根据中推预研核心机转子动力特性的理论分析结果,为其设计了弹性支座和多孔质挤压油膜阻尼器(PSFD).以调整其临界转速并控制振动。将弹性支承和PSFD安装在该核心机上进行试车的结果表明,理论计算与试验结果非常一致,临界转速调整到了预期值,阻尼器的减振效果显著。 According to the theoretical analysis of the prestressed core rotor’s dynamic characteristics, a flexible bearing and a porous squeeze film damper (PSFD) are designed to adjust the critical speed and control the vibration. The results of testing the flexible support and PSFD on the core machine show that the theoretical calculation is in good agreement with the experimental results, the critical speed is adjusted to the expected value, and the damping effect of the damper is remarkable.
