ROTORINSA® is a finite element software devoted to the prediction of the steady-state dynamic behavior of rotors in bending.

Main Characteristics

Elements
of rotor
Effects - Characteristics Degres of Freedom (dof)
Shafts The effects considered are:
  • Shear effect
  • Axial force
  • Section inertia
  • Gyroscopic effect
  • Magnetic attraction
Elements of beam in bending
2 nodes with 4 dof
Disks The effects considered are:
  • Inertia
  • Gyroscopic effect
Rigid
1 node with 4 dof per node
Bearings Characteristics of:
  • stiffness
  • damping
variable with the speed of rotation
1 or 2 nodes with 2 dof in displacement per node
Specific elements Defined by the matrices:
  • mass
  • stiffness
  • gyroscopic
  • damping
1 or 2 nodes with 4 dof in displacement per node
