Abstract The disc spring‐based self‐centering energy dissipation (SCED) brace is a high‐capacity resilient structural component, characterized by flag‐shaped hysteresis curve, which can provide both damping and recentering capacity to structure. However, the conventional design method for SCED cannot quantitatively take into account friction effects induced combined springs, greatly limits spring size selection combination mode. To address this issue, effect of springs quantified using an...
The self-centering technical approach is used widely to improve building resiliency. This paper presents a double activation brace (DA-SCB) with two groups of disc springs activated successively. Compared current braces (SCBs), the DA-SCB first under small displacement excitation dissipate energy, and reactivated large excitation, leading higher bearing capacity. Cyclic loading tests were conducted on SCB in order comparatively study their energy dissipation behaviors validate hysteretic...
This paper presents a mathematical model for new semi-active vehicle engine mount utilizing magneto-rheological (MR) fluids in squeeze mode (MR short) and validates the by comparing analysis results with experimental tests. The proposed MR is mainly comprised of frame installation, main rubber, plate bobbin coil winding. When magnetic fields on, effect occurs upper gap between bobbin, dynamic stiffness can be controlled tuning applied currents. Employing Bingham flow properties parallel...
Abstract A large number of over‐track buildings have been designed in metropolis during the recent decades for adapting to rapid urbanization and saving land resources. However, are potentially affected by train‐induced vibration that may cause discomfort or health problem residents, which turn needs be carefully evaluated. In this study, responses a high‐rise building with three different transfer types investigated using recorded three‐dimensional accelerations from in‐situ tests. By...
This paper presents an electromagnetic radiation-based method to qualitatively assess mine-induced stress field at the longwall face. We first analyze correlation between (EM) signals and stress, then measure drilling bits in both strike dip directions 11702 working face of Nuodong Coal Mine, China, which indirectly verifies this method. Results show that there is a positive EM intensity stress. In same coal seam, frequency inversely proportional extended size cracks inside rock, dominant...
Sialon ceramic tool material has become one of the most ideal materials for high-speed cutting superalloy materials. However, studies on geometric structure sialon solid end mill is lacking at present. In this work, mills was designed difficult-to-machine nickel-based The force and heat, flank wear machined surface quality were analyzed to study effect main parameters performance. results showed that experienced severe chipping, which leading cause its failure during cutting. temperature...
The process of building rock failure is often accompanied by stress drop and energy release, which seriously threaten the safety structures. To reveal law release transformation in establish a structural health monitoring index based on energy, relationship between acoustic-electrical (acoustic emission electromagnetic radiation) shale limestone studied this paper. results show that, early stage loading, there almost no dissipated change acoustic-electric signals not obvious. In contrast,...
