Our range of services for you

The scope of work for JHS in the design process is the following:

  • Review of received input data
  • Determination of number, type and distribution of calipers
  • Determination of number, size and distribution of yaw drives (if changes are needed)
  • CAD modelling of yaw brake disc and possible changes to the main frame
  • Setting up a global FEM model of the complete wind turbine in order to determine the deformations and resulting loading on calipers, pads and bolts
  • Strength assessment of the following components:
    • Yaw brake calipers
    • Main frame
    • Yaw brake disc
    • Bolted connection between calipers and main frame
    • Lower, upper and radial brake pads
  • Verification of yaw drives and yaw pinion
  • Creations of specifications of the affected machinery components (yaw drives and pinion) and bolts (size, number, type, pretension level and tightening method)
