A customized finite element analysis software for windmill blades
- Stanford Univ., CA (United States). Dept. of Aeronautics and Astronautics
Analysis and design of windmill blades can be made user friendly when sophisticated software is customized for a particular boundary-value problem. Specific example of how this is accomplished will be illustrated using a commercial software package. Material and orientation of composite materials can be easily defined. Blade geometry can be imported from CAD files. Several meshing options can be easily selected. Linear analysis models for strength and deformation, vibration and buckling can be calculated. Post processing of element strength or safety factor within each ply can be graphically displayed. It is the intent of the customized software that minimum training is required before users become proficient. This is accomplished through extensive use of menus, dialogue boxes and other graphic options. Relying primarily on a mouse, key strokes are kept to a minimum which enhances the retention of training. Other user oriented features are being introduced to further speed up the operation of the Software. It is believed that with simplified user interface that training that lasts several days can be significantly reduced. Many more engineers will be attracted to modern design to achieve the structural performance and cost effectiveness inherent with composite materials.
