Embodiment Construction
[0020] In order to enable those skilled in the art to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] First, the vibration control method of the vibratory roller provided in the embodiment of the present application is described, please refer to figure 1 , the method includes:
[0022] S101, acquiring the driving speed of the vibratory road roller in real time.
[0023] S102. Compare the obtained traveling speed with a preset vibration start speed and / or a preset vibration stop speed.
[0024] Before making the comparison, first set a preset vibration start speed value and a preset vibration stop speed value, those skilled in the art can understand that the preset vibration stop speed should be greater than the preset vibration start speed, and the preset start vibration speed can be set to The vibration speed is set to 30% of t...

The application discloses a method and an apparatus for vibration control of a vibration-type road roller. The method for vibration control of the vibration-type road roller comprises: presetting a vibration-starting speed and a vibration-ending speed; comparing a driving speed of the road roller with the vibration-starting speed and / or the vibration-ending speed; and controlling a vibration motor to work, if the driving speed of the road roller is increased gradually to the preset vibration-starting speed or the preset vibration-ending speed, and controlling the vibration motor to stop working, if the driving speed of the road roller is reduced gradually to the preset vibration-starting speed or the preset vibration-ending speed. The method and the apparatus for vibration control of the vibration-type road roller realize the automatic control of the vibration of the road roller, avoid phenomenons of untimely vibration-starting and untimely vibration-ending happening, and improve the compacting effect of the road roller.
Description
technical field [0001] The present application relates to the technical field of vibration control of vibratory road rollers, in particular to a vibration control method and device for vibratory road rollers. Background technique [0002] Road rollers can roll sandy, semi-cohesive and cohesive soils, subgrade stabilized soils and asphalt concrete pavement layers, and are widely used in filling compaction operations of high-grade highways, railways, airport runways, dams, stadiums and other large-scale engineering projects. [0003] Vibratory rollers are not allowed to vibrate on the spot or when the driving speed is too low. Therefore, the traditional vibratory rollers set a vibrating speed. Start to work, that is, start to vibrate. However, due to the strong inertia of the polarization block, the time required to stop the vibration is much longer than the start-up time. If the set vibration start-up speed is too low, the stop time of the polarization block will be too long...
