The main goal of the project was to improve methods of vehicle drivers protection against whole-body vibration, that are urgently required to assist vehicle manufacturers and operators in complying with European Directive 2002/44/EC. This directive limits the maximum daily permitted vibration exposure and came into force of law for all EU member states by July 2005.
Some of the most important contributions of the Institute related to vibration analysis and active suspension systems include:
- determination of the influence of passenger's mass and posture on response to random vibration
- theoretical investigation of a linear planar model of a passenger car with seated people
- dry-friction modelling in simple, kinematically excited vibration isolation systems
- vibration mitigation by intelligent control of seat suspension damper
- determination of effects of obstacles on the indicators of road unevenness
- modelling of oscillatory systems with viscous and dry-friction damping under real random kinematical excitation
- identification and optimisation of a vertical seat suspension system for a railway vehicle
- development of x-direction apparent mass model of human body sitting in vehicle seat.
