Patent ID: 7828706

Claim:
A method for simulating movement along water comprising: receiving angular velocity and torque data from at least one simulated oar in a rotation about a rotational axis; determining a damping load for a drive assembly, in communication with the at least one simulated oar, from the received angular velocity and torque data, the damping load including non-linear and linear damping components; and relating through a transmission the received torque data to the received angular velocity data by the following equation: T i =( J i +N 2 ·J o )· w iaa +(( b i +N 2 ·( b o +b 1 ))· w i +b nl ·N 3 ·w i 2 wherein T i =input drive torque, J i =input rotational inertia, J o =output rotational inertia, N=transmission multiplying factor or gear factor, W i =input angular velocity, W iaa =input angular acceleration, b i =input drag coefficient, b o =output drag coefficient, b l =output linear damping coefficient, and b nl =output non-linear damping coefficient.
