Modelling driver-seat vibration
- Supervisors: Dr Paul Gunther
- Area: Ergonomics, Automotive Engineering, Mechanical Engineering
- Abstract: Measurement of seat induced driver vibration is highly unreliable due to subjective and temporary influences. In most laboratory environments, a measured 3D or 6D road excitation signal is applied to a shaker system which accelerates a complete vehicle and the driver response is measured with a single soft pad 3D-accelerometer under the driver’s buttocks. Alternatively, the driver response is measured in field studies on roads or test tracks. Both methods depend on subjects (test persons) that change their dynamic characteristics intra- and inter-day. Comparative studies therefore need to be run in a very small time window. In order to achieve better validity and reliability of the true driver excitation, driver vibration models have been created which simulate driver response to specific conditions of vehicle/seat excitation. Based on existing seat-driver vibration models and further lab studies, this PhD project is to extend the model assumptions for all common driving conditions. The mathematical models should then be remodelled in a standard multi-body system and ANYBODY. The project should indentify if driver-seat vibration can be reliably modelled in ANYBODY and if not, recommendations for further ANYBODY development should be developed.
