# 3.6.8: 梁的位移 (Beam Displacements) 🔷

![图3.6.8.1：在轴向和横向点荷载下由两个元件组成的梁：](/files/-M9XuUlhIQ-_IPO83eEA)

若用户想了解位移如何随着梁的长度的变化而变化，可使用**“Beam Displacements（梁的位移）”**运算器（请参见图3.6.8.1）。沿轴的位移列表：每个断面和荷载工况的三个平移、旋转分量。**“BeamID”**、**“LCase”**、**“maxL”**和**“NRes”**输入端口的工作方式与**“Section Forces（截面力）”**运算器的输入端口类似（请参阅第[3.6.9](/chinese_1_3_3/3-in-depth-component-reference/3.6-results/3.6.9-beam-forces.md)节）。沿轴的位移列表：每个断面和荷载工况的三个平移、旋转分量。

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://manual-1-3.karamba3d.com/chinese_1_3_3/3-in-depth-component-reference/3.6-results/3.6.8-beam-displacements.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
