An intrinsic plastic ${\mathrm{Cu}}_{45}{\mathrm{Zr}}_{46}{\mathrm{Al}}_{7}{\mathrm{Ti}}_{2}$ bulk metallic glass (BMG) with high strength and superior compressive strain of up to 32.5% was successfully fabricated by copper mold casting. The attributed a large amount randomly distributed free volume induced Ti minor alloying, which results in extensive shear band formation, branching, interaction self-healing cracks. mechanism plasticity presented here suggests that the creation BMGs...
We established a coarse-grained molecular dynamics (MD) model of polytetrafluoroethylene (PTFE) at elevated temperatures. The nonbonding and bonding interaction parameters among PTFE beads were estimated. Then friction for simulating the Fe-PTFE process was developed on basis estimated parameters. influence temperature coefficient investigated. found that decreases with an increase in 300–500 K. This is good agreement experiments. Moreover, we comprehensively analyzed variations energies;...
Irradiation damage of FeCrCo, AlNiCo, SmCo, and NdFeB permanent magnets was investigated by using γ-ray irradiation. Results magnetic property measurement show that FeCrCo have more demagnetization than AlNiCo SmCo. X-ray diffraction analysis shows irradiation leads to the increase crystal mismatch decrease ordering degree. The investigations positron annihilation spectroscopy technique defects in SmCo after induced are not main source partial demagnetization. resistances these discussed...
A coarse-grained molecular dynamics simulation model was developed in this study to investigate the friction process occurring between Fe and polytetrafluoroethylene (PTFE). We investigated effect of an external load on coefficient Fe–PTFE using simulations experimental methods. The results show that decreases with increasing, which is a good agreement results. high could result larger contact area PTFE layers, severer springback as consequence deformed molecules, faster motion thereby...

Considering the magnetic fields modulating in electromechanical integrated gear (EIMG), electromagnetic coupling stiffnesses vary periodically and expressions are given by finite element method. The parametric vibration model dynamic differential equations founded. of forced responses EIMG system deduced when main resonances combination occur. And then, time frequency figured out. characteristics discussed. results show that dominant frequencies always natural system. relative amplitudes...
This study proposes a new type of magnetic gear, namely, the electromechanical integrated that integrates traditional field-modulated drive, and control. The topology operating principle gear are described in detail this article, constraints parameter design speed ratio presented. Moreover, field distribution is analyzed with finite element method. Subsequently, harmonics electromagnetic torque calculated. static torques on all components exhibited by method test. effects parameters...
To address the issues of long testing periods and small sample sizes while evaluating service life heavy-load self-lubricating liners, we propose a succinct method based on Monte Carlo simulation that is significantly fast requires size. First, support vector regression algorithm was applied to fit degradation trajectories wear depth, first second characteristic parameter vectors depth as well corresponding distribution models were obtained. Next, expansion performed using inverse transform...
The double-stator hybrid-excitation vernier motor (DSHEVM) is a type of low-speed high-torque motor. establishment an accurate mathematical model the DSHEVM, determination magnetic field distribution, and explicit physical relationship between design parameters output torque are keys to multi-objective optimization. This study proposes DSHEVM subdomain obtain precise distributions. considers effects relative permeability permanent magnets, split-pole slots, stator slots on distribution....
