nature frequency meaning in Chinese
固有频率
Examples
- The strain type parameters compare favorably with the nature frequency and the displacement parameters on detecting structure damage . 2
在结构损伤识别问题上应变类型的损伤识别指标优于位移、固有频率等类型的损伤识别指标。 - 3 . according to demand of large - scale bridge and civil structure health monitor , a new type of fiber bragg grating accelerometer which has low nature frequency and high sensitivity has been come forth
3 、本文以大型桥梁和建筑结构的健康监测为背景，设计了一种新型的低频高灵敏度光纤光栅加速度传感器。 - Any mechanical system can vibrate under certain conditions . if the frequency of exciting force caused by external drive or self - unbalance is near the nature frequency of the system , a phenomenon named resonance vibration will occur
任何机械系统都会发生振动，当外界激励或自身不平衡引起的激振力的频率与系统的固有频率接近时，就会发生共振。 - The temperature effect which has been calculated is taken as " thermal load " forced on the body , then such thermal stress is settled as general elasticity mechanics question ; secondly , the thermal stress is taken as " surface force " forced on the body , and the new system stiffness is formed which include the extra stiffness matrix , then it changes the nature frequency of the structure
首先，这篇论文介绍温度场和热应力场的有限元方法，建立了三维热传导模型计算有温度场产生的热应力，计算热应力时运用了一种转化思维：将温度处理为“温度载荷” ，这样就能用弹性力学问题的处理方法来求解热应力。其次，将热应力作为结构的“面内力” ，而面内力产生附加的几何刚度矩阵，改变了结构的刚度，影响了结构的固有频率。 - The numerical results show that the nature frequencies of the structure are affected by the temperature effect , boundary conditions and the number or orientations of layers ; the proper orientations can change the nature frequencies ; the effect degree on the nature frequencies of cross - ply laminated cylindrical shell is different from that of the antisymmetric one
结果表明，温度效应、边界约束、铺层层数显著影响结构的固有频率，适当的铺层角度会改变结构的固有频率，不同的铺层方式对结构固有频率影响程度不同。
