摘要
讨论变截面扭转带冠叶片整圈振动问题,在Hall工作的基础上,提出当量叶片的方法,从而得到一种可在微机上快速计算变截面扭转整圈带冠叶片振动频率的简便估算方法。
The vibration of an assembly of interlock full-ring shroulded turbine wheel with variable-section twisted blades is analyzed by means of an assumed equivalent-blade method, so that a simple mathematical model compatible with microcomputer may be used in calculating the vibration frequency.
