In order to investigate torsion pendulum dynamic characteristics of scraper chain system,dynamic model of scraper chain system was established by using finite element method.Numerical simulation read more was analyzed for dynamic characteristics of scraper chain system by applying pulse load,step load and slope load.Torsion pendulum dynamic charact
Cross-linked polyethylene (XLPE) carries a high fire risk.In this paper, a cone calorimeter is used to carry out radiation ignition experiments, and the heat release rate (HRR), mass loss rate (MLR) and other combustion parameters of XLPE cables under three kinds of radiation intensity are measured.By comparing the ignition time and HRR of samples
Understanding vaccine hesitancy is becoming increasingly important, especially after the global outbreak of COVID-19.The main goal of this study was to explore the differences in vaccination conspiracy beliefs between people with a university degree coming from different scientific fields-Social Sciences & Humanities (SH) and Science, Technology, E
Phthalic anhydride was used to corrode the aramid fibers (AFs) in order to improve the interfacial compatibility between AFs and recycled polyethylene terephthalate (R-PET).Besides, the intrinsic iphone 13 pro max price florida viscosity and the mechanical properties of the composites of AFs/R-PET could be improved to realize the transformation fro
