Control method and system for eliminating beat vibration phenomenon of double-steel-wheel road roller
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.
本发明公开了一种消除双钢轮压路机拍振现象的控制方法及系统，该方法包括：获取前钢轮振动频率和后钢轮振动频率；响应于前钢轮振动频率和后钢轮振动频率皆不为零，则计算两者差值的绝对值，并将该绝对值与预设的目标值进行比较；响应于所述绝对值大于或等于所述目标值，则调节前钢轮振动频率或后钢轮振动频率，直至两者的差值的绝对值小于所述目标值后，停止调节；本方法通过获取两个钢轮振动频率差值的绝对值，并根据该绝对值控制较小振动频率的钢轮的振动频率增大，使两钢轮的振动频率差值维持在合理范围内，控制简单，消除了整机拍振现象。
