Computational Design Scheme for Wind Turbine Drive‐Train Based on Lagrange Multipliers

open access: yesJournal of Energy, Volume 2017, Issue 1, 2017., 2017
The design optimization of wind turbines and their subsystems will make them competitive as an ideal alternative for energy. This paper proposed a design procedure for one of these subsystems, which is the Wind Turbine Drive‐Train (WTDT). The design of the WTDT is based on the load assumptions and considered as the most significant parameter for ...

Vibration Sideband Modulations and Harmonics Separation of a Planetary Helicopter Gearbox with Two Different Configurations

open access: yesAdvances in Acoustics and Vibration, Volume 2016, Issue 1, 2016., 2016
This paper examines the spectrum and cepstrum content of vibration signals taken from a helicopter gearbox with two different configurations (3 and 4 planets). It presents a signal processing algorithm to separate synchronous and nonsynchronous components for complete shafts’ harmonic extraction and removal.

Power Flows and Efficiency of Output Compound e‐CVT

open access: yesInternational Journal of Vehicular Technology, Volume 2015, Issue 1, 2015., 2015
Hybridization is the most promising vehicular technology to get significant improvements of the vehicle efficiency and performance in the short‐term. Mechanical transmissions for hybrid vehicles are very often multiple modes transmission, which permit improving the performance in different working conditions. In this context, optimal design and control

Load‐Sharing Characteristics of Power‐Split Transmission System Based on Deformation Compatibility and Loaded Tooth Contact Analysis

open access: yesInternational Journal of Aerospace Engineering, Volume 2015, Issue 1, 2015., 2015
In order to implement the uniform load distribution of the power‐split transmission system, a pseudostatic model is built. Based on the loaded tooth contact analysis (LTCA) technique, the actual meshing process of each gear pair is simulated and the fitting curve of time‐varying mesh stiffness is obtained.

On the Embedded Kinematic Fractionation of Epicyclic Gear Trains [PDF]

open access: yesJournal of Mechanical Design, 1998
In this paper, the concept of kinematic fractionation is introduced for epicyclic gear trains (EGTs) which contains structural fractionation as a degenerate case. With the concept of kinematic fractionation, kinematically independent group(s) embedded in an EGT can be identified.
