| 9. | Many international experts have done research in amb - ab , but the air bearing occupying a long axis space . the rotor ' s dynamics performance is depressed . a new type amb - ab was brought forward in this paper , the film air bearing was integration in amb
本文研究了一种新型的磁气混合轴承结构，其特点是将箔片气体轴承集成在磁轴承的气隙里面，不占据轴向空间，因此与国外的研究有本质的区别。 |
| 10. | Because it is impossible to adjust the air bearing absolutely balance , the difference between mass center and rotation center must lead to a notable gravity disturbance torque . in the process of identification , modeling and identification of gravity disturbance torque is considered , and an extended kalman filter is educed for identifying air bearing inertia matrix and gravity disturbance torque , and then the algorithm is validated
由于气浮台平衡调试方法和手段的限制,实验过程中气浮台质心与转动中心有一定的位置偏差,必将导致较大的重力干扰力矩,在辨识算法的推导过程中,重点考虑了重力干扰力矩的建模和参数辨识问题,推导了气浮台的转动惯量和重力干扰力矩辨识的扩展卡尔曼滤波算法,并对算法进行了数学仿真和全物理仿真验证。 |
