Abstract:
A method for determining total damage to at least one rotating component of a drive train in a system, in particular a wind or wave energy system, includes determining over time during operation of the system a variable characterizing a rotational speed of the component and a variable characterizing a torque transmitted by the component. A load collective is determined in a calculator unit from the temporal progression of the variables, and the total damage is determined from a comparison of the determined load collective and a reference load collective.
