The temperature-induced variation in operating force of flow control valves may result performance degradation or even jam faults fuel metering unit (FMU), which significantly affects the safety aircrafts. In this work, an analytical modeling approach temperature-sensitive operating-force servo valve is proposed to investigate temperature characteristics varying conditions. Considering effects, a new extended model built and friction also derived theoretically based on dynamic clearance...
Modeled nonlinearity, time-varying, dynamic coupling finite element model of scraper conveyor according to its actual working condition in the mining, studied transmission mechanism bulk material power and parameters test methods，constructed shape function circuitry, realized computer automatic modeling, by example carried on digital simulation all such as starting, freely stoppage, abnormal load, chains blocked, difference chain’s pitch chain wheel polygon effect, so on.
To control the tension dynamic behaviors of heavy scraper conveyor self-adjusting system used for chain initial was considered. Hydraulic according to principle designed and theory established. new fuzzy- PID controller limit minimum point some given scope. example simulation proved that increase power loss due higher escaping from sprocket wheel lower can be avoided.
This letter proposes a control parameter extraction (CPE) model for the reconfigurable bandpass filter (RBPF) to achieve fast reconfiguration of center frequency and broadband. The CPE consists an automatic hyperparameter generation (AHG) module multioutput XGBoost (MO-XGB) module. AHG, based on Bayesian optimization, is used generate MO-XGB hyperparameters. Through experiments fabricated circuit, extracted parameters RBPFs in 15 ms with root mean square error (RMSE) 0.0098 0.0129 bandwidth,...
In the design of afflux device for air dryer safety valve, a rational structure can improve gas flow condition and suppress pulsation noise as well. This paper designed an required little installation space, its physical mathematical model were built up then. The simulation internal field is processed with CFD (Computational Fluid Dynamics) software Fluent, which interprets inner structure’s impact on characteristics silencing performance. numerical provides designers reliable approach device.
