一、引言 空气轴承在整个工作期间(如在机床上)都要受到振动。如果能使轴承气膜力产生的振动阻尼十分合理就可保证轴承在工作载荷作用下稳定持久地工作。因此设计工程师应该掌握轴承的动态特性。 若假定气膜具有线性动态特性,即具有恒定的刚度和阻尼系数,则确定空气轴承的动态特性就很方便,下面介绍的分析法能预测上述系数值。肖然这种假定的正确性需经实验检验。
I. INTRODUCTION Air bearings are subjected to vibration during the whole working period (such as on the machine tool). If you can make the bearing film force generated by the vibration damping is very reasonable to ensure that the bearing under the action of the load stable and lasting work. Therefore, design engineers should master the dynamic characteristics of bearings. If it is assumed that the film has a linear dynamic behavior, that is, a constant stiffness and damping coefficient, it is convenient to determine the dynamic characteristics of the air bearing. The analytical methods described below are predictive of the above coefficient values. Xiao correct assumption of this test to be tested.
