A Transformation Method for Solving Conservative Nonlinear Two-Degree-of-Freedom Systems
Figure 1
Amplitude-time response curves computed from the numerical integration solutions of (13) and those provided by substituting (14)1 into (13)2. The parameter values used to obtain these plots were , , , and , with , , , and , and , , , and . Here, the gray solid lines describe the numerical integration solutions of (13), while the blue dashed lines represent the numerical solutions obtained from the derived equivalent nonlinear equations of motion.
