A Transformation Method for Solving Conservative Nonlinear Two-Degree-of-Freedom Systems
Figure 6
Amplitude-time response curves computed from the numerical integration solutions of (26) and those provided by substituting (11)1 into (7)2. The parameter values used to obtain these plots were , , and , with , , , , , and . Here, the gray solid lines and the black and the purple dots describe the numerical integration solutions of (26) by using, respectively, the Runge-Kutta and the EMHPM methods, while the blue dashed lines representing the numerical solutions obtained from the derived equivalent nonlinear equations of motion.
