Metoda absolutnih vozliščnih koordinat v dinamiki sistema togih teles z vključitvijo kontaktnih razmer

Skrinjar, Luka (author), Slavič, Janko (mentor)

Raziskava predstavlja pristop k reševanju dinamskih sistemov, ki so sestavljeni iz togih in prožnih teles ter povezani z ustreznimi kinematičnimi povezavami. Za določitev dinamskega odziva je razvita in numerično ter eksperimentalno ovrednotena kinematična povezava čepa v vodilu z zračnostjo, ki je nato uporabljena pri izdelavi dinamskega sestava, sestavljenega iz togih in prožnih teles. Obravnavani dinamski model, ki temelji na realni inženirski aplikaciji, je uporabljen v procesu analize vpliva pred-napetja na dinamski odziv.

• Title: Absolute nodal coordinate formulation in rigid multibody dynamics with inclusion of contact situations

Abstract

This research presents the approach to modeling of multibody systems assambled of rigid and exible bodies and interconnected with adequate kinematic constraints. With a goal to evaluate the dynamic response a kinematic constraint, pin-slot clearance joint, is developed. The developed pin-slot clearance joint is numerically and experimentaly researched and then used when modeling a multibody system assmabled of rigid and exible bodies. The dynamical system in focus is based on the real engineering application and used to study the effect of pre-stress on dynamical response.
