Pretensioning

pretensioning

[prē′ten·shən·iŋ]
(engineering)
Process of precasting concrete beams with tensioned wires embedded in them. Also known as Hoyer method of prestressing.

Pretensioning

Prestressed concrete in which the tendons are tensioned before the concrete has hardened, and generally before it is cast; the concrete is cast around the wires which are flame-cut after the concrete has hardened.

pretensioning

A method of prestressing reinforced concrete in which the tendons are tensioned before the concrete has hardened.

The operator selects the correct pressure from the machine documentation and clamps the screw outside the extruder in the pretensioning device.
Very high initial stiffness (or joint resistance) due to bolt pretensioning is shown in Figures 4.
65 kNm for the joints with 5 kN, 10 kN, and 15 kN of pretensioning force per bolt, respectively.
61 kNm, respectively, for the joint with 0 kN, 5 kN, 10 kN, 15 kN of pretensioning.
The seat belt can thereby not only be tightened at the onset of a crash as with a regular pretensioning system, but the tightening can be adjusted to the severity of the crash.
TRW technologies in air bags, propellants, modules, seat belts, pretensioning devices, steering wheels, sensors and diagnostics are becoming increasingly sophisticated and adaptable to a wider variety of crash situations," said Hubert Kuhlenkamp, TRW director of engineering for inflatable restraint and steering wheel systems in Europe.
