行星齿轮传动单侧板转臂的有限元分析 by 袁齐, 王勇

“…One-sided plate pivoted arm in closed planetary gear transmission is normally integral.A method of processing the planetary gear shaft and the plate respectively and joining them in the way of interference fit to form a separated one-sided plate pivoted arm is studied.So that integral one-sided plate pivoted arms can be replaced and the manufacturability can also become easy.The structural analysis of assembled separated one-sided plate pivoted arm is conducted using finite element analysis software ANSYS considering the interference fit and the load on planetary gear shaft.The deformation and variation rule of stress as well as its distribution are revealed when the separated pivoted arm is joined with different magnitude of interference.As a result the optimum interference fit is obtained.The method of optimizing design of pivoted arm is feasible and the application effect is good.…”

Improved transmit beamforming design based on ADMM for low probability of intercept of FDA-MIMO radar by Pengcheng GONG, Yuntao WU

“…Considering the low probability of intercept problem that the signal-dependent interference and the target were located in the same angle, an improved transmit beamforming design based on the alternating direction method of multipliers (ADMM) was proposed for multiple-input multiple-output with frequency diverse array radar.The transmit energy was minimized at the target under constraints of the energy at each transmitter and signal clutter-plus-noise ratio requirement.Subsequently, a cyclic algorithm was developed to tackle the non-convex design problem.Firstly, the optimal receive filter was obtained by generalized Rayleigh quotient.And then the transmit beamforming was optimized by employing auxiliary variables and ADMM to solve quadratic programming problem with fractional inequality constraint.Moreover, both the convergence and computational complexity of the proposed algorithm were discussed.Simulation results show that, compared with the semi-denite programming method, the proposed method not only attains the given antenna power, but also achieves the better mainlobe focusing performance at the target.Furthermore, the null levels at the clutter locations and the jamming directions obtained by the proposed method are -50 dB above.…”

Research of Transmission Line Crosstalk Influence Factors Based on TLM by Qianying WANG, Junwen LU, Chao ZHOU

“…The research results show that the cable crosstalk effect decreases with the increase of the cable interval distance, however, the degree of crosstalk cannot be reduced effectively by increasing the interval distance when the distance increases to 10 cm; the degree of crosstalk increases with the increase of the height of the transmission line from the ground and the length of the transmission line, which increases linearly with the increase of the height of the transmission line from the ground; and changes periodically with the change of the signal frequency, the change frequency of which is about the corresponding frequency value when the electromagnetic wave wavelength is twice the cable length, and the maximum crosstalk voltage appears near the integer multiple of the frequency value;compared with increasing the interval distance, choosing the cable with shielding layer is the key to reduce the crosstalk effect; the crosstalk voltage can be reduced to 0.02 V by the coaxial line which has the optimal anti-interference performance.…”

Secure transmission for NOMA downlink based on short packet communication by Gangcan SUN, Shaoke ZHAO, Wanming HAO, Zhengyu ZHU

“…For the low-latency requirements of Internet of things (IoT) business, short packet communication (SPC) and non-orthogonal multiple access (NOMA) were combined to study the problem of secure transmission in the multi-user NOMA system with eavesdroppers.With the maximizing the secure throughput of weak uses as the objective, considering the user decoding error probability constraint, total power constraint and power allocation constraint, a low-complexity power allocation algorithm was proposed to realize secure transmission.In order to solve the problem caused by complex objective function formula and unreliable serial interference cancellation (SIC) technology, the proof that the compactness of the constraints was necessary to find the optimal solution.Under the constraint of maximum decoding error probability, the power constraint was transformed and calculated to obtain the strict limit of transmitting power for strong users, and the transmit power search set from base station to strong user was derived.Then, the one-dimensional search algorithm was used to allocate power resources to maximize the throughput of weak users.Simulation results prove that the proposed algorithm can effectively improve the security throughput of weak users in the system.…”

Adaptive anti-jamming technologies based on direct sequence spread spectrum and single carrier frequency domain equalization by Fanglin GU, Yuzhen HUANG, Ying ZHAO, Haitao ZHAO, Jibo WEI

“…To solve the performance limitation of direct sequence spread spectrum system in complex multipath environment, an adaptive anti-jamming spread spectrum framework that organically combines single carrier frequency domain equalization (SCFDE) and direct sequence spread spectrum (DSSS) technologies was proposed.The frequency multipath fading was overcame by frequency domain equalization, and the transmission rates and high reliability was reconfigured by deploying variable spread factors.Moreover, the inherent fast Fourier transform process was made full use at the receiver to realize the adjoint detection and analysis of interference intensity, interference type and other information, etc.Then, the frequency domain bearing point online was optimized and selected to improve the adaptability to the interference, especially blocking interference.The simulation results show that the proposed direct spread spectrum waveform based on SCFDE has good communication performance in both Gaussian and multipath environments, and the notch of some frequency bands has little impact on the communication performance, which verifies the effectiveness of anti-jamming by adaptive optimizing information frequency domain bearers.…”
