EJ-Projects has licensed AnalySwift’s VABS software for use in simulating composite rotor blades.
Based in the Netherlands, EJ-Projects is an engineering consultancy with a primary focus in aerospace, turbo-machinery and wind power technologies. It has licensed VABS for composite rotor blade analysis projects, including an offshore wind turbine project.
“We have had a relationship with EJ-Projects for some time and have been impressed with the work they have done, particularly in composite rotor blade analysis,” says Allan Wood, President and CEO of AnalySwift. “VABS provides a uniquely rigorous solution general-purpose cross sectional analysis tool for computing beam sectional properties and recovering 3D fields of slender composite structures. This includes composite helicopter and wind turbine rotor blades, as well as other slender composite parts, such as landing gear, propellers and high-aspect ratio wings.”
EJ-Projects uses VABS together with GEBT, an open source companion code to VABS, in design analysis focused on rotor blade dynamics. Together with industry standard integrated load analysis software, the company also employs VABS for design and certification of offshore wind turbines.
“VABS is capable of rigorously decoupling an original 3D slender solid with complex cross-sections into a simple engineering beam model,” according to Dr Wenbin Yu, CTO of AnalySwift. “With continuous development funded by the US Army spanning over 20 years for performance and robustness, VABS' accuracy has been extensively verified by its developers and users.”
Chomarat has invested in a new carbon multiaxial machine to bolster its development strategy, particularly in the aerospace and automotive sectors.
Sustainability as a key driver for the use of composites, and the need for life cycle assessment (LCA) methods that provide reliable, reproducible results, were highlighted during the recent Lightweight, Durable and Sustainable Composites seminar organised by the European Composites Industry Association (EuCIA). A video of the event is now available to view online.
On 20 October, the first LM 73.5 P wind turbine blade, the largest blade ever produced and transported through Spain, arrived at Castellón Port.
