NUMERICAL STUDY ON EFFECT OF PHASE ANGLE ON TORSIONAL AND LATERAL VIBRATIONS IN POWER TRANSMISSION SYSTEM EMPLOYING CARDAN SHAFT

A power transmission system driven by a Cardan shaft may experience severe vibration due to fluctuating rotational speed and moments transferred the final drives, determined level of angular misalignment phasing joint yokes. This study investigates potential an out-of-phase position displaced phase angle in attenuating vibrations. The governing equations representing dynamics are derived. torsional lateral responses numerically calculated over range input speeds. When vibration, is set equal maximum twist that occurs during in-phase position. Relative attenuation used investigate effects. effectiveness studied for different levels static misalignment. For considered system, results showed greater than 20 degrees, proposed arrangement could attenuate more 10 percent significantly vibration.
