FIELD: information technology.
SUBSTANCE: vibration characteristics of a component are determined and boundary conditions are applied based on power load and temperature acting on the component during operation thereof. Finite-element models with a different number of finite elements are constructed and modal analysis thereof is carried out. On a selected finite-element model, observation nodes and excitation nodes are selected; concentrated forces are applied to the excitation nodes; displacement of the observation nodes under the action of the applied forces is determined and static compliance values in the observation nodes are determined by modal analysis; static compliance values of the structure are then determined via static analysis in the same observation nodes as during modal analysis; the static compliance values obtained by modal and static analyses are compared; observation nodes where the obtained static compliance values are different are determined; the finite-element model is compared with the component; regions on the component which correspond to location of said nodes are determined and the vibration characteristics of the component are adjusted by changing the shape of the component in regions containing said observation nodes.
EFFECT: adjusting vibration characteristics of a component by changing the shape of a specific area on the component in order to ensure its vibration strength.
