本文首次推导出了有气穴半油膜和无气穴全油膜的油膜力在固定直角坐标系下的解析表达式,因此我们可以把各种支承上的非对称刚性转子看成多自由度系统,研究它的稳态响应。本文还用非线性的方法,编写了能自动选择合适初值的各种通用程序,并做了精密的实验。实验与计算吻合良好,从而提供了既简便又可靠的设计方法。 In this paper, for the first time, the analytic expression of the oil film force of a gas-filled semi-oil film and a cavitation-free oil film in a fixed rectangular coordinate system is deduced. Therefore, we can regard asymmetric rigid rotors on various supports as a multi-freedom system, Study its steady-state response. In this paper, we also use a non-linear method to write a variety of common programs that can automatically select the appropriate initial value and do a good experiment. Experiments and calculations are in good agreement, providing an easy and reliable design method.
