Based on MATLAB programming

Ishikawa law and amended elastoplastic mechanical stiffness of each part

meanwhile

considering the input shaft torsional stiffness

torsional rigidity between the pivot arm bearing and crank shaft and planet carrier

RV Reducer equivalent torsion stiffness model is established.Due to the mesh stiffnesshas degeneration between cycloid wheel and pin wheel

equivalent torsional stiffness mathematical model of the RV-40E equivalent torsional is amended and st iffness calculation method and results provide a theoret ical basis for the follow-up to solve the RV drive system dynamics calculation model.
