摘　　要：采用加入接触单元和Ｄｕｎｃａｎ－ｃｈａｎｇ双曲线模型的ＡＤＩＮＡ扩展微机程序，用两步增量法模拟轮脚与土壤相互作用的动态变化过程，对叶片式轮脚与土壤相互作用进行了二维有限元分析。结果表明：用有限元方法模拟轮脚与土壤相互作用的复杂过程。The FEM model of the interaction between soil and lugs in floating driving state was developed. The influence of interface of the interaction between soil and lug was simulated by using contact element which can describe the friction character of the interface. Method determining contact points between soil and 8 nodes isoparametric element was established. Two steps increment method was used to simulate the dynamic procedure of the interaction between soil and lug by using ADINA microcomputer program to which contact element and Duncan chang hyperbolic model are added. Two dimensional FEM analysis about the interaction between vane lug, walking wheel lug and soil was also done. It is showed that the calculating results are consistent with tests.
