Welcome back to the Multibody Dynamics using SolidWorks blog series! In this blog, we’ll walk through the complete process of modeling and assembling the components of an engine valve system in SolidWorks. This guide covers the creation of each part—cam, push rod, rocker arm, valve, and valve mount—followed by assembling them into a complete mechanism. After the modeling, we will proceed to the multibody dynamics simulation. This method offers a clear, detailed approach for students and engineers learning Multibody Dynamics (MBD) using SolidWorks.
Step 1: Modeling the Cam
The cam is the first part we will create. Start by opening a new part file and setting the unit system to millimeters (mm). Here’s how to model the cam:
1. Sketching the Cam Profile:
2. Extruding the Cam:
Step 2: Creating the Push Rod
The push rod, also known as the cam follower, is the second part to model. Follow these steps:
Sketching the Push Rod:
Revolving the Push Rod:
Step 3: Designing the Rocker Arm
The rocker arm transfers motion from the push rod to the valve. Here’s how to design it:
1. Sketching the Rocker Arm Profile:
2. Adding Tangency and Constraints:
3. Extruding the Rocker Arm:
Step 4: Modeling the Valve
The valve is a critical component in the engine valve system. Follow these steps:
1. Creating the Valve Sketch:
2. Revolving the Valve:
Step 5: Creating the Valve Stem
The valve stem acts as a guide for the valve. Follow these steps:
1. Sketching the Valve Stem:
2. Revolve the Valve Stem:
Step 6: Assembling the Engine Valve System
With all components ready, it’s time to assemble them in SolidWorks Assembly:
1. Aligning the Parts:
2. Setting Mates and Constraints:
Step 7: Preparing for Motion Analysis
Now that the assembly is complete, you can proceed with setting up the multibody dynamics simulation in SolidWorks.
Enabling Physical Dynamics:
Conclusion
By following these steps, we’ve modeled and assembled the essential components of an engine valve system using SolidWorks. This approach to learning Multibody Dynamics using SolidWorks not only familiarizes you with the software’s modeling tools but also sets the foundation for more complex simulations in mechanical systems.
In the next blog, we’ll cover the motion analysis in greater detail, providing a complete look at how the engine valve system operates dynamically in SolidWorks Multibody Dynamics.
