AB - Establishing the Lagrangian equation of double complex pendulum
system and obtaining the dynamic differential equation, we can analyze the motion
law of double compound pendulum with application of the numerical simulation
of RK-8 algorithm. When the double compound pendulum swings at a small angle,
the Lagrangian equation can be simplified and the normal solution of the system
can be solved. And we can walk further on the relationship between normal
frequency and swing frequency of double pendulum. When the external force of
normal frequency is applied to the double compound pendulum, the forced
vibration of the double compound pendulum will show the characteristics of beats.
