摘要:

通过对压路机振动频率波动现象及其产生的原因进行分析,得出了振动频率随振动负荷变化的基本规律;通过数学分析,从理论上推导出影响压路机振动频率稳定性的相关因素。通过对某国产全液压单钢轮压路机进行试验,验证了结论的正确性。提出了改善发动机性能、调整液压系统配置等提高振动压路机压实过程中频率稳定性的方法。

Abstract:

By analyzing the phenomenon and causes of the frequency fluctuation, the basic laws were found that the vibration frequency changed with vibration load. And by mathematical analysis, the factors that influenced the frequency stability were derived theoretically. Then correctness of the proposed conclusions was validated by experiments with a hydraulic single drum roller. A series of methods are proposed to improve the frequency stability, such as improving the engine's performance, adjusting the configuration of hydraulic systems.

Key words: vibratory roller, frequency stability, added mass, discharge
