Experimental Study on Individual and Group Evacuation of Passengers from an Aircraft Cabin in the Pitch/Roll State

open access: yesAerospace, 2023
After an aircraft is forced to land, it is easy for it to become stuck in a tilt state of pitch or roll. The pitch/roll state of the aircraft cabin is a critical factor affecting the safe evacuation of the cabin. However, evacuation therein deserves more

Rolling Force Prediction of Hot Rolling Based on GA‐MELM [PDF]

open access: yesComplexity, 2019
In the hot continuous rolling process, the main factor affecting the actual thickness of strip is the rolling force. The precision of rolling force calculation is the key to realize accurate on‐line control. However, because of the complexity and nonlinearity of the rolling process, as well as many influencing factors, the theoretical analysis of the ...

Investigation of force parameters during rolling in relief rolls

open access: yesJournal of Chemical Technology and Metallurgy, 2023
The paper presents the results of theoretical studies of the force parameters of thick-sheet blanks rolling in relief rolls. Empirical dependences were obtained to determine the average rolling pressure and force. When studying the pressure, the approach of replacing the defonnation scheme with a flat analog was used.
