Dynamic Analysis of Rotating Pendulum by Hamiltonian Approach
Najeeb Alam Khan, Nadeem Alam Khan, Fatima Riaz
Source abstract
A conservative system always admits Hamiltonian invariant, which is kept unchanged during oscillation. This property is used to obtain the approximate frequency-amplitude relationship of the governing equation with sinusoidal nonlinearity. Here, we applied Hamiltonian approach to obtain natural frequency of the nonlinear rotating pendulum. The problem has been solved without series approximation and other restrictive assumptions. Numerical simulations are then conducted to prove the efficiency of the suggested technique.
