bulb stiffener

An improved composite stiffener and methods and tooling used to form the same. The stiffener includes one or more base flanges, a composite rod extending in an axial direction, a bulb cap

Bulb flats are the plate stiffener of choice for the shipbuilding industry, due primarily to their excellent strength to weight ratio and the fact that 

Bi-directional Stiffener Welder • Welds flat, angle, tee, and bulb type stiffener configurations. • Fillets up to 5/16 inch (8 mm). • Weld speeds up to 70 IPM (1778 mm). • Achieve high quality, uniform, continuous or intermittent welds on both sides of the stiffeners simultaneously. • The machine can be equipped with various weld

It maintains the flap's natural airfoil shape by eliminating the unsightly bulb and resultant drag found on common trailing edge stiffeners.

This paper describes fatigue tests at stiffener end connections with bulb flats and angle bars and focuses on the question how far bulb flats are also prone to fatigue in view of the reduced

Bulb flats are being used as plate stiffeners especially in the shipbuilding industry. Our supply width ranges from 60mm to 430mm, and can be supplied 

An investigation of the fatigue strength of three bulb plate stiffener joints is discussed. In addition to the usual joint with completely welded bulb, two further configurations are considered: one having a weakened bulb and another one having extra reinforcement to compensate for the unwelded bulb. The fatigue life for the usual and for the

An improved composite stiffener and methods and tooling used to form the same. The stiffener includes one or more base flanges, a composite rod extending in an axial direction, a bulb cap surrounding the composite rod, and an upright web extending from the one or more base flanges to the base cap. The upright web includes a non-linear profile in the axial direction providing

The use of bulb flat plate stiffeners in ship design is said to reduce building time and maintenance cost. Companies that produce bulb flat plate stiffeners manufacture each stiffener as a single unit, which reportedly results in less production cost compared to welded or fabricated stiffeners.
