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.

A method for determining total damage to a gear mechanism of a drive train of a system, comprising:
- determining a first variable characterizing a torque transmitted by the gear mechanism over time during operation of the system;
- determining a second variable characterizing a rotational speed of a component of the gear mechanism over time during operation of the system;
- determining, with a calculator unit, a load collective based upon a first temporal progression of the first variable and a second temporal progression of the second variable;
- and
- determining a total damage to the gear mechanism by comparing the determined load collective with a reference load collective using the calculator unit.
A calculator unit configured to implement a method for determining total damage to a gear mechanism of a drive train of a system, the method including:
- determining a first variable characterizing a torque transmitted by the gear mechanism over time during operation of the system;
- determining a second variable characterizing a rotational speed of a component of the gear mechanism over time during operation of the system;
- determining a load collective based upon a first temporal progression of the first variable and a second temporal progression of the second variable;
- and
- determining a total damage to the gear mechanism by comparing the determined load collective and a reference load collective.
A system, comprising:
- a drive train including a gear mechanism having at least one rotating component;
- a drive input fitted at an input end of the drive train;

- and
- a calculator unit configured to implement a method for determining total damage to at least one rotating component of the gear mechanism of the drive train, the method including:
- determining a first variable characterizing a torque transmitted by the gear mechanism over time during operation of the system;
- determining a second variable characterizing a rotational speed of the component over time during operation of the system;
- determining a load collective based upon a first temporal progression of the first variable and a second temporal progression of the second variable;
- and
- determining a total damage to the gear mechanism by comparing the determined load collective and a reference load collective.
