| 摘 要： | 为验证双向顺序耦合法求解的可信性,设计并建立一套气流激振下叶片结构的动力响应试验系统.通过平板叶片振动响应的计算与试验对比分析,验证双向顺序耦合法适用于非共振状态以及共振状态的动力响应求解,数值仿真结果可以准确地反映振动响应的时域变化规律和频域特征.计算求得的振动位移和振动应力具有较好的计算精度,相对误差在40%以内,...

| Abstract: | An experimental system was erected to verify the precision of bidirectional sequential method of solving dynamical responses of blades caused by aerodynamic loads.The following results were obtained by comparison of calculation and experiment.Bidirectional sequential method is suitable for solving dynamical response of blades both in resonance state and in nonresonant state.The calculation results are correct in illuminating the vibration response both in time domain and in frequency domain.Bidirectional se... |
