A study looked at a vibro-bounce system with three degrees of freedom. They analyzed the system near a point where a special type of bifurcation occurs. The researchers found that near this point, the system can transition from one type of motion to another, involving both single and double impacts. Through simulations, they observed a unique torus doubling bifurcation, where the system's behavior changes in an interesting way. This study provides insights into how complex motions can arise in vibro-bounce systems.
