Model of evaluation of interference between blades shrouds during assembly of turbine impellers

The workability of the product depends on the quality of the assembly process. Special attention should be paid to the interaction of parts during assembly. In joints where the position of the contacting parts relative to each other is decisive, for effective operation of the product, it is necessary to find the force factors that have the greatest impact on the position of neighboring parts. This is so because due to the influence of the force factor, the parts move and interference and gaps are formed in the joints. For this reason, it is necessary to take into account the deformation of the contacting parts caused by the influence of force factors. The study developed an algorithm for calculating assembly parameters taking into account the rigidity of the contacting parts. On the example of the turbine impeller, a model was obtained that allows predicting the position of the blades under the influence of the force factor, taking into account the rigidity of the system.
