SENSITIVITY OF STRENGTH, RIGID AND DYNAMIC CHARACTERISTICS OF THE CONSOLE ROTOR TO VARIATION OF DESIGN PARAMETERS

The analysis sensitivity of strength, rigid and dynamic characteristics the console rotor to variation design parameters in paper describes speed rotation shaft, material impeller vary. dependences radial axial displacements on angular velocities modulus elasticity are established. For objects type rotary systems with a cantilever arrangement impeller, not one, but set criteria has been introduced into consideration, which should be taken account research this objects. tendencies change first second critical rotational speeds from elasticity, frequencies density also determined. On basis, recommendations have developed for determining part air blower cantilevered impeller. Keywords: blower; speed; natural vibration frequency; system; stress-strain state
