Eutectic high-entropy alloys (EHEAs) have combined both and eutectic alloy contributions, with excellent castability high-temperature application potential. Yet, multielement/triple-phase (TEHEA) designs remain puzzling. This work proposed a new strategy based on an infinite solid solution pseudo-ternary model to reveal the puzzle of TEHEAs. The designed triple-phase (TEHEAs) more than seven elements were identified as face-centered cubic (FCC), ordered body-centered (B2), Laves phase...
SUMMARY Pounding between adjacent bridge structures with insufficient separation distance has been identified as one of the primary causes damage in many major earthquakes. It takes place because closing relative movement is larger than structural gap provided structures. This response controlled not only by dynamic properties participating but also characteristics ground excitations. The consequence spatial variation motions studied researchers; however, most these studies were performed...
The scraper conveyor is a crucial component in mining equipment, operating extremely challenging conditions that frequently lead to blocking faults. To investigate the dynamic characteristics of chain drive system under conditions, coupled model was developed using discrete-element method (DEM) and multi-body dynamics (MBD). This integrated fault analysis explore how behaved various forces positions along scraper. From perspective attitude, it observed farther position from center line...
Abstract In this paper, based on the uniaxial compression test of coal samples, Bonding-particle model (BPM) samples was established discrete element method (DEM). The bond parameters virtual are calibrated by combining theoretical calculation, physical and simulation. Plackett-Burman test, climbing response surface were designed with critical load Fd time td crushing specimen as values, optimal obtained, namely, ultimate normal strength coefficient σ 1.55×107 Pa, tangential τ 1×107...
For semi-closed-loop computer numerical control machine tool, the pitch error of screw caused by thermal expansion can deteriorate positioning accuracy ball feed drive system. This study presents different prediction models for system based on mounting condition, where total is separated into geometric and error. The coefficients in model are identified using multiple linear regression method. validated compensation also done X axis a three-axis milling machine. test results show that...
Electromagnetic linear actuators (ELAs) are used to engage gears in an electric automated manual transmission. The structure is simplified due the elimination of intermediate mechanisms. An ELA can provide 1500 N electromagnetic force drive synchronizer Additionally, dynamic characteristics actuator remarkable, improving performance shifting gears. To achieve balanceable and comprehensive gearshift including shift time, friction work, degrees jerk, Pontryagin's minimum principle employed...
Scraper conveyor is the main equipment for underground coal transportation, and its high-efficiency smooth operation of great significance to safety production. This study simulated process transporting bulk by scraper using discrete element method. Transporting efficiency affected chain speed, static frictional coefficient, particle size, laying angle was studied. Then relationship between coefficient chute wear explored. The stress deformation characteristics during transportation were...

The scraper conveyor is the key conveying equipment for fully mechanized coal mining. Wear failure of chute main form conveyor. In this study, discrete element method (DEM) was combined with wear model. mechanism and regularity were explored by tracking changes in position particles during process. After validation simulation, a test different intrinsic parameters designed. one cycle, three‐body about 32.84 times that two‐body wear. research range, increased increase Poisson’s ratio, shear...
Presented in this paper is a high-performance resonant accelerometer with low cross-interference, temperature drift and digital output. The sensor consists of two quartz double-ended tuning forks (DETFs) silicon substrate. A new differential substrate proposed to reduce the cross-interference from undesirable direction significantly. natural frequency DETF theoretically calculated, then axial stress on vibration beams verified through finite element method (FEM) under 100 g acceleration...
