METHOD FOR SIMULATING THE DISTRIBUTION OF BLADES ON A TURBOMACHINE DISC

摘要

The invention proposes a method for simulating the distribution of blades on a turbomachine disc, the method comprising the steps of:⋅providing a plurality of blade configurations, each blade configuration being associated with a blade and comprising at least one measurement of a balancing parameter measured on the associated blade, ⋅ search for and selection of a bladed-disc distribution combining the configurations of blades supplied with positions on the disc, the bladed disc distribution encouraging the attainment of at least one criterion defined according to a predetermined cost function dependent on the balancing parameter measurements, the search and selection being performed by successive iterations, the method being characterized in that a current iteration in the search and selection involves the steps of: ○ generating a plurality of distributions from a reference distribution, said plurality comprising at least one first nearby distribution generated according to a strategy encouraging the attainment of a first predetermined set of criteria of resemblance to the reference distribution and at least one second distribution generated according to another strategy encouraging the attainment of a second predetermined set of criteria of resemblance to the reference distribution, ○ selecting, from the nearby distributions, a nearby distribution that encourages optimization of the cost function as the new reference distribution.
