(2012) 19: 657-663 DOI: 10.1007/s11771-012-1053-y Dynamic response law about gravity retaining wall to seismic characteristics and earth fill properties LIN Yu-lian(林于廉)1, 2, LIU... Press and Springer-Verlag Berlin Heidelberg 2012 Abstract: In order to find the dynamic response laws of retaining walls affected by certain earthquake loads, the influence of the seismic wave......
great effect on dynamic fracture behaviour of welded joints. In the present investigation, dynamic response curve and dynamic J-integral of practical undermatched welded joint and whole base and whole... finite element code. Because of the effect of inertia,dynamic load response curve of computed model waves periodically. Dynamic J-integral evaluated by VCE method is path independent. The effect......
Finite difference method for dynamic response analysis of anchorage systemYAN Zhi-xin(言志信)1, 2, DUAN Jian(段建)1, 2, JIANG Ping(江平)1, 2, LIU Zi-zhen(刘子振)1, 2, 3, ZHAO Hong-liang(赵红亮)1, 2, HUANG Wen... difference method has been verified to be feasible by a case study. It is found that under seismic loading, the dynamic response of anchorage system is synchronously fluctuated with the seismic......
Distributed collaborative extremum response surface method for mechanical dynamic assembly reliability analysisFEI Cheng-wei(费成巍), BAI Guang-chen(白广忱) (School of Jet Propulsion, Beihang University, Beijing 100191, China)Abstract:To make the dynamic assembly reliability analysis more effective for complex machinery of multi-object multi-discipline (MOMD), distributed collaborative extremum......
A theoretical analysis of vertical dynamic response of large-diameter pipe piles in layered soilDING Xuan-ming(丁选明)1, 2, ZHENG Chang-jie(郑长杰)2, LIU Han-long(刘汉龙)1, 2(1. Key Laboratory of Ministry.... Moreover, the effects of the distribution of soil layers are analyzed. The results indicate that the effect of the upper soil layer on dynamic response of the pipe pile is more obvious than......
and the random sample values of dynamic parameters as input quantities, extremum response surface functions were established. A number of random samples were then obtained by using the Monte Carlo method... with high-accuracy for the two-link flexible robot manipulator.
