Abstract: The non-linear soil mechanics model based on Mohr-Coulomb
yield criteria is deducted, and impaction effect of non-column wheels of
compacting roller is calculated using MSC/NASTRAN. The comparison
between calculation and experimentation indicates that the calculation
satisfied the engineering precision and it can replace experimentation
to measure the compaction effect. In the meantime, the compact effect of
two kinds of wheel is simlated and several factors are discussed.
