The design of the 3-axial centrifuge

摘要

Acceleration(G), in physics, is the rate of change of velocity of an object. Advanced missiles are capable of generating the axial acceleration(Gx), the tangential acceleration(Gy) and the normal acceleration(Gz) during aerial combat manoeuvres, which has seriously threatened flight reliability. In order to improve the reliability of missiles, it is necessary to carry out acceleration tests on the ground. Testers usually separately simulate the acceleration with the centrifuge, but the complex effect of 3-axial accelerations can not be reflected. This paper introduces a new 3-axial centrifuge, which can effectively and synchronously simulate the 3-axial acceleration. The paper also designs the structure and the synchronization control system of the 3-axial centrifuge. At last, the paper shows the result of the simulation and the result shows that the system is reliable, and it's synchronization among 3 axial accelerations is very high. The analysis can also provide a reference for similar centrifuge designers.
