Dynamic Behaviour of a Soil Compaction Tamping Machine

A theoretical model was suggested and equations of motion derived. A computer program was developed to solve the resulting system of equations. Agreement between calculated and experimental results is not quite satisfactory. Reasons for discrepancy are discussed and suggestions for further investigation are given.
