Prerequisites

This project requires the use of Solidworks. Do not select this project if you dreaded the Solidworks sessions in IA.

Aims

The aims of the course are to:

  • To introduce the requirements and constraints associated with the design of an automotive suspension assembly.
  • To perform relevant design calculations to predict and optimise the performance of particular components of the assembly.
  • To understand the importance of selecting appropriate materials, manufacturing processes and standard parts.
  • To perform the embodiment design of a sub-assembly of an automotive suspension.
  • To prepare detail design information necessary for manufacture.

Content

This project involves the design of components of an automotive suspension assembly for a Formula Student race car. Tasks include conceptual, embodiment and detail design, all performed individually. The project should appeal to students interested in mechanical design and automotive engineering.

FORMAT

Lectures will be given on automotive suspension systems and mechanical design. Demonstrators will be available at other timetabled sessions to discuss individual design work. Students work individually, but discussion of ideas will be encouraged. Work takes place in the Dyson Centre in week 1, and in the DPO during weeks 2-4. Solidworks will be used extensively in the second half of the project. Detailed instruction on the use of Solidworks will not be given. You may wish to revisit the IA CAD tutorials and tasks if you have not used Solidworks since IA.

ACTIVITIES

Week 1: Review existing design solutions. Identify the key design requirements and constraints. Estimate the stresses in a suspension assembly. Perform a material selection exercise for several components of a suspension assembly. Write a short report.

Week 2: Select a design concept. Perform calculations to estimate the forces in the suspension assembly. Select standard parts. Write a short report.

Week 3: Design component geometries, select materials and manufacturing processes. Optimise the design to satisfy the requirements and constraints. Prepare a CAD model, a 2D design arrangement drawing, and a parts list.

Week 4: Prepare a dimensioned and toleranced detail drawing of one component of the assembly. Write final report.
