On the Rolling of Uranium Rods by Grooved Rolls

open access: yesJournal of the Atomic Energy Society of Japan / Atomic Energy Society of Japan, 1959
Some basic studies on the rolling of uranium rods were carried out as a part of preliminary study for the fabrication of natural uranium fuel rod to be used for JRR-3. Two different sequences of groove were adopted; one was the ordinary "Oval-square," and the other was the "Gothic." Because of the underfilled deformation of uranium in the oval groove ...

Evaluation and improvement of tire rolling resistance and grip performance based on test and simulation

open access: yesAdvances in Mechanical Engineering, 2020
In order to clarify the contradictory mechanism between tire rolling resistance and grip performance, ten (10) 205/55 R16 radial tires with different tread patterns were selected as the research objects. Using VIC-3D non-contact strain measurement system,

PLASTIC DEFORMATION IN GROOVED ROLLS [PDF]

open access: yes, 1955
The direction and extent of lateral deformation during the rolling of rod in grooved rolls was investigated. Composite uranium ingots and laminated ingots of colored modeling clay were used to investigate the deformation in diamond, oval-round, hand-round, and the FMPC breakdown rolls.

Calculation method for the static carrying curve of double-row different-diameter ball slewing bearings

open access: yesScience Progress, 2023
A method for calculating the static carrying curve of a double-row different-diameter ball slewing bearing was proposed. The relationship between the internal maximum rolling element load of each row and the combined external axial load and tilting ...
