In this paper, load identification is studied in the time domain by combining the coupling method and the precise time integration method. 该文通过耦合方法与精细时程积分法的结合，对载荷辨识问题进行时域分析和推导。
A tooth contact analysis model with a rotating freedom was developed by coupling freedom method to determine the stress and strain field of gears. 摘要利用自由度耦合方法建立了县有旋转自由度的齿轮接触模型，用以分析齿轮的应力应变场。
