Abstract

A mathematical model of nonstationary rotation modes of the rotor of a centrifugal pump is built with allowance for the displacement of the rotor mass center relative to the rotation axis that causes vibrations in cooling systems of spacecraft. The process of acceleration and ascent of the rotor with subsequently reaching the mode of quasi-stationary oscillations is considered.

对转子不平衡的离心泵的运行进行建模

摘要

建立离心泵转子的非平稳旋转模式的数学模型，并考虑到转子质心相对于旋转轴的位移，该位移导致航天器冷却系统发生振动。考虑了转子的加速和上升过程，随后达到准平稳振荡模式。
