and then the governing equations of the block dynamic system are deduced on the basis of the virtual work principle, the deformation compatibility condition and the constitutive relations.
随后,基于虚功原理、变形协调条件和本构关系,推导了块体动力系统的控制方程组。
the face-contact model of gears was established according to the deformation compatibility condition and force equilibrium relationship.
面对齿轮接触模型建立根据变形兼容性条件和力的平衡关系。
this situation makes the concept of elementary volume and saint-venant's deformation compatibility condition used in continuum mechanics problematic.
