Rotordynamic loads are supported only for three-dimensional continuum and cylindrical elements, shell elements, membrane elements, beam elements, and rotary inertia elements. The spinning axis defined as part of the load must be the axis of symmetry for the structure. Therefore, beam elements must be aligned with the symmetry axis. In addition, one of the principal directions of each loaded rotary inertia element must be aligned with the symmetry axis, and the inertia components of the rotary inertia elements must be symmetric about this axis.
[ Rotordynamic负载仅支持三维连续体和圆柱体单元，壳单元，膜单元，梁单元和旋转惯性单元。 定义为负载一部分的旋转轴必须是结构的对称轴。 因此，梁单元必须与对称轴对齐。 另外，每个负载旋转惯性元件的主方向之一必须与对称轴对齐，并且旋转惯性元件的惯性分量必须关于该轴对称 ]
Repeat this data line as often as necessary to define rotordynamic loads for different elements or element sets.
[ 根据需要重复此数据行以定义不同元素或元素集的转子动力载荷 ]
