内平衡 meaning in Chinese

inner equilibrium

Third , the three methods including inertia ! completion , modal cost analysis and inner balanced method are researched respectively and deeply . in the case of the small damping and widely separated natural frequencies , the approximation expression of the modal cost is introduced , and the system is approximately balanced
重点介绍了系统各阶模态价值的封闭表达式和在弱阻尼、频率足够分开的情况下模态价值的近似计算公式；以及在弱阻尼、频率足够分开的情况下系统近似为内平衡，系统的奇异值也可由近似公式计算得到。
At last , according to the typical flexible spacecraft , the relation of the component model and system model is studied . the number of the appendage model is selected through the modal cost analysis and inner balanced method to build the reduction system . the result showed that the reduction system is same with the original system with matlab
利用模态价值分析准则和内平衡降阶准则对所建立的动力学模型进行模型降阶，根据得到的降阶系统的阶数，减小所采用的柔性部件的模态数，从而建立低阶的动力学方程。
