Experimental Investigation of the Dynamic Deformation of Wind Turbine Blades Based on 3D-Digital Image Correlation by Liru Zhang, Jing Jia, Shibing Shao, Wei Gao, Dachuan Niu

“…The experimental results show that the dynamic waving deformation of the blade shows the trend of increasing and then decreasing with the increase in wind turbine rotational speed and incoming wind speed, and when the rotational speed reaches 500 r/min and the incoming wind speed reaches 9 m/s, the blade deformation reaches the maximum value; the dynamic waving deformation of wind turbine blade decreases with the increase in the elastic modulus of the blade and the degree of the decrease decreases gradually; the dynamic deformation of is predicted by the multiple displacement distribution of different blades under different operating conditions, and is obtained by the fitting of the experimental data. …”

Application of a Frequency Converter in Electric Automatic Control of Central Heating by Jingwen Yin, Guifeng Zhang

“…The experimental results show that the temperature control strategy using a frequency converter automatic compensation method reduces the energy waste caused by manual regulation to a certain extent. When the speed of a water pump motor decreases to 4/5 of the original, the power consumption will decrease to about 52% of the original and save about 48% of the power; When the speed drops by 3/5, the power consumption is about 22% of the original, saving about 78% of the power. …”

Kinematic analysis of the back squat at different load intensities in powerlifters and weightlifters by Valerio Giustino, Domenico Savio Salvatore Vicari, Domenico Savio Salvatore Vicari, Flavia Figlioli, Flavia Figlioli, Marco Gervasi, Eneko Fernández Peña, Naima Schifaudo, Mattia Tedesco, Patrik Drid, Antonio Paoli, Giuseppe Battaglia, Giuseppe Battaglia, Antonino Bianco, Antonino Patti

“…., 60%, 70%, 80%, 90%, 100%) of the 1-RM. An action camera recorded the execution of each BS trial in the sagittal plane and, afterward, the videos were analyzed by measuring the range of motion (ROM) of hip, knee, and ankle for the angular kinematics, and the timing, distances, speeds, and accelerations of the barbell for the linear kinematics.ResultsRegarding the angular kinematics, no significant differences were found in the parameters in the starting and ending positions among the 5 trials, while a significant decrease was found in the hip relative angle (p = 0.026) in the maximum flexion position as load intensity increased. …”
