    Interannual Variations of Upwelling in the East Coastof Guangdong and Its Correlation with Fisheries by WEN Hao, HONG Bo

    Published 2020-01-01
    “…Based on thedata of temperature, chlorophyll concentration and wind field from 2002 to 2016, marine catches inGuangdong Province from 2010 to 2018, this paper studies the interannual variation trend ofintensity and center of upwelling along the east coast of Guangdong Province, and discusses therelationship between upwelling intensity and wind speed, marine catches and upwelling intensity.The results show that in the past 15 years, the intensity of upwelling in the east coast ofGuangdong Province is generally strengthened; the center of upwelling is at 23.6°~23.7°N in allprobability, and there is a trend of northward movement.The coastal wind plays an important rolein the interannual variation of upwelling; excluding the damage of fishing structure and otherfactors, the correlation between marine catches and upwelling in Guangdong Province is very high,and the correlation coefficient reaches to -0.81.…”

    TORSIONAL VIBRATION ANALYSIS OF RV REDUCER BASED ON VARIATIONAL MODE DECOMPOSITION by ZHANG Jieting, YU Dong, LOU Junqiang, LUO Limin, GONG Linhuan, LI Guoping

    Published 2025-03-01
    “…To investigate the vibration performance of RV reducers and analyze the fault identification, the torsional vibration test bench for RV reducers was built.Based on the mechanical structure and transmission principles of RV reducers, the vibration frequencies under different operating conditions were calculated.The vibration signal of RV reducers of superior and inferior products was collected, and the acceleration signal of the torsional vibration under different speeds and swerves was collected.The torsional vibration signals were decomposed using the variational mode decomposition (VMD) to obtain the intrinsic mode function (IMF).The results demonstrate a high correlation between the extracted IMF features obtained through VMD and the vibration frequencies observed during the operation of RV reducers.Furthermore, by comparing the spectrum of IMF, the reasons behind the abnormal vibration in inferior RV reducers were identified.Ultimately, it is determined that the abnormal vibration in inferior RV reducers were caused by the excitation from the interaction between the auto rotation of the planetary gear and the crankshaft or the revolution of the cycloid gear.This study provides valuable insights for enterprises aiming to improve the transmission accuracy and product quality of RV reducers.…”
