Fused deposition modeling (FDM) is a rapidly growing 3D printing technology. However, materials are restricted to acrylonitrile butadiene styrene (ABS) or poly (lactic acid) (PLA) in most equipment. Here, we report on new high-performance material, polyether-ether-ketone (PEEK), which could surmount these shortcomings. This paper devoted studying the influence of layer thickness and raster angle mechanical properties 3D-printed PEEK. Samples with three different thicknesses (200, 300 400 μm)...
The integration of adjacent dc microgrids (MGs) results in the formation a MG cluster which can increase system power supply capacity. This article proposes control strategy for clusters combines communication-free and distributed fixed-time to simultaneously achieve current sharing voltage regulation with excellent transient characteristics. Firstly, control, presents greater flexibility than is used layer. Subsequently, layer balance output each MG. optimal parameters are obtained by using...
Automatic emergency braking systems (AEBS) significantly improve the active safety performance of commercial vehicles, but their effectiveness is affected by vehicle’s driving conditions, which mainly include vehicle load and road conditions. In order to adaptability AEBS, an AEBS control strategy with adaptive conditions was proposed validated using a simulation experimentation. This designed based on estimation mass, center gravity position, grade, tire-road friction coefficient....
Abstract This paper introduces a method for calculating the deformation displacement of origami mechanism. The bearing capacity each face can be analyzed by relationship between stress and displacement, which provide reference design. Miura mechanism unit is considered. First, folding angle crease solved based on geometric characteristics. deforming form creases then analyzed, bending moment acting surface solved. Based characteristics forms, modeled as sheet. theory thin plate with small...
This paper investigates into the feasibility of a combined use Ultra-wideband (UWB) and Global Navigation Satellite System (GNSS) / Inertial (INS) for integrated navigation in GNSS challenged environments. The performance original GNSS/INS system deteriorated rapidly due to signal outages. position information provided by UWB is used as observation quantity Extend Kalman Filter (EKF) make up influence loss. Considering positioning service closely related geometric distribution base station...
In recent years, the Kalman filter based on minimum error entropy (MEE) criterion has been proposed, which outperforms traditional in presence of non-Gaussian noise. practical applications, estimated performance MEE unscented (MEE-UKF) algorithm is influenced by kernel bandwidth (KB). addition, it may be unstable numerical computation. This paper proposes an adaptive robust (AMEE-UKF) to address problem instability setting factor optimize MEE-UKF, appropriate value KB can obtained...
Aiming to improve the positioning accuracy of vehicle integrated navigation system (strapdown inertial system/Global Positioning System) when Global System signal is blocked, a mixed prediction method combined with radial basis function neural network, time series analysis, and unscented Kalman filter algorithms proposed. The composed by dual modes network training prediction. When works properly, analysis are trained error between strapdown system. Furthermore, predicted values both applied...
In this article, a prediction method based on radial basis function neural network and an improved unscented Kalman filter, is proposed to improve the accuracy of position velocity Global Positioning System/Strapdown Inertial Navigation System (GPS/SINS) integrated navigation system, especially in presence GPS signal outages. The filter adaptive theory adopted enhance positioning GPS/SINS system when available. A non-stationary time series analysis are used predict compensate for error...
Abstract The microstructure evolution and impact toughness of the coarse grain heat-affected zone (CGHAZ) TiNbV microalloyed steels were investigated by using a thermal simulation test. samples treated with various simulated welding cycles. phase constituents sizes analyzed electron backscatter diffraction analysis. CGHAZ consisted ferrite, acicular pearlite, bainite. have higher under lower heat input. This is because dominated volume fraction high-angle boundaries ferrites. presence...
Silicon Carbide (SiC) MOSFET has a fast switching speed and is sensitive to parasitic parameters, which easy cause higher turn-off transient overshoot voltage, directly threatens the stability safety of SiC devices causes excessive losses. To suppress voltage current surges oscillations during switching, this paper proposes an active drive circuit with auxiliary gate branch. By adjusting time tube driving branch, can be reduced in stage oscillation, increased non-sensitive reduce loss. A...
