DRIVA Features
DRIVA for Wind | DRIVA for Engine
DRIVA for Wind
Model and simulate full wind turbine drivetrain from the blades to the generator response
Identify and Qualify all Drivetrain Resonances
- Generation and display of Campbell diagrams
- 3D display of mode shapes including visual indication of strain and kinetic energies
- Investigate excitations due to gear meshes in the frequency domain using NVH analysis
Load-Increasing Resonance Analysis
- Perform time-stepping multibody dynamics (MBD) simulation of the whole drivetrain to obtain dynamic response of components to any source of excitation
- Obtain load increasing resonant forces from results
Investigation of Transient Dynamic Loading
Wind turbine certification bodies that adhere to DNV GL guidelines (formerly Germanischer Lloyd – GL) recommend that the simulation model of the full drivetrain be used to analyse transient dynamic loading caused by extreme load cases for:
- Emergency Stops
- Grid Loss
- Gusts
Such transient dynamic loading can be fully investigated using Wind Turbine Drivetrain Dynamics (DRIVA for Wind)
DRIVA for Engine
Predict Dynamic Engine Torques
- DRIVA predicts dynamic torques during engine operation taking into account the complex internal damping that occurs in the drivetrain.
Component Rating
- Generate inertia-adjusted load cases for accurate prediction of component damage / lives arising from complex dynamic component loading that occurs in the engine drivetrain
