Solitary waves propagating in a one dimensional charged granular chain has been investigated numerically. Electrically long-range interaction is introduced into such a nonlinear system for the first time. The propagating characteristics of the waves due to physical parameters of materials are studied systematically. It is found that both single solitary wave and multi-solitary wave can be excited...
A precondition for correctly analyzing the stability of a slope and designing its bracing structure is to study and determine the influence of excavation blasting on the properties of weak intercalation in the layered rock slope. On the basis of in-situ stratification-cracking blasting tests, the properties of weak intercalation were investigated using the LS-DYNA3D program. The displacement distribution...
In order to attenuate low frequency vibration induced by metro train and reduce the influence on inhabitants and sensitive equipment nearby the traffic line, it becomes more important to improve the dynamic characteristics and vibration isolation performance of floating slab track system under the low frequency excitation. A detailed derivation of vibration differential equations is given to analyze...
