Variable amplitude control method, device and system for vibratory roller, and vibratory roller
The invention discloses a variable amplitude control method for a vibratory roller. The method comprises the following steps: acquiring data information in the process of increasing the vibration frequency from zero to a preset value of the vibration frequency, wherein the data information is obtained by a road roller in to-be-pressed soil or soil the same as the to-be-pressed soil; obtaining a second-order inherent frequency value of the soil system of the road roller according to the data information; setting the vibration frequency of the road roller, obtaining a vibration frequency set value, and controlling the degree of the vibration frequency set value close to the second-order inherent frequency value; and controlling the road roller to vibrate and grind the soil to be pressed at the vibration frequency corresponding to the vibration frequency set value. A special vibration exciter structure or amplitude modulation oil cylinder or vibration wheel structure in the vibration wheel does not need to be adopted, the amplitude can be changed only by changing the vibration frequency, and the control method is simple and high in reliability.
本发明公开了一种振动压路机变振幅控制方法，包括如下步骤，获取振动频率由零升至振动频率预设值过程中的数据信息；数据信息为压路机在待压土壤或与待压土壤相同的土壤中获取的；根据所述数据信息获取压路机‑土壤系统的二阶固有频率值；设置压路机振动频率，获取振动频率设置值，控制振动频率设置值靠近二阶固有频率值的程度；控制压路机以振动频率设置值对应的振动频率对待压土壤进行振动碾压；本发明无需采用特殊的振动轮内激振器结构或调幅油缸或振动轮结构，仅通过改变振动频率即可改变振幅，该控制方法简单、可靠性高。
