摘要
介绍了一种新型压液式在线自动平衡系统,基于Fluent软件,对执行器内部流场进行模拟仿真和性能参数分析,得到相关结论.实验结果表明,平衡液转移过程中,液体黏度 10cSt比黏度 100cSt时响应更快,为后续优化提供方向;转子不平衡振幅从 18.3 μm降低至 10.6 μm,验证了平衡系统的有效性.
Abstract
In this paper,a new hydraulic on-line auto-balancing system was described.Through having Fluent software based to simulate and analyze the flowfield within the actuator,the relevant conclusions were obtained and verified by experiments.The experimental results show that,the response of liquid vis-cosity 10cSt is faster than that of viscosity 100cSt,which provides the direction for later parameter opti-mization.The rotor unbalance amplitude decreased from 18.3 μm to 10.6 μm,verifies effectiveness of the balancing system.
