振动压路机——土壤非线性与线性动力学模型对比

Comparisons of Nonlinear and Linear Dynamic Models of Vibratory Roller-Soil

结合实际压实过程中土体变形关系,建立新的非线性振动压路机模型,并选用给定压路机参数进行仿真试验。最后,根据仿真结果与线性模型仿真结果,得到非线性振动压路机模型的优点。

Combined with the deformation relationship of the soil during the actual compaction process, a new nonlinear vibratory roller model was established, and the parameters of the given roller were selected for simulation test. Finally, based on the simulation results and the linear model simulation results, the advantages of the nonlinear vibratory roller model are obtained.
