This study focuses on the parameter identification problems of pseudo‐linear systems. The main goal is to present recursive least squares (RLS) estimation methods based auxiliary model idea and decomposition technique. First, an model‐based RLS algorithm given as a comparison. Second, improve computation efficiency, decomposition‐based presented. Then for system with missing data, interval‐varying derived estimating parameters. Furthermore, this uses technique reduce computational cost in...
This paper describes a strategy for robotic hand to pick up deformable 3D objects on table. Inspired by human behavior, the employs two rigid fingers first squeeze such an object until it “feels” be liftable. Such “feeling” is provided (virtual) liftability test that repeatedly conducted during squeeze. Passing of then triggers lifting action. Throughout manipulation object’s deformation and its state contact with table are being tracked based events. Deformable modeling uses finite element...
In order to reveal the mechanism of chain disaster caused by collapse high-altitude dangerous rock bodies in open-pit mines and formation debris flows, field survey method was used clarify morphology, range, scale flows. Combined with geological data mining technical conditions, causes flow were studied. The laws evolution patterns revealed. research results showed that (1) collapse-debris is due coupling effect internal poor engineering conditions external factors such as rainfall,...
Abstract Based on the similarity theory, two physical testing models (double-hole tunnel and single-hole tunnel) with a scale of 1:10 were designed manufactured. A series shaking table tests followed by numerical simulations was carried out to obtain dynamic response characteristics shallow-buried tunnels asymmetrical pressure distributions. The similarities differences in laws between double-hole studied. effects types seismic wave (Wenchuan wave, Darui artificial Kobe wave), peaks...
Under the long-term dynamic load influence of trains, shield tunnel structures are damaged. With increase in operating number, cumulative damage gradually increases. When increases to a certain value, lining produces cracks and loses tensile strength, which leads deformation, damage, etc. In serious cases, ceases operation, causing traffic accidents casualties. Based on finite element software ABAQUS, this paper analyses change rule under train explores buried depth damage. The excitation...
In order to study the working mechanisms of pile foundations applied embankment engineering on weak slope foundations, a finite element model foundation reinforced by is established. The influence position and length stability studied, mechanical response are also studied. results show that different positions have great safety factor deformation embankment. varies greatly from one reinforcement location another. maximum vertical 3 m 27 times 7 m. With lengths, horizontal displacement can be...
Although the current ecological engineering technology can reinforce shallow landslides, it cannot deep landslides. A new type of technology-living tree stump slope protection was developed, aiming at deficiency technology. For living stumps with different tap root lengths, mechanical properties and system were analyzed. The model based on finite element method, using Mohr-Coulomb failure criterion to consider plasticity soil. three-dimensional (3D) models lengths simulated by embedded beam...
Water-jet drilling (WJD) is an effective method for stimulating, exploring, and developing oil gas resources. The self-rotatory water-jet bit (SRWJB) a type of potentially efficient applied in WJD. In this study, the three-dimension model SRWJB established, numerical simulation conducted based on sliding mesh combined with RNG turbulence model. was validated using experimental results. To improve performance, effects standoff distance, rotation speed, nozzle layout parameters capability were...
This paper describes a simple strategy for robot hand to grasp and lift deformable 3D object resting on table. Inspired by the human grasping, employs two rigid hemispherical fingers first squeeze until secure grip is achieved under contact friction, then translate vertically upward. During squeeze, test repeatedly conducted determine if maximum hypothetical liftable weight of reaches its real weight. Actual lifting follows when passed. The object's deformation configuration with plane are...
In order to obtain the seismic internal force response laws of a shallow‐bias tunnel with small clear distance, reliability numerical simulation is verified by shaking table model test. The parameter sensitivity studied using MIDAS‐NX finite element software. effects wave peak (0.1 g, 0.2 0.3 0.4 0.5 and 0.6 g), existing slope angle (30°, 45°, 60°, 90°), distance (1.0 D, 1.5 2.0 3.0 D), excitation mode (X direction, Z XY XYZ direction) on law are studied, respectively. results show that (1)...
The rock slopes with tunnels appear widely in the actual project, but there is no executable basis for seismic stability calculation of slope tunnel. According to upper bound theorem plastic limit analysis and pseudostatic method, solution safety factor tunnel was rigorously derived under earthquake loading. This takes into account design parameters tunnel, horizontal vertical loads, physical mechanical mass. Comparing calculated results existing results, validity proposed method verified....
