Wind Turbine Gearbox Vibration

摘要

Jari Toikkanen, manager of the research and test group at Moventas, a tier one wind turbine gearbox supplier, has seen the number of noise and vibration tests ordered by wind turbine original equipment manufacturers quadruple in the last five years, with many projects requiring same-day turnaround. Particular attention is focused on studying vibrations of the wind turbine's gearbox, which uses a combination of planetary and helical gearing to step-up rotor speed 100-fold for driving the electrical generator. Moventas worked with LMS Engineering Services to measure gearbox rotational vibration on the low-speed input and high-speed output shafts for a wind turbine manufacturer.
