STUDY ON THE VIBRATION CHARACTERISTICS OF BLADED DISKS (EFFECT OF DAMPING VARIATION ON THE RESONANT RESPONSES OF BLADED DISKS)

Study on the vibration characteristics of bladed disks (Effect of damping variation on the resonant responses of bladed disks)

Although bladed disks are nominally designed to be cyclically symmetric (tuned system), the vibration characteristics of all blades on a disk are slightly different due to the manufacturing tolerance, deviations in the material properties, and wear during operation.These INOSITOL small variations break the cyclic symmetry and split the eigenvalue p

Numerical simulation and validation of ice filling process for ice slurry precooling box packaging of broccoli

[Objective] In order to solve the problem of uniformity of ice crystal distribution in the process of ice slurry filling.[Methods] Taking broccoli as the research object, the physical model of packing broccoli in Wormwood carton was established, and the effects of ice filling speed and ice filling Angle on ice crystal distribution uniformity during
