Epsilon Optics have been involved in a number of racing projects including F1 and Touring Car championships, primarily in the role of design verification in suspension parts and aerofoils. However, there is a growing trend towards permanent in-car systems to provide live feedback to the driver and race team. The Epsilon Optics compact high units are ideally suited for in-car testing proving live feedback and real-time monitoring of data.

Key Features

High Performance Racing Cars

  • Verification of design loads (particularly dynamic loads which can be difficult to predict)
  • Performance enhancement, providing real-time feedback for optimum set-up and operation within design limits
  • Compact ruggedized interrogator tested to aviation specifications
  • Long term structural health monitoring, mitigation of risk of overload and structural failure during competition


Suspension Testing - The Next Phase



Following the successful lab and track testing of the fibre-optic sensing system installed on the Corvette C7R race car, our work with Pratt & Miller has now moved on to the next phase. This involves detailed monitoring of both front and rear suspension components on an IndyCar
Working closely with the P&M design team, Epsilon Optics conducted a further round of FEA analysis to optimise sensor location and orientation. As before, a large number of sensors were embedded in composite carriers for surface bonding to the suspension components whilst improving the ruggedness of sensors and cabling and minimising disruption to the aerodynamics.
The testing is now underway which will include both track and wind tunnel tests.


Suspension Testing and Design Varification



Epsilon Optics have provided a highspeed interrogator and customised embedded composite sensor solution to Pratt and Miller for design verification of suspension parts on the very successful Corvette C7.R race car. The embedded composite solution provided took the form of a precisely moulded composite carrier containing more than a dozen sensors arranged in close proximity to provide high resolution strain monitoring in an area no bigger than the palm of the hand. The precise moulding and ruggedised cabling solution meant the composite patch provided very good strain transfer and is capable of surviving a test environment. This involved working very closely with the design team to review the FEA analysis and optimise the position and sensitivity of the sensors.
