GL Renewables Certification has certified the engineering software nCode DesignLife. The structural integrity software for the fatigue calculations of cast and forged structural machinery components in wind turbines has been evaluated on the basis of GL RC’s Guideline for the Certification of Wind Turbines 2010.
The turbine mainshaft has been analyzed in nCode DesignLife for its fatigue life. The software has been certified by GL Renewables Certification.
“The certificate proves that the software is suitable for the calculation of fatigue life of forged and cast structural machinery components of wind turbines, “says Mike Woebbeking, Vice President and Head of Certification Body, GL Renewables Certification. It assures users that their component designs can be analysed in conformity with GL RC’s Guideline for the Certification of Wind Turbines 2010.
This includes fatigue analysis under complex real-world loading conditions specified in GL RC’s guidelines or IEC 61400-1 international standard. The evaluation is based on parallel calculations of intermediate and final results considering different stress hypotheses and influence factors for survival probability, cast quality, surface finish, and mean-stress correction.
The software, nCode DesignLife, for fatigue analysis, works well with large models and realistic loading schedules. The developer says its advanced fatigue solver lets wind turbine manufacturers identify when and where failure could occur in a casting using complete loading duty cycles representing the full 20-year loading events experienced in service.
