Analisi FEM su Paradisco per Moto

At LP9Engineering, we believe in merging academic theory with practical applications, and this recent project exemplifies that philosophy. As engineering students, my colleagues Edoardo Scianca, Martino Rovesti, and I decided to put our academic knowledge into practice by conducting a study focused on improving the performance of a motorcycle we use during our free time. This exercise was part of our exam preparation, but it was also driven by our shared passion for engineering and motorsports.

What is FEM and Why Should We Use It?

The Finite Element Method (FEM) is a powerful numerical simulation technique that helps us understand how a component behaves when subjected to forces, vibrations, or other loads. By discretizing a model into a mesh of small elements, FEM allows us to solve mathematical equations that calculate:

• Stress : The internal forces within the material.
• Displacement : The variations in position of the component under load.

Using FEM, we can predict how a component will perform in the real world. This allows us to optimize its design and material selection before moving to the production phase, saving time and resources.

Our Study: Designing a Disc Brake Guard for KTM EXC

For this project, we chose to design and analyze a disc brake guard for a KTM EXC . Our goal was to simulate the worst-case load scenario: a 3000 N force along the X-axis, representing a collision between the motorcycle and an obstacle at the most critical point of the guard. Since this was a preliminary analysis, we didn't need exhaustive detail at this stage.

Simulation Results

The simulation gave us valuable insights:

• The component does not fail under the applied load.
• The maximum displacement recorded was just 0.965 mm .
• Despite being 3D printed using PLA+ , a relatively low-strength material, the design proved capable of withstanding the applied load. Further simulations suggested that using more advanced materials, such as aluminum or high-performance polymers, would further improve its performance.

A Combination of Study and Passion

This project was a fantastic opportunity to apply FEM to a real-world challenge. It allowed us to deepen our understanding of simulation techniques while working on something we are passionate about. By connecting theory with practice, we were able to make our academic experience more tangible and engaging. Engineering, in our view, thrives on experimentation and hands-on learning, and this project has been an exciting step in preparing for future professional challenges.

At LP9Engineering , we're committed to pushing the boundaries of engineering through innovation and practical experimentation. If you're interested in similar projects or have any ideas for collaboration, feel free to reach out!
