This paper presents a parameter assessment method to determine the eigenfrequency of the pile-soil system.
本文提出一种确定桩土系统固有频率的参数估计方法。
Because the suspension with non linear springs has no eigenfrequency, it could avoid the resonance under certain road uneven random excitations.
由于非线性弹簧悬架没有固有频率,因此避免了在外界激励下发生共振的危险。
The plasma oscillation spectrum of electrical discharge channel is analyzed, and the eigenfrequency of metal crystal lattice vibration is discovered in the spectrum.
