A cracking and variation of the electrical insulation due to mechanical stresses during cooling and bending of HTS cables in cryogenic temperature is a serious problem.
Shen et al. (2011) studied the effect of forced cooling on laser bending of steel plates using finite element based numerical simulations.
A tool electrode device equipped with ultrasonic vibration function was designed and fabricated, for removal of the sludge from the bending cooling channel during machining.
She takes her title from a passage in Wright's "Black Boy: A Record of Childhood and Youth": I was taking a part of the South to transplant in alien soil, to see if it could grow differently, if it could drink of new and cool rains, bend in strange winds, respond to the warmth of other suns, and, perhaps, to bloom.
No changes were made to the wings other than the elimination of the air intakes for the oil cooler and the bending of the front wing spar into an inverted U-shape to clear the engine.
Although the pre-heating and interpass temperatures had a strong effect on the reaction forces, their effect on the bending moments upon cooling to room temperature was negligible.
There was a moment of ambiguity, the man poised there still, instead of bending to the cooler, and then there was a further question, which he didn't grasp until the man began rattling off the names of the beers he stocked, pointing as he did so to a line of bottles on the top row, ten or twelve different brands.
The new model combines thermal bending effects during cool-down, electromagnetic bending effects during magnet operation and current transfer in strands with filament fracture.
The basic shape control means of cold rolling strip mainly include roll tilting, roll bending, roll shifting, roll cooling, roll profiles optimization, rolling process optimization, and so on.
The 68 °F (20 °C) isotherm moves as far as latitudes 55° to 60° N, but, in the eastern Gobi and near the cool Pacific Ocean, it bends to the south.
