The Reset Integrator is a unique friction model that can efficiently simulate stick-slip motion by representing the microscopic contact as a single elastic bond [1]. The Reset Integrator model has several advantages including 1) accurate representation of stick-slip behavior, 2) it's more application-independent than the Karnopp model, and 3) it has more input parameters than the Dahl model for capturing system-specific behavior [1]. Refer to the research of Rybkiewicz and Leus for an example of applying the Reset Integrator model and comparing its performance with similar models [2].
I've structured the Simulink block diagram such that users can recreate Figure 11 from the original paper based on the single-body spring-mass example [1]. Representative plots are shown below to demonstrate the model performance.
Figure 1: Friction force profile generated by pulling a spring-mass system along a countersurface resulting in stick-slip motion. The model parameters are configured according to Table 1 from the original paper [1]. Solver settings ode45, rel tol 1e-4, simulation time 5 s.
Figure 2: Output position profile of the mass subject to stick-slip motion, corresponding to the friction profile in Figure 1.
