Nov.15.2013

Designs and drawings all getting finalized! We are excited to go to FSAE Michigan and North 2014 once again next year!

 

October.19 – 20. 2013

We had an awesome time at the UoT shootout, where we went from cold and dry to the lovely cold and wet! It was amazing once again to meet and see all the teams coming out! Till the next time we meet.

Sorry for the slow updates. We have been busy, preparing, training and testing the new members through the summer. The design cycle never stops, now we just wait for the UoT Shootout!

 





Thank You Princess Auto

18 03 2013
The Ravens Racing Team would like to thank Princess Auto on Ages Drive in Ottawa for donating over $2,000 worth of tools to be used in the Team’s shop and in the newly designed pit cart which will be used at competition this year. A good set of tools are essential to the build of a hybrid race car and with Princess Auto’s generous donation this years team will have the luxury of working with the best quality tools you can find in the Ottawa area. To all the staff and Terry at Princess Auto, we look forward to working with you in the future and representing your brand with a top contending car at the Formula Hybrid Competition this year.

The Ravens Racing Team would like to thank Swagelok for their generous donation of $1500 on January 28, 2013. Swagelok has also agreed to retrofit the RR13 (this years car) with all the necessary plumbing and fitting requirements for the brake system to be used at this years international competition in Loudon, New Hampshire. Kirk and Christian, we look forward to you driving the car at this years sponsor appreciation day!

Flexures: Spherical Bearings Be Warned

7 02 2013

Like most autocross cars, our car uses spherical bearings to attach the a-arms and z-arms to the frame.  A new design currently under development will replace these bearings with flexures, solid components that allow for movement in the vertical direction without moving parts. This design is undergoing physical testing to validate the FEA simulations and to ensure that the car will withstand the forces that occur during a race. Our team is simulating this component using both Pro Engineer and real world MTS testing to analyze the stress distributions and to ensure the component performs to specification.  So far the flexures have performed exactly as predicted by simulation and are slated for implementation on the next iteration of the car.  See the figures below for a selection of the FEA simulations and MTS testing.
