Determining the range of allowable axial force for the third-order Beam Constraint Model [PDF]
Mechanical Sciences, 2018 The Beam Constraint Model (BCM) was developed for the purpose of accurately and analytically modeling nonlinear behaviors of a planar beam flexure over an intermediate range of transverse deflections (10 % of the beam length).

Eccentric Rotor Drop Dynamics Study of Vertical Maglev Bearing System
Lubricants, 2023 When considering the problem of a vertical magnetic levitation bearing system, the rotor eccentric fall is more likely to cause the failure of the protective bearing. In this paper, a rotor drop collision model and a protective bearing dynamics model are

Physical Review B, 2019 Quantum fluctuations in vacuum can exert a dissipative force on moving objects, which is known as Casimir friction. Especially, a rotating particle in the vacuum will eventually slow down due to the dissipative Casimir friction. Here, we identify a dissipationless force by examining a rotating particle near a bi-isotropic media that generally breaks ...

Forced axial segregation in axially inhomogeneous rotating systems
Physical Review E, 2015 Controlling segregation is both a practical and a theoretical challenge. Using a novel drum design comprising concave and convex geometry, we explore, through the application of both discrete particle simulations and positron emission particle tracking, a means by which radial size segregation may be used to drive axial segregation, resulting in an ...

Optimization design for reducing the axial force of a vaned mixed-flow pump
Engineering Applications of Computational Fluid Mechanics, 2020 Vaned mixed-flow pump is widely used for liquid transportation in industry and agriculture. The structural-asymmetricity induces large axial force which causes axial vibration and shaft system damage.
