Mechanics principle is the theoretic foundation of animated drawing design, especially, gravity, air resistance, ground friction force and inertia force, elasticity principle are used abroad.
Through ground test, suitable parameters of the structural filter are selected and the coupling between the flight control system and the aircraft elasticity structure is effectively restrained.
通过试验，选择了合适的结构滤波器参数，有效地抑制了飞行控制系统与飞机弹性结构之间的耦合。

It is shown that the change of dynamic modulus of elasticity and modulus of resistance of ground may affect the dynamic property of the tunnel joint.
