weight optimization of nacelle carrier is achieved to 1.5 tonnes.
