Exploring the Dynamics of Motion Along a Path in SOLIDWORKS

In the complex world of mechanical design and simulation, the ability to accurately model the motion of components along a predefined path is invaluable. Kundlik Gadade provides a comprehensive guide on utilising the Path Mate feature in SOLIDWORKS, a powerful tool that offers precision in defining the trajectory of a component's point along a specific path. This feature not only facilitates the simulation of realistic motion but also enhances the design and analysis process of mechanical components and assemblies.

Introduction to Path Mate

Path Mate is a specialised feature within SOLIDWORKS that restricts a selected point on a component to follow a designated path. This path can be defined using various entities such as sketches, edges, or curves. The flexibility of Path Mate allows for the simulation of complex movements, making it an essential tool for designers working with dynamic assemblies, such as robotics.

Implementing Path Mate: A Step-by-Step Guide

Preparation: In this example, a 6-Axis robot, sourced from PartSupply, is prepared with all necessary mates for movement. A vertex is added at the robot's tip to act as the point that will follow the path, which is created using a sketch.

Creating a Path Mate:

  • Step 1: Access the Mate feature from the Assembly tab.

  • Step 2: In the PropertyManager, navigate to the Advanced tab and select Path Mate.

  • Step 3: For Mate Selection, define the component vertex that will attach to the path and select the path itself using contiguous curves, edges, or sketch entities.

  • Step 4: Choose the Free option under Mate Type for Path Constraint, allowing unrestricted movement along the path. Additionally, set Pitch/Yaw and Roll controls to Free.

  • Step 5: Finalise by clicking OK, then test the movement by dragging the component along the path.

Extending Path Mate to Motion Analysis

Path Mate's utility goes beyond simple path following; it can be integrated into Motion Analysis to create a Path Motor, facilitating controlled motion along the path.

Motion Analysis Setup:

  • Step 1: Initiate a Motion Analysis study and select Motor.

  • Step 2: Opt for Path Mate Motor as the Motor Type.

  • Step 3: From the FeatureManager Design Tree, select a Path Mate for Mate/Direction.

  • Step 4: Under Motion, define parameters like displacement, velocity, or acceleration for the motion along the path.

  • Step 5: Confirm with Ok to implement the Path Motor.

Tracing the Path in Motion Analysis

To visualise and analyse the motion along the path, the Trace Path function in Motion Analysis is utilised:

  • Step 1: In the Motion Analysis study, select Results and Plots.

  • Step 2: Choose Displacement/Velocity/Acceleration as the Category and Trace Path for the Subcategory.

  • Step 3: Select a Vertex on the assembly and activate the “Show vector in graphics window” option.

  • Step 4: Execute the Motion Study to witness the designated point's motion along the path.

The Path Mate feature in SOLIDWORKS is a testament to the software's advanced capabilities in simulating realistic component movements within assemblies. By following Kundlik Gadade's detailed guide, users can harness the power of Path Mate for their design projects, from simple path following to complex motion analyses. This tool not only enhances the accuracy of simulations but also opens new possibilities in the design and testing of mechanical systems.
