Název :MODELLING AND VIBRATION OF MECHANICAL SYSTEMS WITH IMPACT MOTIONS
Autoři :DYK Š., BYRTUS M.
Abstrakt :The mechanical systems with impact motion introduce a large class of mechanical devices. Impact oscillations are usually perceived as undesirable and harmfull dynamic phenomena. However, the impact motions can have positive effects (impact forming machines, drop hammers, impact presses, etc.).
The contribution presents a methodology of modelling of mechanical systems with contacts which include both normal and friction forces. Such systems are described by non-smooth mathematical models, and specific numerical strategies have to be employed to solve them (smoothing method, switch method, event-driven method). The methodology will be tested on a simple mechanical system with impacts.
