Optimized Design of 8-Figure Null-Flux Coils in EDS Maglev.
The 8-figure null-flux ground coils in EDS (Electro-Dynamic Suspension) including the PLG (combined Propulsion, Levitation and Guidance) system, which can both suspend and propel maglev vehicles simultaneously, have mainly longitudinal and vertical dimensions such as coil pitch and heights of upper and lower coils. In this paper we investigate these dimensions not only to balance the basic performance for levitation, guidance and propulsion, but also to reduce magnetic disturbance of superconducting magnet. By using an optimization program, we induced the relationship between the basic performance and these dimensions. Furthermore, by implementing a modal analysis, we predicted the vibration of superconducting magnet in different pitches, and thereby proposed these dimensions to decrease the vibration.
Electrodynamic Gravity Generator for Artificial Gravity Modules
Weightless environment is causing numerous deleterious effects on human health. It complicates activities and material handling in space. It is necessary to design a kind of artificial gravity generators as life support systems to enable space exploration and colonization. Rotation is in the focus of all artificial-gravity research as generated centripetal acceleration can be substitute for gravity. The aim is to obtain controlled rotation to achieve at least partial levels of artificial gravity. A very effective way to spin objects in space is to use electrodynamic technologies suitable to be optimized and applied in favourable conditions of cold vacuum without gravity. Artificial gravity will provide opportunities for life sciences and advanced technology research. It will enable sustainable exploration and colonization of deep space.
