Tautochronic bifilar pendulum torsion absorbers for reciprocating engines

摘要: Abstract A device for the dynamic absorption of torsional torque pulses acting on crankshaft a reciprocating engine is investigated herein. It composed set bifilar pendula arranged symmetrically crankshaft. These oscillate about their equilibrium positions when periodic act When small amplitude period oscillating made synchronous with disturbing torque, pendulum motion absorbs energy in pulses, so that angular velocity almost constant. This synchronism maintained at all speeds torques. However, non-linear effects destroy this larger torques (which cause oscillations pendula). In investigation, path followed by center mass sought such nth order and amplitudes up to maximum rated delivered engine. computer program describing dynamics crankshaft-pendulum system has been written used verifying theoretical investigation. Some numerical results an automobile are given.
