Dynamics of material handling and conveying machines

The main objective of this course is to achieve competence of PhD students to master the principles of analysis dynamic behavior of support structures of material handling machines and conveyors and that is able to be incorporated into complex processes of their behavior under the action of various external loads.

By completing this course student acquires ability to: • model supporting structures of material handling and conveying machines • define natural frequencies of material handling and conveying machines by applying Finite Elements Method • analyse external loads of material handling and conveying machines • evaluate the set up model • get a dynamic response of dynamic system to external loads • analyse alternative solutions in modeling process • present obtained results of the research

Introduction into dynamics of material handling and conveying machines. Modeling support structure of a machine and drive units. Dynamic factors according to the existing standards. Discrete and continual models. Analysis of external loads (excitation). Obtaining natural frequencies of support structure of a material handling machine or conveyor by using Finite Elements Method. Effects of moving load on dynamic behavior. Moving load models: moving force, moving mass, moving oscillator. Wind effects on dynamics of structures. Obtaining dynamic response of the support structures of material handling and conveying machines. Analysis of obtained results. Evaluation of models. Comparison between various modeling approaches on dynamic response of a structure.
