Abstract: Two wheel roll friction drive (RFD) is researched. The mechanism of micro-creep is analyzed, the model of stress and strain in friction contact zone is established. A program is designed according to the boundary element method (BEM) and calculation of different cases are carried on. The law of creeprate of RFD is drew. The correction of creeprate is deduced due to surface roughness, installment error, form error and so on.
