Experimental Study on Friction-induced Vibration of Water-lubricated Rubber Stern Bearing at Low Speed

摘要

When the stern bearing is operating,friction-induced vibration occurs because of friction and has some potential danger.In vibration test,it discovers that the friction-induced vibration appears at low speed and the vibration has the nature of randomness.The vibration response is nonlinear and a negative correlation is found between vibration intensity and rotational frequency.
