对“压路机—土壤系统”动力学方程的再分析

Further analysis of dynamic equations of road roller and soil system

针对文献中关于对“压路机—土壤”系统典型动力学方程给出的解所存在的问题,运用振动理论对其系统的动力学方程进行再分析。在分析求解的过程中引入阻抗矩阵,比较简捷地求出了振动系统的稳态响应,并非常清晰地展示出了文献中“压路机—土壤”系统动力学方程解出现问题的原因,最后对其解进行修正和补充。

s: Some problems in the solutions of the typical dynamic equations for the road roller and soil system given in references are analyzed by using the vibration theory. Impedance matrix is induced in the analysis for the solutions. The reasons for the problems in the solutions are clearly explained. The solutions have been modified in the paper and may be used for reference to the colleagues doing the research on the machinery and technique of vibratory rollers.
