ABAQUS 轉子動力學載荷


Data lines to define rotordynamic loads (Abaqus/Standard only): 
用於定義轉子動力載荷的數據線(僅限Abaqus / Standard):

First line:

  • Element number or element set label.   [ 元素編號或元素集標簽 ]

  • Distributed load type label ROTDYNF.   [分布式加載類型標簽ROTDYNF ]

  • Actual magnitude of the load, which can be modified by the use of the *AMPLITUDE option.   [ 負載的實際大小,可以通過使用* AMPLITUDE選項進行修改 ]

  • Coordinate 1 of a point on the axis of rotation.   [ 坐標1在旋轉軸上的一個點 ]

  • Coordinate 2 of a point on the axis of rotation.   [ 坐標2在旋轉軸上的一個點 ]

  • Coordinate 3 of a point on the axis of rotation.   [ 坐標3在旋轉軸上的一個點 ]

  • 1-component of the direction cosine of the axis of rotation.   [ 旋轉軸方向余弦的1分量 ]

  • 2-component of the direction cosine of the axis of rotation.   [ 旋轉軸方向余弦的2分量 ]

  • 3-component of the direction cosine of the axis of rotation.   [ 旋轉軸方向余弦的3分量 ]

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負載僅支持三維連續體和圓柱體單元,殼單元,膜單元,梁單元和旋轉慣性單元。 定義為負載一部分的旋轉軸必須是結構的對稱軸。 因此,梁單元必須與對稱軸對齊。 另外,每個負載旋轉慣性元件的主方向之一必須與對稱軸對齊,並且旋轉慣性元件的慣性分量必須關於該軸對稱 ]

Repeat this data line as often as necessary to define rotordynamic loads for different elements or element sets.

[ 根據需要重復此數據行以定義不同元素或元素集的轉子動力載荷 ]
