Development of Simplified Methods for Levitation Force Distribution in Maglev Vehicles Using Frequency Ratio Tests [PDF]
SensorsMaglev vehicles apply the entire vehicle load uniformly onto bridges through levitation forces. In assessing the dynamic characteristics of the maglev train–bridge coupling system, it is reasonable to simplify the distributed levitation force as a ...

Analysis of High Force Voice Coil Motors for Magnetic Levitation [PDF]
Actuators, 2020 A voice coil motor is a simple and linear electromagnetic actuator. Since it has a non-contact force and very low stiffness, it is widely used for precision positioning devices including magnetic levitation systems. During magnetic levitation, high force

Miniature optical force levitation system [PDF]
Chinese Optics Letters, 2021 Optical levitation technology is a new levitation technology for trapping micro/nano-particles. By taking advantage of the mechanical effect of light, it has the characteristics of non-contact and high sensitivity. However, the traditional optical levitation system is large in volume, complex in adjustment, and greatly affected by the external ...

Increased levitation force in a stable hybrid superconducting magnetic levitation set-up
Engineering Research Express, 2022 Abstract We present results obtained with an original hybrid set-up permitting to increase strongly the levitation force of Superconducting Magnetic Levitating (SML) systems. We compare levitation force measurements carried out with this set-up to measurements carried out with a conventional one.

Short-Range Force Detection Using Optically Cooled Levitated Microspheres [PDF]
Physical Review Letters, 2010 We propose an experiment using optically trapped and cooled dielectric microspheres for the detection of short-range forces. The center-of-mass motion of a microsphere trapped in vacuum can experience extremely low dissipation and quality factors of $10^{12}$, leading to yoctonewton force sensitivity.
