Effects of Material Selection on the Remanufacturability of a Swashplate in an Axial Piston Pump

Journal of Advanced Manufacturing and Processing, Volume 7, Issue 3, July 2025.
ABSTRACT A swashplate is a critical component in an axial piston pump for motion transformation that undergoes cyclic loading. Traditionally, swashplates are not designed to have multiple lives of operation. According to industry experts, a remanufacturability analysis of swashplates suggests that the scrap rate is high.

Prediction of Slipper Pressure Distribution and Leakage Behaviour in Axial Piston Pumps Using ANN and MGGP

Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019
The pressure distribution (PD) and leakage between the slipper and swash plate in an axial piston pump (APP) have a considerable impact on the pump efficiency, affecting aspects such as the load bearing and wear performance of the slipper. Herein, multigene genetic programming (MGGP) and artificial neural network (ANN) machine learning methods (MLMs ...

Vibration and Performance Analyses Using Individual Blade Pitch Controls for Lift‐Offset Rotors

International Journal of Aerospace Engineering, Volume 2019, Issue 1, 2019., 2019
This work attempts to reduce the hub vibratory loads of a lift‐offset rotor using IBC (individual blade pitch control) in high‐speed forward flight. As a lift‐offset rotor for the present study, the rigid coaxial rotor of a XH‐59A compound helicopter is considered and CAMRAD II is used to predict the hub vibration and rotor performance.

Active noise control by means of high frequency injection in electric motors

IET Electric Power Applications, Volume 18, Issue 8, Page 897-911, August 2024.
Aiming to improve the acoustics surrounding motor drives, this paper proposes the application of High Frequency Injection (HFI), with the aim of creating acoustic noise that is in anti‐phase relation to an unwanted noise. The injected High Frequency (HF) voltage produces torque pulsations and vibrations within the motor. This vibratory energy initiates

Electrically Controlled Rotor Blade Vortex Interaction Airloads and Noise Analysis Using Viscous Vortex Particle Method

Shock and Vibration, Volume 2019, Issue 1, 2019., 2019
An electrically controlled rotor (ECR), also called a swashplateless rotor, replaces a swashplate with a trailing‐edge flap system to implement primary rotor control. To investigate the aerodynamic characteristics of an ECR in blade‐vortex interaction (BVI) condition, an analysis model based on the viscous vortex particle method, ECR blade pitch ...

Maximizing wind farm power output with the helix approach: Experimental validation and wake analysis using tomographic particle image velocimetry

Wind Energy, Volume 27, Issue 5, Page 463-482, May 2024.
Abstract Wind farm control can play a key role in reducing the negative impact of wakes on wind turbine power production. The helix approach is a recent innovation in the field of wind farm control, which employs individual blade pitch control to induce a helical velocity profile in a wind turbine wake. This forced meandering of the wake has turned out
