振动式压路机的振动形式主要有两大类,一类是竖直式振动,另一类是水平式振动。本文分析了不同振动形式压路机的激振原理、结构特点以及压实过程的不同,给出了竖直压路机激振力和水平压路机激振力偶矩的计算公式以及其随时间的变化规律,此外通过对比试验给出了不同路段情况下两种振动压路机辗压后密实度随辗压次数的变化规律,并通过试验结果分析给出了相应的结论。 Vibratory roller vibration forms are mainly two categories, one is the vertical vibration, and the other is horizontal vibration. This paper analyzes the vibration principle, structural characteristics and compaction process of different vibratory rollers, and gives the formula of the vertical roller excitation force and the exciting moment of the horizontal roller and its variation with time. In addition, The comparison test shows the variation rule of the compactness of the two kinds of vibratory roller after rolling under different road sections, and gives the corresponding conclusions through the analysis of the test results.
