| 摘 要： | 本文用解析法考察刚性转子在无对中弹簧的SFDB(挤压油膜阻尼器支承)中的不平衡响应。首先建立了轴颈进动的运动微分方程,然后用平均法将其变换成代数方程,最后用数值计算的方法求出其解析解,并就短轴承的各种情况进行了讨论。文章还研究了解的稳定性,找出了有解区、失稳区及无解区。

| Abstract: | This paper investigates the unbalanced response of a rigid rotor in SFDB without a centralising spring, It first establishes the differential equation for the axle-neck's whirling movement, and then transforms it into an algebric equation by means of the averaging method. Analytical solution is obtained by numerical computing method. Various conditions for the short bearings are discussed. This pape ralso studies the steadiness of the solutions and finds out the unsteady area and areas with and without solution. |
