In order to solve the problem of low energy utilization rate small UAV, we carried out analysis 80kW series hybrid system, expounded configuration scheme aviation built corresponding Matlab/Simulink simulation model, and designed optimal working electrical calculation method bidirectional half-bridge DC/DC converter control strategy for vector permanent magnet synchronous generator. Through results different operating points each subsystem, feasibility full-control rectifier SVPWM algorithm...
The electric propulsion system for aircraft has garnered increasing attention due to its clean and efficient characteristics, providing more flexible sustainable solutions while achieving zero emissions low noise. As a critical component of propulsion, the machine must provide corresponding electrical energy at different operating stages, making thermal management design crucial. This paper focuses on analysis air-cooled permanent magnet synchronous machine. Computational fluid dynamics...
In this paper, the finite element method (FEM) based on GTN model was used to investigate in-plane/out-of-plane constraint and strength mismatch effects local fracture resistance of A508/Alloy52Mb bimetallic joint. The J -resistance curves, crack growth paths stress-stain distributions in front tips were calculated for cracks with different constraints mismatches. results show that interface joint is sensitive effects. With increasing in-plane (crack depth a/W ), out-of-plane (specimen...
Abstract In this work, the constraint parameter A p based on crack‐tip equivalent plastic strain was calculated by finite element analyses for cracks located at different locations in two interface regions a dissimilar metal weld joint (DMWJ). The capabilities of characterizing material and establishing correlation with fracture toughness region have been examined. results show that can characterize effect caused mismatch initial crack positions regions. Based , lines formulae DMWJ be...
The effects of toughness mismatch on failure behavior bi-material interfaces have been investigated by FEM numerical analyses based GTN damage mechanics model. results show that the fracture resistance and crack growth path are related to strength mismatch, interaction between them determines interfaces. For interface cracks with higher lower mainly controlled mismatch. While for dominated

The neural network (NN) is extensively used for error predication and compensation in CNC machining. However, the training samples are finite have some noises which limit accuracy of network. Furthermore, weight matrixes valve values NN fixed generalization performance trained NN. To solve problems, optimization techniques proposed this paper. A standardized formula to standardize samples. data filter designed eliminate noise. correction strategy realize
This paper presents a new scheme of digital calibration for 14-bit 125-MS/s pipelined ADC. The proposed corrects the linearity errors resulted from capacitor mismatches, finite Operational Transconductance Amplifier (OTA) gain and OTA's settling error. method is based on radix-based calibration, Pseudo-random Noise (PN) sequence injected into Multiplying DAC (MDAC) to extract equivalent radix. According system, simulation results show that when prototype ADC sampled at 125 MS/s, Spurious...
