Abstract
We selected the main parameters for a new layout of a centrifugal installation featuring a linear motor and magnetic suspension. Since existing test benches for simulating linear accelerations have a range of disadvantages, we propose to consider an alternative to the classical layout, in particular, to reject the rotary link and replace it by a ring-like path structure with a linear motor, along which a trolley carrying the object under investigation will move on a magnetic suspension. We analysed various spatial stabilisation systems for the trolley moving at high velocities. We defined the key initial data, taking into account descent into planetary atmospheres, design specifics of products subjected to G-forces and existing centrifugal installations. We computed the parameters of a magnetic suspension based on high-temperature superconducting yttrium ceramics and electrical engineering parameters of the linear motor, and carried out strength calculations for the movable part of the test bench using the Femap with NX Nastran software package, accounting for the operational loads intended. The paper presents an option for implementing a new structural layout of an experimental installation that ensures linear acceleration testing in various operation modes
