undamped natural frequency meaning in English
欠阻尼自然频率
无阻尼自然频率
无阻尼自然相应
Examples
- In contrast to phase separation ( curve - fitting ) approaches which are largely mathematical , phase resonance testing is a physical technique . when a structure is vibrating in a normal mode , the undamped natural frequency and normal - mode shap of the structure are directly measured . in the classic phase resonance testing , the test data processing is simpler and the results are more accuracy
相对于相位分离法来说,相位共振法是一种比较直观的物理识别方法,在结构做“纯模态”振动时,通过物理测量直接获得模态参数;试验数据处理工作量小,且精度一般比单输入系统高。
