Optimal design and implementation of a drivetrain for an ultra-light electric vehicle [PDF]
, 2016 This paper presents an integrated design of a drivetrain for a single-person ultra-light electric vehicle (ULEV). To calculate losses and efficiency of the inverter, the permanent magnet synchronous machines (PMSMs) and the gearbox, parameterised ...

Techno-economic comparison of operational aspects for direct drive and gearbox-driven wind turbines [PDF]
, 2010 The majority of wind turbines currently in operation have the conventional Danish concept design-that is, the three-bladed rotor of such turbines is indirectly coupled with an electrical generator via a gearbox.

Modeling of Wind Turbine Gearbox Mounting [PDF]
Modeling, Identification and Control, 2011 In this paper three bushing models are evaluated to find a best practice in modeling the mounting of wind turbine gearboxes. Parameter identification on measurements has been used to determine the bushing parameters for dynamic simulation of a gearbox ...

Novel spectral kurtosis technology for adaptive vibration condition monitoring of multi-stage gearboxes [PDF]
, 2016 In this paper, the novel wavelet spectral kurtosis (WSK) technique is applied for the early diagnosis of gear tooth faults. Two variants of the wavelet spectral kurtosis technique, called variable resolution WSK and constant resolution WSK, are ...

Planetary Gearbox Vibration Signal Characteristics Analysis and Fault Diagnosis
Shock and Vibration, 2015 Planetary gearboxes are widely used in helicopters, wind turbines, mining machinery, and so forth. The structure and motion type of a planetary gearbox are more complex in comparison with a fixed-shaft one, which makes condition monitoring and fault ...

Pattern Formation in Non‐Equilibrium Architected Materials
Advanced Materials Technologies, EarlyView.This article demonstrates an artificial mechanical system ‐ a robotic metamaterial ‐ as an accessible and versatile platform within which to explore and prescribe the reaction‐diffusion driven pattern formation hitherto associated with comparatively less accessible and versatile non‐equilibrium biological and chemical systems.
