The aim of the project was to develop an innovative low-cost car suspension test rig. The final horizontal orientation differs from traditional vertical systems to reduce load on the signal input component, reducing the overall cost. A secondary objective of the project was to create an adaptable rig that could be used to represent different automotive suspension settings.

Suspension systems on a vehicle are essential to ensure that a high level of performance and comfort are delivered. Their ongoing development is paramount to the progression of the automotive industry; the testing equipment needs to be improving in the same way as the suspension systems themselves to ensure the technology can continue to advance.

The rig operates in a horizontal orientation, comprising of a main frame to enclose an electromechanical shaker and two masses suspended by leaf springs. The mass of the system can be varied depending on the desired testing conditions, along with the springs and dampers connecting the masses being completely transferrable. The rig is the first of its kind to work adaptively in a horizontal orientation.

The design process involved using CAD to create a final design, as well as software to model the expected response and control systems that were implemented.

The main components of the rig have been manufactured using the EDMC at the University, with manufacturing tasks carried out by the team or by technicians
