Essay

The object is a dynamic state of the system "road-header with axial cutting head - rock face". The aim is to increase the level of engineering performance of road-headers at computer-aided design stage based on establishment of regularities of stochastic components of loads on picks and on using of this regularities at the development of the mathematical model which is provided estimation of decreasing of dynamic loads and optimization of parameters of axial cutting head. Methods of researches: the system approach with use of methods of design of experiments, theory of probabilities and mathematical statistics, mathematical simulation, mathematical programming, experimental method of strain measurements. It is developed the mathematical model of the system "road-header with axial cutting head - rock face", differenced by accounting the stochastic components of load on picks. It is first time researched the influence of the stochastic components on stress loading of subsystems of the header. Sphere ofuse: the enterprises of mining machinery manufacturing, scientific researches and educational process.
