The modelling of accumulation and dissipation of energy in mechanical drive system

This paper presents a modelling of accumulation and dissipation energy in simple drive system. The simple drive system is presented by laboratory stand designed for calculate fatigue life of material for bending and rotation tests pieces. The laboratory stand was prepared to diagnosis of fatigue life of material by use energetic methods. This idea was submitted as utility model to Polish Patent Office. This laboratory stand gives ability to research a influence of change of fatigue life for energetic symptoms (like: temperature of material, vibration, Acoustic Emission, rotary speed, electrical energy). This paper presents influence of change of fatigue life for rotary speed. The rotary speed is value describing effect of accumulation and dissipation energy in drive system (in material). A difference between energy taken from power supply and consumed for giving rotary speed is used for fatigue of material. This simple theory is presented and modelling in this paper. The next paper (in this book) describes results of research that could verify this theory.
