Sustainability and improvement of mechanical systems in energetic, material handling and conveying by using forensic engineering, environmental and robust design

Failures and malfunction of subassemblies and substructures of the earth moving machines for coal surface mining, machines for preparation and coal conveying in thermal power stations, traction systems and cranes with extreme performances (CEP), which are also used in container and bulk port terminals, are dominantly the consequence of mistakes in the analysis of dynamic loads and stress-strain conditions. So the part of the project is focused in engineering forensic researches of before mentioned events that dramatically reduce productivity and safety of mechanical systems in energetic, material handling and conveying (EMHCO). It is expected that from them came to the following results: improvement of structural solution of drive units, executive devices and support structures; improvement of the concept of maintenance; establishment of methodologies for reengineering, i.e. redesign and modernization, while simultaneously rising the level of technological, economic and environmental acceptability; lowering the cost of exploitation and extension of life cycle of machines and equipment in EMHCO. Considered systems are in the stage of reviewing the costs and environmental impacts. This is why a part of the research is related to technological solutions that will meet the performance, economic and environmental aspects such as: increasing the effectiveness and safety of machines throughout their life cycle, reducing harmful emissions (exhaust gases, noise and vibration).
