低频振动 meaning in English
low frequency vibration
low-frequency vibration
Examples
- However , the normal electromagnetism rate transducer which has the high inherent frequency of that between 5 - 30hz normally can not get the signal below 1 hz , therefore , it can not be used for inspecting same signal , which confines its applications in engineering project
然而,由于普通的电磁式速度传感器,其固有频率较高,一般都在5 - 30hz之间,很难拾取1hz以下的超低频绝对振动信号,因此不能直接用来测量上述超低频振动信号,制约了该类传感器在工程中的应用。 - Secondly , this thesis analyses and tests the dynamics characteristics of the frame . the first inherent frequency has been ascertained by dynamics characteristics tested , analyzed and finite element calculated , strongly supports us to choose the scheme of benfield frame vibration control
其次，文章分析和测试了苯菲尔框架的动力学特性，通过测试分析和有限元计算确定了苯菲尔框架的第一阶固有频率，为苯菲尔框架大幅低频振动的控制方案决策提供了有力的支持。 - In order to solve this problem , this research adopts the electrical self - regulation circuit in series , on the basis of the unchanged of transfer function of electromagnetism rate transducer , extend frequency bandwidth of the transducer , improving its capability . after the self - regulation , the transducer has high passing feature and inferior lower lever cut - off frequency ( below 1 hz )
为了解决普通电磁式速度传感器不能检测超低频振动信号的问题,本研究采用了一种串联式电子补偿电路,在保持电磁式速度传感器的传递函数性质(高通)不变的前提下,拓展了传感器的频宽,改善了传感器的性能。 - Finally , the technique of vibration suppression is discussed . the passive isolation that is simple is adopted for high frequency part and the effort of high frequency suppression is obvious . the bandwidth adaptive that doesn ’ t need new plants is adopted for low frequency part and simulation results indicate that the scheme is valid for the suppression of bit error rate increasing produced by satellite platform vibration
最后对振动的抑制方法进行了研究,对高频振动采用被动隔离方式,该方法操作简单,对高频振动抑制效果显著;对低频振动采用了自适应带宽抑制方式,该方法无需添加新器件,对抑制低频振动带来的误码率增加作用明显,并进行了仿真验证。 - This continuous rule can put the suspension system in the optimal damping state . the skyhook principle can be combined in this control rule , which can further attenuate the vibration of the car - body in lower frequency range , but the acceleration response in higher frequency range tend to be larger
文中还研究了把基于天棚阻尼原理的阻尼控制策略结合到该控制系统中的复合控制方法，前者能使系统始终处于最优或次优阻尼，后者则能进一步衰减低频振动，但也有增大高频响应的趋势。
