Sammanfattning
When developing suspension subsystems for a vehicle, it is necessary to be able to
prepare the design for proper vehicle directional control and handling. A slight understeer
behaviour is targeted at different driving conditions for a passenger vehicle
and several suspension factors impact this behaviour of the vehicle. This thesis aims
at understanding the effect of various suspension and chassis parameters on vehicle
handling and development of a tool that predicts the vehicle steady state handling
behaviour for a user defined suspension setup.
The tool is developed based on the slip angle definition of understeer and a handling
diagram is generated as a result. The slip angles for the tires are determined by
solving a set of non linear equations that describe the equations of motion. The
tool is validated with experimental data from two different sources. The results of
the tool match with the experimental data which validates the method and the tool
developed.
The user interface for the tool is made simple to use. Various configurations for
the suspension setup can be fed to the tool as an excel sheet and the results can be
obtained by running a MATLAB code in the background.
