MATHEMATICAL MODELING OF RESOURCE CHARACTERISTICS OF TURBOMACHINES USING NUMERICAL METHODS AND COMPLEX OF PROGRAMMS
Improving the reliability of rotating parts requires the creation of compressors and turbines turbomachines with bladed disks with increased fatigue strength. To ensure data options require mathematical modeling of resource characteristics of turbomachines using numerical methods and complexes of the programs. Real turbo impellers in their manufacture or exploitation always arises detuning parameter. To date, published many papers on the study of the effect of detuning, but among them there is no data on the analysis of the durability of impellers with frequency disorder parameters. Use of mathematical models, numerical methods and the software allows to provide at a design stage creation of turbomachines of the increased reliability at essential cutting of costs for expensive experiment studies and saving of time.
