Li, Jiaqing / Zhang, Zhifeng / Xu, Huigan / Feng, Zhongxu

The vibration test of the vibratory roller is of significant value before delivery and it is mainly done in outdoor test base at present. This method has low efficiency, poor security and reliability, so this paper proposes a new type of test-bed to regulate the commission test of the vibratory roller. This thesis regards the single-drum vibratory roller as a research object, and completes the overall structural design of the test-bed and theoretical analysis. The dynamic characteristics of vibration isolation system of the test-bed are studied by using theoretical analysis, experimental research and simulation analysis methods. According to the working principle of vibration isolation system of the test-bed, the dynamics model of vibration isolation system is established by using two-stage and inclined vibration isolation technology. The vibration isolation system is studied by using rigid-flexible coupling simulation method. Finally, based on the experimental optimization results of vibration isolation system, the test-bed is developed and its function is verified.
