Abstract
A Langevin equation is proposed to perform a simulation for the Feynman ratchet model. A stochastic boundary condition is introduced for the role of a pawl in the Feynman ratchet model. The mathematical model can be solved using the Fokker-Planck equation. The solution is compared with the Langevin simulation. A coupled system of the ratchet elements exhibits smooth unidirectional motion when the coupling constant is large.Keywords
