Closure Scheme Analysis of 3 × 70 m Bearingless Integral Rigid Frame Bridge of Fuzhou Xiamen High‐Speed Railway

open access: yesAdvances in Civil Engineering, Volume 2023, Issue 1, 2023., 2023
The hydrodynamic problems associated with the construction of the sea‐crossing bridge were proposed. The deep‐water approach bridge on both sides of the main bridge of Fuzhou Xiamen high‐speed railway adopts the bearingless prestressed concrete integral rigid frame bridge for the first time in the domestic railway bridge design.

Qualification of a Single‐Use Disk Stack Separator for Cell Separation in Mammalian Cell‐Based Antibody Production

open access: yesChemie Ingenieur Technik, Volume 94, Issue 12, Page 1936-1943, December 2022., 2022
The cell separation process is one of the key elements in biopharmaceutical productions. In the last years, some new devices were launched by different manufacturers. In this work, the novel single‐use disk stack separator kytero 500 from GEA was successfully used for the separation of antibody producing Chinese hamster ovary cells. Abstract Single‐use

Super‐spiral sliding mode controller design for single‐winding bearingless switched reluctance motor

open access: yesIET Electric Power Applications, Volume 16, Issue 12, Page 1492-1501, December 2022., 2022
Abstract The strong coupling effect between the torque system and the suspension system of the single‐winding bearingless switched reluctance motor (SWBSRM) would result in continuous interference to the system and bring difficulties to the design of the control system.

Mathematical modelling and control of bearingless brushless direct current machine with motor and generator double modes for flywheel battery

open access: yesIET Power Electronics, Volume 15, Issue 13, Page 1249-1263, 14 October 2022., 2022
Abstract The performance of flywheel battery is affected by the vibration and friction of traditional mechanical bearing. A novel kind of bearingless brushless direct current machine (BBLDCM) with the hybrid capabilities of electrical machine and suspension is suitable for flywheel battery which reduces the losses and improves the power quality.

Control mechanism of unbalanced magnetic pull in doubly fed induction generator using extra pole‐specific stator windings

open access: yesIET Electric Power Applications, Volume 16, Issue 8, Page 912-925, August 2022., 2022
Abstract The doubly fed induction generator is commonly used in commercial wind turbines because of its simplicity and robustness; it is a wound rotor induction machine. It has a relatively small airgap which makes it more vulnerable to unbalanced magnetic pull.

Mathematical model of a novel 12/14 conical bearingless switched reluctance motor

open access: yesEnergy Reports, 2022
Aiming at the defect that the traditional bearingless switched reluctance motor cannot control the axial suspension force, so that the rotor cannot achieve five-degree-of-freedom suspension by itself, this study presents an innovative 12/14 conical ...

Design and analysis of double 6/3 transverse flux bearingless switched reluctance motor

open access: yesElectronics Letters, Volume 58, Issue 15, Page 573-575, July 2022., 2022
Abstract A novel dual 6/3 Transverse Flux Bearingless Switched Reluctance Motor is proposed to solve the coupling problem between torque and suspension of conventional Switched Reluctance Motor. The working principle is introduced in detail, the motor is modelled by ANSYS, and the accurate mathematical model of the suspension force is deduced and ...
