Deep dry screening is the key unit in mineral processing. A vibrating flip-flow screen (VFFS) can provide effective solutions for fine-grained minerals, and it has been extensively used many industrial fields. An accurate dynamic model of VFFS considering influence materials significant its analysis process research, but rarely studied detail. In this paper, an improved proposed equations are solved to find reasonable operating condition, experiments carried out verify reasonability under...
A dynamic thermodynamic model for static storage of cryogenic liquid is developed to address the critical challenge pressure buildup, which limits large-scale application energy systems. The influence initial volume fractions and heat fluxes on buildup investigated. An experimental system established validate with a maximum deviation less than 5% 7% lossless holding time. exhibits staged variable evolutionary pattern in relation fraction. findings indicate that an optimal fraction, ranging...
Inductive oil debris sensors have been widely used in the health monitoring of mechanical equipment. Such are important for fault diagnosis, life prediction, and prevention catastrophic failures. In this article, concept that residual voltage caused by asymmetry two incentive coils hinders improvement sensor resolution is theoretically demonstrated first time. order to achieve ultrasensitive detection, a novel two-stage autoasymmetrical compensation circuit (AACC) introduced into triple-coil...
Vibrating flip-flow screens (VFFSs) provide an effective solution for deeply screening moist and fine-grained minerals, accurate dynamic model of VFFSs is critical its analysis optimization, thereby improving the vibration stability symmetry VFFSs. In this paper, uniaxial tension, compression, plane shear stress relaxation experiments were conducted on screen panel samples to illustrate that third-order Ogden generalized Maxwell can accurately describe hyperelasticity viscoelasticity panels....
Double-deck vibrating flip-flow screens have been widely used for the repurposing of decoration waste; however, influence shear spring stiffness on screen’s vibration characteristics is under-researched.

In this paper, a mathematical model double-deck screen proposed based system with three degrees freedom. Based experiments industrial screen, were studied. Within range 25...
High-speed railway systems have begun to be widely deployed. To meet increasingly stringent requirements under harsh running environments, we propose and demonstrate three fiber-Bragg-grating (FBG)-based approaches for the strain measurement axle counting in high-speed systems, including matched gratings, grating uneven distribution, semi-free grating. All are laboratory verified evaluated using train load platform. Pros cons also discussed terms of feasibility cost-effectiveness.
This article proposes a self-temperature compensation method based on an analog multiplier, which reduces the circuit thermal drift by more than order of magnitude. An ac bridge eddy current sensor (ECS) is used as example to analyze in detail, and basic principle expounded. A high-precision ECS prototype manufactured tested. Results show that temperature coefficient decreased from 243 5 ppm/°C with this technique. self-compensation simple, effective, universal. Furthermore, technique has...
Dielectric contents, such as air bubbles and water droplets in the lubricating oil, can severely interfere with performance of inductive debris sensor due to effect coil parasitic capacitance.

This article proposes a synchronous demodulation method based on gated integrator for precision sensors, which shows significant improvement in signal-to-noise ratio (SNR) and resolution. Several traditional methods are introduced, especially the lock-in amplifier detail comparison. Through comprehensive analysis of integrator, it is proven that proposed larger useful signal output with similar noise suppression capability compared so better SNR could be obtained. Circuits two manufactured...
The vibrating flip-flow screen (VFFS) is a high-efficiency device currently used for deep screening of moist fine-grained materials. During VFFS operation, the normal operation affected by fatigue damage to shear springs arranged symmetrically on both sides screen, leading equipment failures and disruption production.
