'F1 Workshop Example 1 - Structural analysis of a frontwing' simulation project by rszoeke


#1

I created a new simulation project called 'F1 Workshop Example 1 - Structural analysis of a frontwing':

In this project a structural and an eigenfrequency analysis of a front wing is demonstrated.

Description

As one may already know, aerodynamics plays a key role in the performance of a Formula 1 race car. With an increased complexity associated with its functionalities as well as safety, the front wing should be designed carefully, bearing in mind that its vortex and wake have a significant impact on the vibrations produced and the stability of the entire vehicle.
 
An FEA and a vibrational analysis act as an apposite tool to help determine the behaviour of the system in response to the vibrations occurring at the front wing and helps gain an appropriate insight into the structural integrity of the material used for its construction. Using this data, design modifications can be made in an iterative process.
 

Project Goals


 
The current project intends to conduct an FEA and an eigenfrequency analysis of the front wing of an F1 race car in order to optimize the design and structural integrity of the material used. Since the wing is symmetrical, only half is used for meshing and simulation, saving computing time and space. The results can later be extrapolated for the entire wing.
 

Geometry


 
The CAD model is courtesy of the Perrinn Team. The model was uploaded as a STEP file to SimScale.

Meshes


 
An Automatic, Tet-Dominant mesh of the first order is used.

Simulations


 
The air pressure was approximated, applied as surface traction on the front wing and a static stress analysis was executed.
 
Additionally, a frequency analysis of the wing is performed and the eigenfrequencies are plotted.
 

Results and Conclusions


 
The results are shown below.
