Thesis Work: CFD/Thermal simulation for brake performance

Let's create the future together.

At Volvo Cars, we believe that being curious and truly committed to understanding people is the key to future success. We are people who care about other people, working together to create new technologies and innovations for safe, sustainable and convenient mobility. Want to join us?

 

What is in it for you?
This thesis work will be carried out within the Department Driving Dynamics and NVH which is a part of VCC´s Product and Quality organization.

The braking teams within Department Driving Dynamics and NVH are responsible for product development at concept phases with requirement settings and concept work but also support quality issues in production. They work closely with suppliers, laboratory testing and complete vehicle testing. They are responsible for updating CAE methods, update scripts and developed internal toolboxes, perform brake CAE NVH simulation and data analysis.

 

Background
Disc brakes are the most common brake systems used in passenger cars. Disc brakes are essential in the development of a car since they are a safety system used to prevent car accidents, even with the electrification pursued by the automotive industry and the introduction of regenerative brakes, friction brakes still play a crucial role to ensure correct brake performance. A correct thermal analysis of the friction brakes is necessary to:

Evaluate fulfilment of the target requirements;

optimize their design towards performance/weight;

Estimate the effects on the braking performance of changes in vehicle surrounding areas (body, air ducts, wheel, …)

Currently FE models are mainly used in the early phase of the product development to dimension and design the friction brakes. To increase reliability and have a broader evaluation on the complete vehicle influence, VCC is looking towards CFD methods to simulate different demanding load cases relevant for brakes dimensioning.

The thesis will be largely connected to the brake cooling project developed in the recent years at VCC and the standard methods used to dimension the brake system.


Scope

This thesis work will include the following parts:
 

Literature survey of the different CFD approaches towards brake cooling;

Test different methodologies used for simulation of the air flow around and inside the brakes;

Perform complete vehicle CFD simulations of external flow;

Analyse the cooling air flow and cooling/thermal capacity of the simulated designs;

According to the thesis development and facility availability also dyno/vehicle testing could be arranged to validate models;

Final thesis dissertation, creation of a database of models along with its documentation.

The work will be perform in close collaboration with Chalmers VEAS division at the department of Mechanics and Maritime Science

 

Profile
