Abstract:
The engine power matching of vibratory tandem rollers is discussed by analyzing the experiment results of tandem vibratory rollers. A type of power matching scheme is proposed by testing the power consumption and variation in one working cycle. The results show that one cycle can be divided into two stages, starting and steady velocity compaction. The power consumption amount is relatively low at the steady velocity compaction stage, which is only a half of the engine rating power. However, the power consumption is large at the starting stage with the instantaneous peak power exceeding the engine rating. The instantaneous large power needs can be lowered by two means, one is by adjusting the peak power time of driving system and vibration system to stagger each other, the other is by resetting the acceleration period and its variation to reduce the pressure impaction in the hydrostatic transmission system. 5 tabs, 3 figs, 12 refs.
