Dynamics analysis in the design of turbomachinery using sensitivity coefficients

Solving the optimization problems based on numerical models is an important step in the design of machinery and equipment. Special attention is given to the calculation gradient of the target and limitation functions behavior with the variation of design variables (known as sensitivity). Using the sensitivity function and varying the design variables the designer gets the opportunity to analyze various basic design variants quickly and efficiently without timeconsuming calculations for each of them. This allows speeding up greatly the design process and reducing its time input. In this regard the numerical models development using algorithms of sensitivity calculation for the strength and vibration analysis of structures is an urgent task.
