Investigation of the Equivalent Representation Form of Strongly Damped Nonlinear Oscillators by a Nonlinear Transformation Approach

Figure 4

Amplitude-time response curves of (26), (27), and (31). Here, the solid line represents the numerical integration solution of (18), while the red and purple dashed lines represent, respectively, the numerical integration solutions of (27) and (30). The parameter values are 𝜈=0.1,  𝐴=1,  𝐵=1,  and 𝜅=0.1 with 𝑥₁₀=1.
