| Innovative approaches to increase the lifetime and reduce the energy consumption of cutting tools in wood processing in forestry | |
| Program: | SRDA |
| Project leader: | RNDr. Džupon Miroslav, PhD. |
| Annotation: | The project will address the issue of the use of methods and procedures for the modification of cutting tools for wood processing in forestry. The result will be an increase in their lifetime and a reduction in emissions and energy consumption of forestry machinery and equipment. The main objects of research will be tools for primary wood processing, modification and processing of forestry biomass for energy purposes, such as splitting and chipping tools, tools for cross-cutting wood, etc. The main task of the project will be the design of procedures and methods for the modification of exposed functional surfaces of the tools. Ensuring a higher quality of functional tool surfaces in the context of reducing friction and eliminating adhesion, provides a prerequisite for reducing the load on machinery equipment and thus reducing emissions and energy consumption in a given production. Analyses will be carried out on the tools – FEM analysis in order to determine the stress-strain state, on the samples analysis of the state of the material in terms of physical properties, microstructure, mechanical properties and resistance to adhesive wear in wood-metal interaction and also abrasive wear. Based on the results of the analyses carried out, innovative surface treatment procedures will be proposed for the exposed functional surfaces to guarantee an increase in their functional lifetime. These will be applied to samples and laboratory tested by relevant test procedures. From the results of the laboratory tests, a selection will be made of the most appropriate non-conventional innovative procedures, which will be applied to the tools and tested on the equipment under forestry operating conditions. In doing so, it will be observed how the modifications in question affect the energy consumption of forestry machinery and equipment. Part of the project solution will be to ensure industrial-legal protection of the original solutions. |

| Annotation: | The global trend to reduce emissions has forced car producers to think about other types of propulsion thaninternal combustion engines. A significant direction in which the world is currently moving in this area is thereplacement of internal combustion engines with electric car drives. This fact has led and it is still leading to a greatexpansion in the production of car batteries, which would allow the longest possible range of electric cars. Besidesthe capacity of the batteries, the efficient use of stored energy in electric vehicle drives has a significant effect onthe range of cars as well. This project aims to reduce losses and increase the efficiency of electric drives.Increased efficiency and reduced losses can be achieved by reducing the losses in the materials of the rotors andstators of rotating electrical machines, but also by reducing the losses that occur when changing the properties of the source material during cutting and subsequent joining into rotor and stator bundles. Experimental research will focus on optimizing the microstructure and texture of various grades of electrical sheets in order to minimize electromagnetic losses and optimize the conditions for the production of rotor and stator bundles by cutting and subsequent joining. The optimization of the conditions of joining electrical sheets of various chemical and microstructural concepts will be the expected output of the project. The magnetic properties of the joined electrical sheet cut-outs will be compared with the magnetic properties of the lamellas produced by electrospark cutting. |

Innovative approaches willbe applied in the restoration of functional parts of molds for high-pressure die casting of aluminum alloys. Laserweld overlaying technology will be used for the formation of restoration layers in order to significantly reduce thenegative impact of the introduced heat on the quality of sub-weld layers. Newly designed additional materialsbased on Co, Ni, Fe with the presence of dispersed abrasion-resistant precipitates will be used. Additionalmaterials for laser welding will be used in the form of wires made of Uddeholm Dievar and Maraging. For bettervariability of the chemical composition, powder additives based on Fe with the addition of B, Ti, Nb, Mo, V and Wwill also be used to create weld overlays. The optimal method of heat treatment of weld overlays will be proposed.Research will further focus on microtexturing the surface of molded parts by low-energy laser radiation usinginnovative engraving surface treatment methods (LBT and EBT) in order to ensure a smooth distribution of theseparating agent on the mold surface. Experimental work will be focused on modifying the microgeometry of thesurface of new and renovated shaped parts of molds so that in the phase of "run-in of the mold" a compact layer ofthe separating agent is created to increase the technological life of molds. PVD and PE-CVD technologies will beused for this purpose. |

| Annotation: | Nowadays, there is a characteristic continual pressure on the emission reduction produced by the cars. Onepossible way to reduce the amount of emissions produced by the automobiles is the reduction of the bodyweight. The weight of the automobile could be reduced through the hybrid car body, which consists of differentmaterials based on the light alloys, composite materials and high-strength steel sheets. Solutions related to suchhybrid car body designs must be addressed in to the forming, but also to the joining of the individual parts ofsuch multi-material conception. The aim of the project is the optimization of the forming conditions of aluminiumalloy sheets and high-strength steel sheets to increase the process efficiency. The appropriate joining techniquewill be proposed based on the results of the analyses of the stress-strain states of the formed parts. Acomparison of strength and load-bearing capacity of the joints after different intensity of deformation and stressstrainstates will be the assumed result. Effective and innovative methods of joining of aluminium and highstrengthsteel sheets after different intensity of deformation and stress-strain states will be assessed. The resultsobtained from the optimization of the joining process of the materials made of ferrous and non-ferrous metals willallow the strength of joints to be increased. |
