Dec 28, 2017 · 在Workbench界面下,转子谐波响应分析用Rotating Force来考虑不平衡力,用户可以输入不平衡质量或直接输入不平衡力,如下图所示,此处案例为输入不平衡质量,可以通过修改Calculated From来设置为直接输入不平衡力。

May 24, 2023 · A rotating force doesn't have to be defined with the "Rotating Force" in Mechanical. It can just be defined with a complex "Force" as shown below. You can define as many complex forces as you want.

On the Environment Context tab, open the Loads drop-down menu and select Rotating Force. Alternatively, right-click the Environment tree object or within the Geometry window and select Insert > Rotating Force.

Jul 16, 2023 · 不平衡量是通过施加Rotating Force来实现的。 当选择打开 科氏效应 （coriolic effect)时，在分析设置中一般选用solution method:full进行计算分析。 对于基于二维轴对称谐波单元的转子-轴承系统不平衡响应来说，同样使用的是Harmonic Response模块进行的。

Because complex notations are used in a harmonic analysis, a rotating load is defined with both a real component and an imaginary component. For example, to apply a rotating force F0 in the (YZ) plane, rotating in the counterclockwise direction (Y to Z), the force components are:

Mar 10, 2017 · 在Workbench转子动力学谐响应分析中,旋转力是采用实部和虚部定义,Workbench中提供特定的Rotating Force用于载荷定义。 而在瞬态分析中Rotating Force无法被激活,则需要通过表格数据定义各方向、各时间步的力幅值。

本文介绍了对一个安装在简支轴上的圆盘进行力学分析的过程，包括模型设置、静力学分析、模态分析和谐响应分析。 通过添加质点、设置网格尺寸、施加边界条件等步骤，对圆盘进行了详细的分析。 最后，通过后处理得到了频率响应和相位响应等结果，并进行了自定义设置。 文章还强调了学习APDL命令流语言对于深入学习ANSYS的重要性。 质量为5千克的圆盘安装在直径0.01米，长度0.5米的简支轴上。 所有的结构都是圆柱形圆盘的重心距几何中心5 x 10 -3 m。 盘中心的等 …

请问在ANSYS Workbench中做谐响应分析时，如何加载rotating force？总是找不到hit point 的ID。

Feb 26, 2025 · The first point implies that the farther the force is applied from the axis of rotation, the greater the angular acceleration; the second implies that the effectiveness depends on the angle at which the force is applied; the third implies that the magnitude of the force must also be part of the equation.
