EFFECTS OF ADDING BRACKET JOINT ON THE RIGIDITY AND STRENGTH OF BUS T-JOINT STRUCTURE by DENG TengShu, CHEN MingNian

“…This paper discussed the effects of triangle bracket size and four forms of triangle brackets（ double brackets added at vertical rod single side,double brackets added at vertical rod both sides,single bracket added at vertical rod both sides,single bracket added at vertical rod crossing symmetric sides） on the rigidity and strength of bus T-joint structure. The calculation by finite element method and experimental analysis showed that: 1Only double brackets added at vertical rod both sides in the four forms of triangle bracket can evidently increase both the rigidity and strength of bus T-joint,2Under the bending loads two forms can be selected compatibly for T-joint structure,3Under the torsion loads double brackets added at vertical rod both sides should be selected for T-joint structure. …”

Multi-objective Optimization Design of RV Reducer Considering the Cycloid Gear Profile Modification by Wang Quan, Zeng Lilei, Qin Zhengzheng

“…In view of the fact that the influence of cycloid gear profile modification on contact force is not taken into account in the structural design of RV reducer，a multi-objective optimization design method for the structure of RV reducer considering cycloid gear profile modification is proposed.Combining the theory of tooth profile modification with the calculation of contact stress of cycloidal gear，considering the factors of volume，efficiency and contact stress，an optimization mathematical model with small volume，high efficiency and low contact stress of cycloidal gear as multi-objective function is established.The solution is carried out by using NSGA-II algorithm，and compared with single-objective optimization method.The results show that compared with the original design，the volume of RV reducer decreases by 21.24%，the efficiency increases by 2.03%，and the contact stress of cycloid wheel decreases by 20.26%.Meanwhile，the multi-objective optimization method has higher comprehensive performance than the single-objective optimization method.…”

Research on Early Warning of Flash Flood Disaster Based on Multi-Source Rainfall Data Integration by LI Guanyi, YU Zexing

“…Flash flood is the main disaster that causes casualties in China,and it has the characteristics of abruptness,unpredictability,and harmfulness.In this study,the accumulated rainfall in the humid area of South China in different periods is calculated based on the integrated multi-source rainfall data,and the early warning of flash flood disasters is analyzed according to the dynamic rainfall early warning index analysis method.The method is applied to the small watershed of Maofeng Town in Nanxiong city and Bijia forest farm in Qingyuan city.The results show that compared with the actual time of flash flood disaster in the studied area,the warning is issued 3 h and 0.5 h in advance by the dynamic rainfall early warning index analysis method based on the multi-source rainfall data integration,which effectively prolongs the prediction period of flash flood disasters and gains more time for early warning release and personnel transfer.…”

Planetary Gearbox Fault Diagnosis based on LMD Sample Entropy and ELM by Zhang Ning, Wei Xiuye, Xu Jinhong

“…In order to solve the difficult problem of early fault feature extraction of planetary gearbox and consider that the planetary gearbox vibration signal is coupling and nonlinear，and the signal has multiple transmission paths，a planetary gearbox fault diagnosis method based on Local Mean Decomposition（LMD） and Sample Entropy and Extreme Learning Machine（ELM） is proposed.Firstly，the vibration signal is adaptively decomposed into a plurality of PF components by LMD，and the first four PF components including the main fault information are selected in combination with the correlation coefficient and the variance contribution rate.Secondly，the Sample Entropy of the signal is calculated to form a feature vector.Finally，the feature vector is input into ELM for fault classification.Experiments are carried out on the planetary gearbox test bench，compared with the probabilistic neural network classification algorithm，and compared with the feature vector based on Singular Value Decomposition （SVD）.The results verify the effectiveness of the proposed method.…”
