Self-tuning vibration absorber

A method of vibration dampening, including the steps of:

• detecting a vibration of a primary system and detecting a vibration of a carrier rod assembly;
• analyzing the vibrations to determine a phase difference between the vibration of the primary system and the vibration of the carrier rod assembly;
• adjusting a hollow shafted motorized tuning mechanism in the carrier rod assembly, by actuating the motor to move the motorized tuning mechanism to tune the phase difference between the vibration of the primary system and the vibration of the carrier rod assembly to 90 degrees and then turning the motor off;
• and
• dampening the vibration of the primary system and the carrier rod assembly.

A method of reducing hunting motion in railcars, including the steps of:

• detecting a vibration of a railcar and detecting a vibration of a carrier arm assembly;
• analyzing the vibrations;
• adjusting a hollow shafted motorized tuning mechanism in the carrier arm assembly to tune a phase difference between the vibration of the railcar and the vibration of the carrier arm assembly to 90 degrees;
• and
• dampening the vibration of the railcar and the carrier rod assembly to reduce hunting motion.
