The role of packaging analysis is mainly reflected in the following aspects:
1.Cost Reduction: Delays and wasted costs caused by repeated trials and sample making due to insufficient packaging design originality can be avoided through packaging** design technology.
2.Improve efficiency: The packaging design can use the efficient computing power and technology of the computer to achieve simulation analysis, thereby saving a lot of experimental testing time and cost, and improving the design efficiency.
3.Optimized design: packaging design can detect and analyze packaging materials, packaging structure, and product packaging, so as to find the problems existing in packaging design and obtain the best packaging plan through optimized design.
4.Ensure transportation safety: Through packaging design, designers can more accurately ensure the bearing capacity and stability of packaging in different logistics links, so as to optimize the packaging design, ensure the safety of products in the transportation process, and save costs and resources.
Overall, packaging analysis helps to improve the rationality and effectiveness of the design, reduce the cost of the product, improve the efficiency, optimize the design scheme, and ensure the safety of the product during transportation.

Ansys Getting Started with Analytics Tutorial Sharing
(At the end of the article, you can get the Tsinghua University version of the document for free).
Learning Xi with questions, although it seems utilitarian, is often a very practical and effective way to learn Xi. For the best Xi, to solve xx engineering problems, it is more appropriate than I want to learn Xi good xx software, because the goal is clearer and clearer. For example, learning to analyze the strength of molded pulp structures is a clearer and more specific goal than learning ANSYS software.
The following is an example of an analysis operation, which is explained in more detail in the document at the end of the article.
Master the basic operation of the software
Software is the basic tool for analysis, therefore, it is necessary to master its basic operation and analysis process, such as software installation, interface layout, model building, meshing, parameter setting, adding contacts, applying loads, solving, result display, etc.
Introduction to the Workbench interface.
Analysis module: including Static Module, Dynamics Module, Fluid Module, etc.
Project Interface: Displays each study you have created. An example is a whole that includes the model, settings, and results.
Attributes: Set the properties of each small module (such as geometry and model) in the study
Other: Unit in the menu bar in the upper left corner can switch the unit system.
Create a new project
1.Create a new project file: file new
2.To create a static analysis study, find "Static Structure" in the "Analysis Module", drag the left mouse button, and a green dotted box will be displayed in the "Project Interface", drag the mouse to the green box to successfully create a static analysis study (as shown in the following figure).
A1 (first row static structure): the type of the study.
A2: Engineering database, used to set the properties of various materials (double-click to enter, in"Window switching"to return to the project interface).
A3: The geometry model to be analyzed (double-click to enter the geometric modeling software interface, right-click to select the external model file).
A4: Finite element analysis interface, used to mesh the model, set parameters, and display results (double-click to enter the mechanical interface).
a5 a7: Start**, Result. (Same as A4 in the mechanical interface, generally don't care).
Model import
Right-click the Geometry module of the study and select Import Geometry Browse....and select the model file you want to analyze.
Double-click the model module in the study to enter the mechanical page (as shown in the following figure).
1.Selection Filter: Used to control the selection of points only, faces only, and volumes only.
2.**Analysis Tree: Displays the various functions that need to be used (e.g., meshing, etc.), and is the most commonly used window.
3.View operations: used to translate, drag, and scale the model. (Shortcut: Middle-click and drag Rotate;.)Hold down the Ctrl key + middle mouse button and drag Pan;Hold down the shift key + middle mouse button and drag to zoom out).
4.Analysis Option Properties: When you click once on any of the analysis options in the Analysis Tree, its properties are displayed here. is a frequently used window.
5.Quick Selection Bar: Displayed here when you click on any of the analysis options in the Analysis Tree, which can also be found by right-clicking on the corresponding analysis option in the Analysis Tree.
Meshing
1.Switch units first: click unit in the menu bar in the upper left corner, change to the corresponding unit according to the model, it is recommended to select the third one: mm, kg, n...
2.Set the mesh size: In the Analysis Tree, left-click meshIn the properties box of the mesh (bottom left), select sizingelement size, default is the default value (that is, the computer automatically controls), click default to enter the grid size 2mm
3.Meshing: In the Analysis Tree, right-click on the mesh and click generate
Set constraints
1.**In the analysis tree, left-click on the static structure, in the insert, you can see various loads and constraints. Among them, the most used are: standard earth gr**ity, pressure, force, and fixed support
2.Click on Fixed Support, and the Analysis Tree will now present Fixed Support, where Geometry represents the fixed object in its property box. First, change the filter to "Face", select one of the faces of the cube, and then click "Apply" to the right of the geometry option ("Apply" is not displayed: click it and it will come out).
Set up the contact
There is no contact relationship between this part, so it does not need to be set.
If the imported model is an assembly that consists of multiple parts, such as packaging pulp molding and products, it should be treated as a multi-part composition with contact relationships set for different drop scenarios. You need to set up contacts on the contact surface with interaction relationship, the specific steps are as follows: **Click connections in the analysis tree (if you are not importing an assembly, this option is generally not available), click contact in the quick selection bar, and select the corresponding contact type.
Add loads
Similar to the Set Constraints step: left-click Static Structure Insert Force;Lower-left property box: Set the applied surface and force magnitude.
Solution and result display
*In the analysis tree: Right-click on Solution Solve
1.**In the analysis tree: Right-click on Solution Insert (select the corresponding item), :d Eformation, Strain, Stress (select the first "Total" or "Equivalent").
2.**In the Analysis Tree: Right-click on Solution Evaluate All Results

**Jobs with high thresholds and high ceilings. There is no shortcut to entry and improvement, and learning more Xi practicing more is the only last word. It is also unrealistic to learn Xi ** and master it immediately in one step. It takes a lot of exploration and experimentation, step by step, from being able to make seemingly reasonable results, and gradually growing to making precise results. If you've missed out on learning Xi at school, there's Xi best time to get in touch with a free tutorial now
