Advantages of using Two-Way Adjustable Damper to Improve Solar Vehicle Suspension Performance
In this paper, two mathematical damper models are analyzed using quarter car model. Analysis is based on the
solar vehicle build by students from Lodz University of Technology. First damper is characterized by symmetry between
compression and rebound action, second one is described by Spencer model and reproduce two-way adjustable hydraulic
device. It provides control over rebound and compression force, hence asymmetric characteristics can be created. The
purpose of this paper is to present the possibilities of improving the vertical dynamics of a solar vehicle by using two-way
adjustable damper. Quarter car models are forced by single excitation imitating road bump. The comparative analysis is
made proving advantage of two-way adjustable damper for solar vehicle. The biggest advantage is significant reduction in
vehicle settling time after hitting the bump.
