Particle damping aircraft wheel torque bar

A brake assembly for mounting on an axle comprising:

• a brake rotor;
• a wheel including a wheel disk comprising a hub, and having an outboard lip and an inboard lip defining a rim about the wheel disk extending axially with respect to the hub;
• and
• a particle damped torque bar configured to engage with the wheel disk and rotate the brake rotor comprising:
• a body comprising a box beam structure;
• the body having a neck portion at a first end and an I-beam structure at a second end,
• wherein the box beam structure extends between the neck portion and the I-beam structure;
• and
• a cavity within the box beam structure configured to encapsulate a particulate material therewithin,
• wherein the cavity is only partially filled by the particulate material, and
• wherein the cavity further comprises a plurality of at least one of baffles or partitions configured to reduce vibration g-levels response to an interaction between the particulate material and the baffles.

A method of manufacturing a particle damped torque bar, the method comprising:

• forming a box beam structure extending between a neck at a first end and an I-beam structure at a second end;
• forming a hollow within the box beam structure between the neck and the I-beam structure;
• disposing a particulate material within the hollow;
• and
• coupling a top surface over the hollow to generate a box beam structure and a cavity encapsulating the particulate material within the box beam structure
• wherein the cavity is only partially filled by the particulate material, and
• wherein the cavity further comprises a plurality of at least one of baffles or partitions configured to reduce vibration g-levels by greater than 10% across a frequency range of 10 Hz to 4,000 Hz in response to an interaction between the particulate material and the baffles.
