Dynamic Analysis of Vibro-Impact Gear Drive System [PDF]
Transactions of the VŠB-Technical University of Ostrava, Mechanical Series, 2013 The mechanical systems with impact motion introduce a large class of mechanical devices. Impact oscillations are usually perceived as undesirable and harmful dynamic phenomena. However, the impact motions can have positive e ects (impact forming machines,

Optimization of the Vibro-Impact Capsule System
Strojniški vestnik - Journal of Mechanical Engineering, 2016 Optimization of the vibro-impact capsule system for the best progression is considered in this paper focusing on the choice of the excitation parameters and the shape of the capsule. Firstly, the fastest and the most efficient progressions are obtained through experimental investigations on a novel test bed.

Periodic Motion and Transition of a Vibro‐Impact System with Multilevel Elastic Constraints
Discrete Dynamics in Nature and Society, 2021 In this paper, a single-degree-of-freedom vibroimpact system with multilevel elastic constraints is taken as the research object. By constructing the Poincaré map of the system and calculating the Lyapunov exponent spectrum of the system, the stability ...

Vehicle’s transmission as a vibro-impact system
IOP Conference Series: Materials Science and Engineering, 2020 Abstract The article discusses a dynamic model of a dual-clutch transmission. The absence of a torque converter and the short duration of gear shifting (0.2 - 0.5 sec) in such transmissions allows to present the shifting process as impact interaction. As a result, the gear shift excites the oscillations of the gearbox output shaft. Thus,

Wake-induced response of vibro-impacting systems
Physics of Fluids, 2023 Abstract This study investigates the bifurcation behaviour of wake-induced vibro-impacting systems considering fluid-structure interaction (FSI). The primary structure and the near wake dynamics are modelled as a harmonic oscillator a Van der Pol oscillator, respectively, and are weakly coupled to each other.

Dynamical interaction of an elastic system and a vibro‐impact absorber [PDF]
Mathematical Problems in Engineering, 2006 The nonlinear two‐degree‐of‐freedom system under consideration consists of the linear oscillator with a relatively big mass, which is an approximation of some continuous elastic system, and of the vibro‐impact oscillator with a relatively small mass, which is an absorber of the linear system vibrations.

Global Dynamics of a Vibro-Impact Energy Harvester
Mathematics, 2022 In this paper, we consider a two-sided vibro-impact energy harvester described as a forced cylindrical capsule inclined at a horizontal angle, and the motion of the ball inside the capsule follows from the impacts with the capsule ends and gravity.
