differential equation of three-line pendulum in large swing angle motion and the
approximate treatment method of linear vibration with small swing angle are given. Under
the approximate condition about the structural dimensions of the three-line pen- dulum，the motion
differential equation，period and position probability density distribution of the three-line
pen- dulum under two different conditions of large swing angle and small swing angle are discussed.
