Regulations and CFD development part 2

[email protected]
In my previous article on this subject I examined whether the Formula One regulations still make it possible to be creative with simulation methodology. In this article I want look at what those regulations implicitly prohibit, focusing predominantly on thermal applications.  The option to couple solvers is not limited to structural solvers. The new set of technical regulations in Formula One has put greater emphasis on cooling, and in turn on understanding heat transfer. This is an...

Carbon composite exhausts

[email protected]
In the V8 era of Formula One, which ended with the introduction of new turbocharged and ERS-equipped power units in 2014, the level of component optimisation undertaken was, frankly, incredible. With many years of regulatory stability, teams looked to every quarter in order to find performance gains, with the key areas of investigation being aerodynamics and weight reduction. This led to the development of some unique components that used lightweight materials in areas where they had not...

Tyre modelling

[email protected]
Tyre performance has a huge effect on the dynamic behaviour of a Formula One car, or any race vehicle for that matter. In order to fully understand tyre behaviour, all the teams use virtual tyre models to assess the impact of changes to the chassis and aerodynamics on the way a tyre performs. Predicting tyre behaviour is complex though, and teams are constantly looking for the best balance between maximising grip and extending tyre life.  In addition, the 2014 Formula One rubber is...

Challenges of manufacturing Formula One energy recovery systems

[email protected]
Changes in the Formula One regulations and developments in technologies often push manufacturing to its very limits. Not only is manufacturing generally near to, or at the end of, the development process it has to deliver right first time, on time – and, in motorsport, in very little time. The introduction of kinetic energy recovery systems (KERS) in 2009 combined with the current turbo era has certainly introduced new challenges and pushed ‘green’ technology far beyond the...

Dynamics optimisation and construction of Formula One brake pedals

[email protected]
A driver’s ‘feel’ for braking is perhaps one of the most critical aspects of racing. As much as the talk of brake disc/pad materials, it’s also the kinematics of the brake pedal that are crucial to giving drivers what they needs at their foot.  Fundamentally unchanged in its design for decades, the brake pedal is at in essence a simple part, being a pivoting lever with a plate for the driver’s foot and a bearing housing midway up the lever for the bias...
