829 – ANSYS .

You are required to prepare and submit the ANSYS Mechanical APDL R1 2026 simulation files only for the Connecting Rod project.

The report and presentation are already completed. Your task is to deliver fully functional ANSYS simulation files, organized into three separate sections corresponding to the required analyses.

—

### 1. General Requirements

– Use ANSYS Mechanical APDL R1 2026 only.

– The geometry must match the final model used in the report:

– Length: 150 mm

– Big end diameter: 50 mm

– Small end diameter: 14 mm

– Thickness: 14 mm

– Use Structural Steel (AISI 1045):

– E = 200,000 MPa

– = 0.3

– Density = 7.85E-9 tonne/mm

– Units must be consistent: mm, N, MPa, s

—

### 2. File Structure (VERY IMPORTANT)

You must create three separate ANSYS project folders/files:

—

#### (A) Structural Analysis

This file must include:

– Geometry creation (full 3D connecting rod)

– Element type: SOLID186

– Mesh:

– Fine mesh (~1.5 mm element size)

– Local refinement at holes and fillets

– Boundary Conditions:

– Fixed support at big end

– Force = 5000 N applied at small end

– Solution:

– Static analysis (ANTYPE,0)

Output Required:

– Von Mises Stress contour

– Total Deformation plot

Files to include:

– .db

– .inp

– .log

– Screenshots (mesh + results)

—

#### (B) Modal Analysis

This file must include:

– Same geometry and mesh as static analysis

– Same fixed support (big end)

– No applied forces

– Modal setup:

– ANTYPE,2

– MODOPT,LANB,4

Output Required:

– First 4 natural frequencies

– Mode shapes (Mode 1 Mode 4)

Files to include:

– .db

– .inp

– .log

– Screenshots of each mode shape

—

#### (C) Transient Analysis

This file must include:

– Same geometry and mesh

– Same boundary conditions

– Time-dependent load:

F(t) = 5000 sin(2 50 t)

– Analysis settings:

– ANTYPE,4

– Time step = 0.001 s

– Total time = 0.1 s

– Include damping (Rayleigh damping if possible)

Output Required:

– Stress vs Time graph

– Displacement vs Time graph

– Peak stress confirmation (~211 MPa)

Files to include:

– .db

– .inp

– .log

– Graph screenshots

—

### 3. Additional Requirements

– Each analysis must run without errors

– Files must be clearly named:

– Structural_APDL.db

– Modal_APDL.db

– Transient_APDL.db

– Include a screen recording video showing:

– Opening ANSYS

– Running each analysis

– Displaying results

—

### 4. Final Submission

Submit a single compressed folder (.zip) containing:

1. Structural Analysis files

2. Modal Analysis files

3. Transient Analysis files

4. Screenshots

5. Screen recording video

—

Failure to organize the files correctly or missing any analysis will result in mark deduction.

—Note, after the completion of the project on the program, you will change all the screenshots in the Word and the presentation with the screenshots that you used the program with the version you worked .
