nonlinear vibration
- 1. • Sample analysis of nonlinear system, by finding equilibrium points and linearization of differential equation at each equilibrium point, using Taylor series. • Finding stable and unstable nodes around each equilibrium points.
- 3. • Determination of the potential function for unexcited system. • Finding stable and unstable points. • bifurcation diagram. • Numerical solution of equation of the motion by MATLAB software to find, time period of the system.
