摘要：

We use the Brownian dynamics with hydrodynamic interactions simulation in order to describe the movement of a elastically coupled dinner Brownian motor in a ratchet potential. The only external forces considered in our system were the load, the random thermal noise and an unbiased thermal fluctuation. For a given set of parameters we observe direct movement against the load force if hydrodynamic interactions were considered. (C) 2009 Elsevier Inc. All rights reserved.
