Increase the quality of eccentric block, which will cause the eccentricity torque increases caused by the amplitude increases, the amplitude is too large will also cause "over compaction" phenomenon. In order to control the amplitude increase, it is necessary to increase the weight of the steel wheel, but this will cause the steel wheel and the pressure wheel frame weight ratio imbalance, the wheel load is certain, the wheel is heavy, the pressure wheel frame must light, The wheel jumps a large range, in other words, the pressure roller frame can not suppress the wheel, the compaction effect is certainly not good, but also cause the machine vibration, affecting the mechanical life, speed up the driver's fatigue. The greater the excitement of the roller From the above can be seen: exciting force, amplitude, frequency of these parameters are mutually constrained, contradictory. Exciting force at the same time but also to ensure that the frequency, the amplitude is not possible. For the user, the pursuit is really good construction compaction effect, rather than who the greater the excitement of the roller who is better the road roller. �� the greater the better the amplitude Under normal circumstances, the greater the amplitude the greater the depth of compaction. But the amplitude is not the bigger the better. When the amplitude is too large, the same will appear "over compaction" phenomenon, resulting in particle gradation disorders, the basis of loose surface, aggregate crushed. Under normal circumstances, the embankment of the amplitude of the road in the 1.4 ~ 2.0mm, compact sub-base of the amplitude of 0.8 ~ 2.0mm, compacted road surface amplitude of 0.4 ~ 0.8mm is better. concrete chainsaw blade swiss
