In this paper, the behavior of coupling between the translation and rotation of the rigidbody with variable boundary is investigated using numerical method via a typical example.
通过一典型的时变边界刚体实例，用数值方法研究时变边界刚体的平动与转动的耦合特性。

The motion of a rigidbody can be divided into two types: translation and rotation, so the kinetic energy ofrigidbody is made up of translational energy and rotational energy.
刚体的运动分为平动和转动，那么刚体的动能也就包括平动动能和转动动能。

An unconstrained rigidbody has six degrees-of-freedom: translation in three coordinates and rotation about three coordinate axes.
