摘要： 建立含有物料慢变参数的振动压实系统模型,对该模型采用分段线性化方法与渐近法进行求解与仿真分析.利用YZC-1型振动压路机进行现场试验.仿真结果与试验结果对比表明:所建模型正确,计算结果较准确;在压实过程中下车的固有频率随着物料刚度增大及阻尼的减小而逐渐增大;提高激振频率增大激振力可以提高物料的压实效果,但这样会使系统的振动加剧,引起操作人员的身体不适,因此需要合理的选择激振频率;利用混沌运动可以提高压实效果.

Abstract: A model was developed for a vibrating compactor system with slowly varying parameters of compacted material taken into account. The model was solved asymptotically by piecewise linearization with a numerical simulation done analytically. The YZC-1 vibrating compactor was tested in site and the results were compared with simulation results. It was shown that the model is developed properly and calculation results are basically accurate. In the compacting process the natural frequency of the lower part of compactor increases with increasing stiffness of the material to be compacted and increases gradually with decreasing damping. It is necessary to choose rationally the excitation frequency, since increasing the excitation frequency will cause shake that makes operators very uncomfortable though it can increase the exciting force to improve the compacting effect on road material. In addition, the chaotic motion is also able to improve compacting effect.
