Application of Optimal Control Algorithm to Inertia Friction Welding Process
Inertia friction welding (IFW) is a rotational pressure welding process and is a technique commonly used in the production of aircraft engine shafts. With the ever-increasing achievable production tolerances in terms of the upset and angular orientation, it follows that a significant improvement in the control of these quality parameters is called for.

Effect of Variations in the Ring Thickness on the Dynamic Performance of the Bimetal Gears
ABSTRACT This study used a six‐degrees‐of‐freedom dynamic model to analyze the dynamic response of bimetal spur gears. Aluminum alloy forms the core of the bimetal gears, and a uniform‐thickness steel ring surrounds the teeth. Gear mesh stiffness of bimetal gears and the transmission error have been assessed using a numerical approach based on finite ...

ABSTRACT An experimental campaign was undertaken to demonstrate the applicability of the Bouc–Wen hysteretic model to describe the hysteretic system of the recent Framatome dimple‐less spacer grid design for Pressurized Water Reactors. The experimental setup subjected a reduced‐length fuel rod, supported at both ends by dimple‐less grids, to forced ...

Compression capacity of closely spaced double‐angle beam‐columns – Impact of joint stiffness
Abstract Usually, pinned ends are assumed to calculate the compression capacity of closely spaced double‐angle members. In reality, the joints used in practice provide additional rotational restraint at the member's ends, which significantly influence the compression member capacity of such built‐up sections.
