【 摘 要 】

The research on repeated loading and sinkage characteristics of soil can calculate the sinkage of wheel and track in driving process more precisely, so it can help calculate the vibration characteristics and driving resistance of vehicle more accurately. This paper analysis the soil repeated loading and sinkage characteristics based on finite element method. The results shows that the unloading and reloading process of soil can be assumed as a straight line with slope of k on load-sinkage curve, here k is called rebound coefficient. The research conclusion can provide reference to the vehicle terramachanics and other research involved soil deformation.
