Embodiment Construction

[0034] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0035] In order to eliminate the vibration phenomenon, the absolute value of the frequency difference between the front and rear steel wheels is used as a reference in the present invention, and a control method and system for adjusting the vibration frequency can be realized by adjusting the hydraulic oil flow rate, so that the vibration frequency difference between the front and rear steel wheels Maintain within the set range to ensure the normal operation of the equipment.

[0036] The purpose of the present invention is to eliminate the beating vibration phenomenon produced when the two steel wheels of the double-drum roller vibrate at the same time, and compare the absolute value of the vibration frequency difference between the front and rear...

Abstract

The invention discloses a control method and system for eliminating the beat vibration phenomenon of a double-steel-wheel road roller. The method comprises the steps: acquiring the vibration frequencyof a front steel wheel and the vibration frequency of a rear steel wheel; in response to the fact that the vibration frequency of the front steel wheel and the vibration frequency of the rear steel wheel are not zero, calculating the absolute value of the difference between the two vibration frequencies, and comparing the absolute value with a preset target value; in response to the fact that theabsolute value is larger than or equal to the target value, adjusting the vibration frequency of the front steel wheel or the vibration frequency of the rear steel wheel until the absolute value of the difference value is smaller than the target value, and stopping adjustment; according to the method, the absolute value of the difference value of the vibration frequencies of the two steel wheelsis obtained, the vibration frequency of the steel wheel with the small vibration frequency is controlled to be increased according to the absolute value, the difference value of the vibration frequencies of the two steel wheels is kept within a reasonable range, control is easy, and the whole machine beat vibration phenomenon is eliminated.

Description

technical field [0001] The invention relates to the technical field of road rollers, in particular to a control method and system for eliminating the beating vibration phenomenon of a double-steel wheel road roller. Background technique [0002] Double-drum vibratory rollers are widely used mechanical equipment for pavement compaction. They can be applied to the compaction of multiple layer materials such as foundations and surface layers. They have a wide range of applications and are favored by users for their high vibration compaction efficiency. [0003] The double-drum vibratory roller has two steel wheels at the front and rear. The steel wheels are equipped with the same eccentric vibration excitation mechanism, and the hydraulic motor drives the vibration excitation mechanism to rotate at high speed to force the steel wheel to generate regular vibration to achieve vibration impact compaction. In order to ensure the uniformity of road surface compaction quality, the de...
