Response Calibration and Correction of Large Megawatt Wind Turbine Gearbox Dynamics Model
Abstract
Reliable dynamic simulation model is an important means of vibration improvement. Taking the dynamics model of 5.2 MW wind turbine gearbox bench transmission chain as an example，the dynamics modeling，response evaluation and calibration are described based on the empirical modeling methods in the industry. Based on the sensitivity optimization method，the gear meshing dynamics model is corrected，and the vibration response accuracy of the corrected dynamics model is better，indicating that the empirical modeling method combined with the sensitivity optimization method can establish a relatively reliable dynamics model，and it is an effective method.
