摘 要

本文主要是进行结构化设计与可视化设计，主要是一种偏向于服务的性质，阐述了悬臂梁实验平台的设计过程、ANSYS模态分析的过程与数据的来源和使用以及WEB的可视化设计。

首先借助建模软件SW进行悬臂梁实验平台的模型设计。其中包括悬臂梁、悬臂梁实验台、接触式激振器、非接触激振器、阻尼器、加速度传感器、力传感器、力锤、磁座等的设计，这些模型的建立为之后对悬臂梁进行模态分析做了基础准备。

然后再借助有限元分析软件ANSYS对悬臂梁在锤击和扫频情况下的模态进行了有限元分析。悬臂梁采用的材料分别为机械工程中常用的结构钢和土木工程中常用混凝土，分析采样的四个点分别为加速度传感器布置的四个位置，悬臂梁模态的分析的步骤主要是导入悬臂梁模型、设置材料种类、划分网格、添加约束、添加受力、添加分析设置（仿真时常、仿真步数）、分析求解、导出结果，导出的结果为excel表格形式。

最后通过WEB来实现悬臂梁数据的可视化展示。实现悬臂梁数据可视化展示的过程是首先通过HTML里的程序把excel表格里面的数据导入到变量workbook中去，再通过程序读取workbook里面每一个sheet里面的数据储存到worksheet中并变成程序好解析的CSV文件格式，中间通过调用echarts库来生成静态的波形图，再通过setinterval函数来添加一个定时器去不断刷新数据从而实现波形图的动态展示，最后再把CSV文件格式转换成excel表格的形式进行展示。实现这些功能还离不开echarts、jQuery、xlsx.core.min这三个库，故在编程之前首先要导入这几个库。

本文的特点是通过三种软件（Solidworks、ANSYS、Pycharm)的交互使用来实现悬臂梁模态分析数据的可视化展示。

Abstract

This paper mainly focuses on structural design and visual design, which is a kind of service oriented nature. It describes the design process of cantilever experimental platform, the process of ANSYS modal analysis, the source and use of data, and the visual design of web.

Firstly, the model of the cantilever beam experiment platform is designed with the help of SW. It includes the design of cantilever beam, cantilever beam experiment platform, contact exciter, non-contact exciter, damper, acceleration sensor, force sensor, force hammer, magnetic base, etc. the establishment of these models makes the basic preparation for the modal analysis of cantilever beam later.

Then the finite element analysis software ANSYS is used to analyze the mode of the cantilever beam in the case of hammering and sweeping frequency. The cantilever beam is made of structural steel commonly used in mechanical engineering and concrete commonly used in civil engineering. The four points of analysis and sampling are the four positions of acceleration sensor layout. The steps of cantilever beam modal analysis are mainly to import the cantilever beam model, set the material types, divide the grid, add constraints, add forces, add analysis settings (simulation often, simulation often, simulation True steps), analysis and solution, export results, export results in Excel form.

Finally, through web to realize the visual display of cantilever beam data. The process of realizing the visual display of cantilever beam data is to first import the data in Excel table into variable workbook through the program in HTML, then read the data in each sheet in workbook through the program, store it in the worksheet and turn it into a CSV file format that can be easily parsed by the program, in the middle, generate static waveform through calling echarts library, and then use setinterval function Add a timer to refresh the data continuously to realize the dynamic display of the oscillogram. Finally, convert the CSV file format to excel form for display. The implementation of these functions is inseparable from echarts, jQuery xlsx.core.min These three libraries must be imported before programming.

The feature of this paper is to realize the visual display of the cantilever beam modal analysis data through the interactive use of three kinds of software (SolidWorks, ANSYS, pycham).

Key words: cantilever; mode; finite element analysis; visualization
