Team Hare Sponsorship- The Suspension Team
metals4U are proud sponsors of Team HARE 2019; a group of extremely talented engineering students from The University of Huddersfield.
This week we asked Team HARE to take some time out of their busy schedules to update us on how the suspension team are getting on with their elements of the design and build project.
Each part of the Formula Student race car build must conform to stringent rules regarding construction, material qualities, and health and safety elements. Team HARE have been working hard to fulfil all the criteria to ensure complete compliance to the IMechE rules as the Silverstone static and dynamic testing dates draw closer.
Team HARE 2019 suspension team consists of 2 members, Danny Mall and Jack Lynas, they had this to say about how their department has been getting on.
"Our largest development for the year has been our move from 13’’ wheels to 10’’ wheels, saving roughly 15kg of unsprung mass. This has required a full redesign of the suspension system, completely starting from scratch. To design this new system an outside-in method was adopted, choosing tyres and wheels then working inwards through the hub and upright, then wishbones and tie-rods.
The tyre data was analysed to find the optimum working area of our chosen tyre. The suspension geometry was designed through a software called Lotus Shark, allowing for optimisation of the kinematics to maximise the tyres performance.
The design of the parts was completed through Solidworks CAD package, allowing a full assembly of the system on the car. This has allowed for full integration with the rest of the car, as well as Finite Element Analysis (FEA) of all components to minimise weight and maximise strength.
All suspension members have been constructed using T800H multi directional weave carbon fibre tubing. This gives a total suspension member weight saving of 5.5kg compared to steel equivalents. 7075-T6 aluminium inserts, utilising PTFE lined spherical bearings, have been bonded to the tubes using 3M 9323 epoxy structural adhesive."
About the team.
Daniel is from Somerset and currently studying towards his MEng in Mechanical Engineering. Daniel has overall responsibility for the design and optimisation of the suspension system. When not busy with Team HARE projects he enjoys wakeboarding, surfing and skateboarding- funnily enough, not sports that include wheels!
Originally from Essex, Jack's role within the suspension team is to design the suspension system for the new 10" wheels. When he is not working hard towards his Automotive and Motorsport Engineering MEng, he likes cycling on both one or two wheeled models, carting, surfing, and like many students- sleeping!
