Abstract
Considered design features modern centrifuges. Revealed that their rotors have moving parts that rotate around a horizontal axis. The dynamics of said moving elements. Using Lagrange equation of the second kind derived differential equations of motion. The simulation visualization of motion using the software package RecurDyn. The research results obtained with the package RecurDyn and analytically showed that their movement can not be sustained, in the positions that are optimal in terms of process. The resulting differential equations can not be prointehrovani elementary functions, so direct traffic analysis difficult. Due to the foregoing stability conditions investigated linear movement approach. Necessary conditions for stability of motion required of the design.
How Multibody Dynamics Simulation Technology is Used
A dynamic model of a modern centrifuge with moving parts that rotate around a horizontal axis. The goal of this design was to have a high centrifugal force while maintaining motion stability. RecurDyn simulations showed that the motion was unstable in positions that were optimal for the technological process. The results showed that the design needs to be adjusted to provide additional stability.
