General prediction model of residual pretightening force of bolt group with one-step and multi-step pretightening and analysis of influencing factors from the perspective of elastic interaction
Wujiu Pan, Xianmu Li, Lele Sun, Hongxing Song, Minghai WangThe purpose is to predict the distribution of the residual pretightening force of the bolt group under the action of any initial pretightening force, and to achieve the final…
Investigation on the wall thickness variation of an eccentric tube in the rotary draw bending process
Zengkun Zhang, Dongru Li, Jianjun Wu, Muzamil Muhammad, Yang LiWhen bending a large diameter thin-walled tube, the thickn ess of outer side wall will reduce greatly, which leads to a decrease of structural strength of the tube. To solve this…
Simulating dual solutions of coupled pore-fluid flow and chemical dissolution problems in fluid-saturated heterogeneous porous media
Chongbin Zhao, B.E. Hobbs, Alison OrdThe objective of this paper is to establish a solution strategy for obtaining dual solutions, namely trivial (conventional) and nontrivial (unconventional) solutions, of coupled…
A hybrid method to determine optimal design axial forces of servo steel struts in excavations with high deformation requirements
Honggui Di, Yuyin Jin, Shunhua Zhou, Di WuThe application of servo steel struts enables the active control of the excavation-induced deformation in foundation pits. However, there is currently only one design axial force…
Adaptive linear quadratic regulator for optimal structural control based on wavelet transform and genetic algorithm
Haylim Chha, Yongbo PengIn real life, excitations are highly non-stationary in frequency and amplitude, which easily induces resonant vibration to structural responses. Conventional control algorithms in…
