Coupling Analysis of Thermal-dynamics Characteristics of High Efficiency and Precision Hybrid Spindle

  • 摘要: 针对采用液体动静压轴承支承的高效精密磨床砂轮主轴工作状况,在砂轮主轴静动态特性分析中,考虑了轴承油膜温升的影响。建立了轴承-油膜流固耦合模型,得到随主轴转速和供油压力的变化而改变的轴承油膜温升和动态轴承支承刚度,然后对主轴系统分别进行静态和动态分析,得到轴承油膜温升影响下的主轴静挠度、动挠度和主轴系统的固有频率。结果表明,对于高效精密磨床,轴承油膜的热特性对砂轮主轴系统的静挠度和动挠度具有显著的影响。
