In this blog post, we’ll explore some master-level Solidworks questions and solutions, demonstrating the depth of knowledge and expertise our team can offer.

Question 1: Designing a Planetary Gear System

Problem Statement: Design a planetary gear system with the following specifications:

• The sun gear has 20 teeth.
• The planet gears have 30 teeth each.
• The ring gear has 80 teeth.
• The center distance between the sun gear and each planet gear is 50 mm.

The task requires creating a 3D model of the entire system and simulating its motion to ensure proper meshing of the gears.

Solution:

Step 1: Creating the Sun Gear

1. Open Solidworks and start a new part.
2. Use the "Gear Generator" tool in the Design Library to create a gear with 20 teeth. Adjust the module and pressure angle to suit the design requirements.
3. Save the sun gear as a separate part.

Step 2: Creating the Planet Gears

1. Follow the same process to create the planet gears, setting the teeth count to 30.
2. Ensure that the module and pressure angle match those of the sun gear.
3. Save the planet gear as a separate part.

Step 3: Creating the Ring Gear

1. Use the "Gear Generator" tool again to create the ring gear with 80 teeth.
2. The internal diameter of the ring gear should accommodate the external diameters of the planet gears.
3. Save the ring gear as a separate part.

Step 4: Assembling the Gears

1. Open a new assembly file.
2. Insert the sun gear into the assembly.
3. Use the "Mate" tool to position the planet gears around the sun gear at equal intervals. Ensure the center distance between the sun gear and each planet gear is 50 mm.
4. Insert the ring gear and use the "Mate" tool to position it correctly around the planet gears.

Step 5: Simulating the Motion

1. Use the "Motion Study" tool to create a motion study.
2. Apply rotary motion to the sun gear.
3. Observe the motion of the planet and ring gears, ensuring there is no collision and the gears mesh properly.
4. Adjust the mates and gear properties as needed to achieve smooth operation.

This step-by-step approach ensures that the planetary gear system is designed accurately and functions as expected. Solidworks' powerful simulation tools are invaluable in verifying the design before physical prototyping.

Question 2: Advanced Surface Modeling of a Complex Aerofoil

Problem Statement: Create an advanced surface model of an aerofoil with the following features:

• A streamlined shape with a leading edge radius of 5 mm and a trailing edge thickness of 2 mm.
• A maximum camber of 10 mm located at 40% of the chord length.
• A chord length of 150 mm.

The model should be optimized for aerodynamic performance, requiring the use of surface modeling tools and techniques.

Solution:

Step 1: Sketching the Aerofoil Profile

1. Start a new part in Solidworks.
2. On the Front Plane, sketch the aerofoil profile using spline tools. Ensure the leading edge has a radius of 5 mm and the trailing edge thickness is 2 mm.
3. Use control points and tangent constraints to achieve the desired camber and chord length.

Step 2: Creating the Surface

1. Use the "Surface Extrude" tool to extrude the aerofoil sketch into a surface model.
2. Ensure the extrusion direction is aligned with the chord length, maintaining a smooth, streamlined shape.

Step 3: Refining the Leading and Trailing Edges

1. Apply the "Fillet" tool to the leading edge to achieve the 5 mm radius.
2. Use the "Thicken" tool on the trailing edge to ensure the 2 mm thickness, adjusting the surface as needed to maintain aerodynamic properties.

Step 4: Adding Camber and Thickness Distribution

1. Use the "Lofted Surface" tool to create additional surfaces that represent the varying thickness and camber along the span of the aerofoil.
2. Adjust control curves and guide lines to match the specified maximum camber of 10 mm at 40% chord length.

Step 5: Surface Optimization

1. Apply the "Boundary Surface" tool to refine the transitions between the leading edge, camber, and trailing edge surfaces.
2. Use the "Freeform" tool to make subtle adjustments to the aerofoil surface, optimizing the aerodynamic performance.

Step 6: Final Verification

1. Use the "Flow Simulation" tool to analyze the aerodynamic properties of the aerofoil.
2. Verify that the lift, drag, and pressure distribution meet the design requirements.
3. Make any necessary adjustments to the surface model to enhance performance further.

This process showcases the advanced capabilities of Solidworks in surface modeling, allowing the creation of complex, optimized shapes essential for aerodynamic applications.
