FOCUS6의 주요 특징들

블레이드 설계 (Blade design)

FOCUS has a unique tool to model interactively rotor blades in detail.
While defining the blade step-by-step, the 3D interactive visualization gives direct feedback of the design changes.

• Material properties, layer thicknesses and layer sequences can be inspected.

  • - This makes blade modeling in FOCUS user-friendly, with less risk of errors in user input.
  • - The materials are assigned to layers that are put into the blade model. ted module is available.

• The aeroelastic performance of rotor blades can be determined without the need of a full turbine model or a detailed blade design.

• The theoretical basis is the beam bending theory, in which torsional deformation and transverse shear flexibility as well as many aerodynamic and structural dynamic coupling terms for bending and torsion dynamics are included.

• Material properties, layer thicknesses and layer sequences can be inspected.

로터 블레이드 구조해석 (Rotor blade structural analysis)

Advanced beam model approach is used for the following structural analysis:

• Strain and stress based static strength evaluation
• Fatigue analyses in time domain
• Buckling analyses
• Modal analyses
• Tip deflection calculations
• For detailed analyses, a shell element based FEM solver is available.
• All results can be presented both in tabular and graphical form.

풍력 터빈 시스템 설계 (Wind turbine design)

• The module Aeroelasticity II calculates the combined aerodynamic and structural dynamic behavior of a wind turbine in time domain.
• The build-in tower model gives a detailed and well-validated dynamic response of the tower including all mutual interactions with the turbine model up to the aerodynamics of the rotor.
• The rotor aerodynamics are solved on basis of the engineering BEM theory of which the sub-models(for tip-loss, tangential induction, blade-tower interaction, oblique inflow effects, rotational effects) are combined on a physical basis.
• Design load sets calculated and blade structural analyses results are accepted for certification
• The rotor aerodynamics are solved on basis of the engineering BEM theory of which the sub-models(for tip-loss, tangential induction, blade-tower interaction, oblique inflow effects, rotational effects) are combined on a physical basis.
• A built-in PD controller is provided that includes rotor speed filtering and peak-shaving strategy. In addition, dedicated controllers can be linked.
• A tool is provided that generates the input for load cases that are required for IEC or GL load set calculations.
• For this purpose models are available to simulate faulted conditions and emergency situations
• The results are accepted for certification by GL and DNV. The results are accepted for certification by GL and DNV.
• In order to reduce the total turnaround time of load set calculations, load cases can be calculated in parallel on computers with multi-core CPUs.
• Using the job management system, load cases can be calculated in parallel on multiple computers.
• FOCUS6 supports submitting jobs to a dedicated computer cluster for further reduction in turnaround.
