main vibration meaning in Chinese
主振动
Examples
- It is very difficult to solve the problem to make several frequency stagger the frequency of the main vibration sources with the experience analysis method
在设计空间受到多种限制下，要使厂房的多阶频率同时与振源频率错开，给经验试算的分析方法带来了很大的困难。 - This frequency range is proximate to main vibration frequency of the traction machine at rated speed , and , according to this , measures against elevator resonance are proposed
并针对该频率区与曳引机主机额定转速主振频率接近的特点，提出了防止电梯发生系统共振的措施。 - Based on vibration theories and the analysis of the model , using main vibration shape and the natural frequency , defined the concept of parameter sensitivity , and got its formula . based on this foundation , defined the concept of the appraisement coefficient of adjustment automobile rigidity parameter , and give the calculation equation
根据振动理论，在模态分析的基础上，通过利用主振型向量的正交性，导出参数灵敏度的概念，推导了参数灵敏度的公式。在此基础上，提出了调整汽车刚度参数的评价系数，并给出了评价系数的计算公式。 - Synthesized signals with different pulse repetition frequencies ( prf ) and main vibration frequencies ( mvf ) were presented to the brown planthopper . the results showed that prf was a sensitive and important signal characteristic in mating choice . the prf and mvf sensitive ranges of male signals were 70 ~ 90hz , 200 ~ 1700hz separately , and of female signals were about 22hz , 100 ~ 300hz separately
雄虫敏感的prf范围在22hz左右，雌虫敏感的paf范围为70 90hz ，这与实际的雌、雄虫求偶鸣声的pm变化范围是一致的；雌、雄虫能对mvf变化范围较大的信号敏感，雄虫敏感的mvf范围为100 300hz ，与雌虫求偶呜声的mvf变化范围是一致的，而雌虫敏感的mvf范围为200 1700hz ，要比实际的雄虫求偶鸣声的mvf变化范围大的多。 - The elastic effect is different from the effect of rigid support , in this paper , a spindle is simplified as one - disc rotor or multi - discs rotor . by the rules of riccati transfer matrix , the varieties of dynamic properties , inherent frequency and main vibration model of the rotor are calculated
主动磁轴承支承是弹性的，将主轴分别简化为单圆盘转子、多圆盘转子等进行研究，应用传递矩阵法计算出在支承刚度变化时的转子动态特性、固有频率和振动主模态等特性的变化。
