摘要
依据硬盘驱动系统中读写头与盘面的构造,结合现有的楔型和阶跃型气体滑动轴承的特点,提出了一种气体滑动轴承结构,并采用直接模拟Monte Carlo(DSMC)法数值研究了滑动轴承的最小间距、移动速度和系统温度对轴承承载能力的影响.计算结果表明,所设计轴承的承载能力随移动速度的增大而增加,随最小间距的增加和系统温度的升高而减小;轴承的承载能力对轴承最小间距的变化更敏感.
According to the geometry of read/write head and disk of driving-system, a modified configuration of slider gas bearing was presented referred to the cuniform-type and step-type slider gas bearings. The effects of the minimum gas gap, the moving speed and the system temperature on the load capacity of nanoscale slider gas bearing were studied by direct simulation Monte Carlo (DSMC) method. The results indicate that the load capacity increased with the increased moving velocity, and decreased with the increased minimum gas gap and increased system temperature. The load capacity was more sensitive to the minimum gas gap.
