The dynamic analysis of the whole process of compaction is the theoretical basis for the research of intelligent compaction technology. This paper reconstructs dynamic models for both the compaction process stage and compaction completion stage and analyzes the dynamic response using the perturbation method. Building on this, an orthogonal test is designed to quantitatively assess the impact of roller working parameters on subgrade compaction quality. The paper then establishes a method for selecting roller working parameters under rapid construction conditions. The findings indicate that the initial compaction depth for both stages is 7 mm, with vibration force amplitudes of 0.39 mm during compaction and 0.22 mm at completion. The contributions of roller weight, vibration force amplitude, and vibration frequency to the final subgrade compaction quality are 82.62%, 4.92%, and 12.46%, respectively. To compact the subgrade quickly, the choice of work parameters is recommended to be a roller with low frequency and large weight and amplitude.
