摘　　要：为了验证闭环控制对振动频率稳定性的影响,对单钢轮振动压路机进行试验并采用AMESim软件进行仿真。仿真结果与试验结果证明了模型的正确性。用闭环控制系统对模型进行改进,改进前后的试验结果表明,闭环控制能够在一定程度上提高压路机振动频率的稳定性。In this article,a test of the single drum roller is done and the AMESim software is used for simulation to verify the effect of the closed-loop control on the frequency stability. The results of the test and simulation show that the model is correct. Then,the model is improved by the closed-loop control. The testing results before and after the improvement show that the closed-up control can to some extent improve the frequency stability of the road roller.

关 键 词：压路机 振动频率稳定性 闭环控制 振动液压系统
