This dissertation presents drawings, design thoughts and finite simulation of a structural chassis that can be used
as an entry for formula student.
Three designs based on a layout that suits four hub mounted electric motors have been rendered in Fusion 365
and presented in this assignment. The designs have been given three main goals which were derived from research
into motorsport design practices, those goals are; a)Torsional rigidity b)Weight c) Weight distribution.
Each concept has been measured against these three goals by use of simulation software to find the most suitable design. Where appropriate the software has been validated by calculation. To remove author bias, a student pole was carried out with the automotive engineers at Glyndwr University to give weight to each of the goals. – Weight distribution was given priority.
The winning design. – Concept C is of tabular steel and aluminium and makes use of torsion bar suspension to
achieve a lower centre of gravity than the other concepts. Its torsional rigidity has been improved by use of a bulkhead design that also allows for multiple suspension hard points options.
Along with the three main goals, an enthesis on the chassis environmental impact and how this may help
sponsorship has been considered by using materials that are widely recyclable and having a power supply that could be sustainable.
