A Differential Algebraic Method to Approximate Nonsmooth Mechanical Systems by Ordinary Differential Equations

Figure 7

Simulation results of Example I by using (37) integrated by RK4 with the timestep size 0.001 s. The parameters are chosen as 𝐾₁=𝐾₂=1×10⁵ N/m, 𝛽₁=𝛽₂=4×10⁻³ s, and 𝛼=2.8×10⁻³ s. Graphs (e) and (f) are enlarged views of graphs (a) and (d), respectively.
