RELIABILITY ESTIMATION OF MECHANICAL SEALS BASED ON ARTIFICIAL HUMMINGBIRD ALGORITHM AND THREE⁃PARAMETER WEIBULL DISTRIBUTION by LI AnHong, ZHU JunHua, YU Ling

“…In order to quickly and accurately evaluate the reliability of mechanical seals,the three⁃parameter Weibull distribution was used to model the mechanical seal failure data.The reliability evaluation problem of mechanical seal was transformed into a constraint optimization problem,and a reliability evaluation method based on artificial hummingbird algorithm(AHA)was proposed.Through numerical simulation and case analysis,maximum likelihood estimation(MLE),improved Harris Hawks optimization(IHHO)algorithm and AHA were used to compare calculation accuracy and operational efficiency in solving the Weibull distribution parameter estimation problems.The results show that the parameter estimation using AHA has advantages of faster convergence speed and higher accuracy,and it can shorten the optimization time and improve the accuracy compared with MLE algorithm and IHHO algorithm,which provides a new and efficient method for Weibull parameter estimation of mechanical seals.…”

Communication-radar coexistence design based on block diagonalization by Kaifeng HAN, Litao HUANG, Li CHEN, Zhiqin WANG

“…Aiming at the problem of coexistence of communication and radar at the same frequency， a block diagonalization design scheme was proposed.Firstly， an optimization problem was established to maximum the communication system’s sum rate subject to no interference at the radar side and the power budget.To solve this problem， the constraint that the interference between communication users is zero was introduced， so that the non-convex original problem could have a closed-form solution.Then， based on the restriction on the number of base station’s transmit antennas caused by introducing the constraint， two other algorithms were proposed to further consider the block diagonalization design when the constraint was not met.The simulation results show that the proposed algorithms can introduce the constraint to solve the original problem in various scenarios with relative-low computation complexity， which can be implemented in practice.…”
