OPTIMIZATION OF FATIGUE LIFE OF TRANSMISSION SHAFT BASED ON RESPONSE SURFACE METHOD
Published 2022-01-01“…Through the analysis of the actual measured load, the cause of the fatigue failure of the drive shaft in advance is the inconsistent output load of the left and right splines. The finite element model of the transmission shaft is established by using finite element software, and the maximum stress at the root of the right tooth of the transmission shaft is obtained, which is the weak part of the transmission shaft. …”

Dynamics Modeling and Response Analysis of Gear-screw Actuators of Tiltrotor Aircrafts
Published 2024-11-01“…On this basis, an analysis of the dynamic behavior of the gear-ball screw actuator system was conducted, along with an exploration of the influence of structural parameters of the ball screw pairs on the output response. The results show that the axial vibration response of the ball screw decreases with an increase in the helix angle, while it follows a trend of initial increase followed by decrease with an increase in the contact angle.…”

Application of NARX in Seepage Prediction of Earth-Rockfill Dams
Published 2022-01-01“…Seepage monitoring is an important means to master the safety state of a dam.As the seepage pressure of earth-rockfill dams lags behind the reservoir water level,a nonlinear auto-regressive neural network with exogenous inputs (NARX),a network characterized by delayed input,is introduced to effectively predict the seepage pressure of the dams.In the case of a reservoir dam,with the influencing factors such as the reservoir water level and rainfall in a certain period of history as the input sequence and the measured value of seepage pressure as the output sequence,the multi-factor and single-factor models of the NARX network are built separately for fitting training and multi-step prediction.Then,the prediction results are compared with those of the traditional regression model and the traditional BP neural network.The results reveal that the NARX model outperforms the two traditional models under the three accuracy indexes of RMSE,MAE,and MAPE.Moreover,the NARX model still has good performance under the condition of a single factor.The delayed input characteristic of the NARX network can simulate the hysteresis of dam seepage to a certain extent,and the network has a good application effect for seepage pressure prediction of earth-rockfill dams.…”

Hypothalamic AMPK as a Regulator of Energy Homeostasis
Published 2016-01-01“…Hypothalamic AMPK restores energy balance by promoting feeding behavior to increase energy intake, increasing glucose production, and reducing thermogenesis to decrease energy output. Besides energy state, many hormones have been shown to act in concert with AMPK to mediate their anorexigenic and orexigenic central effects as well as thermogenic influences. …”
