1. A method for directly determining a theoretical damage of at least one component of a device, the method comprising:
providing load-specific reference data in an evaluation unit;
sensing actual load-specific data by a load sensing system;
transmitting the actual, load-specific data to the evaluation unit, wherein the actual load-specific data includes classified load collectives comprising a dwell time of occurring damage variables at defined load levels, a number of load changes of occurring damage variables, and an event count of occurring damage variables; and
scaling the load-specific reference data to the actual load-specific data for calculating the theoretical damage of the at least one component and determining a remaining service life.
