Persistent exposure of humans to whole body vibration can be experienced in our daily work activities. These vibrations can result in motion sickness, discomfort and even severe health effects .This project work aims to study and analyze human vibration transmitted to a tractor driver by carrying out analytical work to measure Whole Body Vibration (WBV) and thus make them aware about the vibration limits within which their health will be safe. A half car model of tractor occupant system subjected to periodic excitation was modelled and its equations of motions were arrived. The model was then solved using Mathematica Systemmodler software and thereby the acceleration versus time plot for each mass is obtained. Also the half car model is modified with full car model considering pitch and roll vibration in addition to vertical vibration and thereby enhancing the accuracy of the result obtained from mathematical model. The optimum values of suspension parameters are to be found out using genetic algorithm technique.
