摘要: The free-vibration characteristics of shrouded blade packets are studied using the finite-element method. effects various weight ratios, flexural rigidity ratios and length between blades shrouds on frequencies vibration packet investigated.It is shown that a multibladed can be predicted with reasonable accuracy from inference diagram two-bladed packet.The theory developed easily adapted for more complex configurations. results presented compared experimental show good agreement those other investigators.
