Abstract

The invention discloses an excitation force control method of an intelligent steering vibratory roller. The method comprises the following steps: detecting the real-time vibration acceleration of a vibration wheel of the roller; processing a real-time vibration acceleration signal into an actual compaction feedback value; comparing the actual compaction feedback value with a preset compaction density value so as to judge whether the actual compaction feedback value is greater or less than the preset compaction density value or not; if yes, controlling a vibrator of the vibration wheel of the roller to rotate so as to adjust the component force, along the vertical direction, of the excitation force of the vibration wheel and further enable the actual compaction feedback value to be equal to the preset compaction density value. The invention also discloses an excitation force control system, comprising a first control subsystem formed by an acceleration sensor, a data processor and a central controller. The control system and the control method are capable of controlling the excitation force in real time, and enable the excitation force direction to change steplessly within a range of 0-90 degrees, thus steplessly adjusting the component force, along the vertical direction, of the excitation force from zero to maximum.

Description

Technical field [0001] The invention belongs to the technical field of vibratory roller control, and specifically relates to an exciting force control system and a control method of an intelligent direction-adjusting vibratory roller. Background technique [0002] Rotary vibrating roller. The rotary vibratory roller control system controls the vibration frequency of the roller by controlling the displacement of the vibrating hydraulic pump of the roller to realize the change of the exciting force of the roller. Its advantages are: simple structure, easy use, convenient maintenance, and simple electrical control system. The disadvantages are: low compaction efficiency, non-adjustable excitation force or small adjustment range, so real-time monitoring cannot be achieved. [0003] Vertical vibrating roller. The vertical vibratory roller control box system still controls the displacement of the vibratory hydraulic pump of the roller to control the frequency of the roller to realize ...
