Abstract: Impact Compactor,for whose active wheel’s structure is special,it requires highly for the traction force when working,and it is difficult to suit for the machine in working on today.It has direct effect on the satisfactory realization of the design of product whether the machine for drawing is suitable or not.If there is no suitable machine for drawing,it can block the traction force when the impact compactor is working.So scientific and accurate analysis and calculation on the requirement for traction force is necessary when the impact compactor is wor king.
