CONSIDERATIONS ON STATIC NONLINEAR ANALYSIS OF COUPLING DEVICES - NONLINEAR CURVE STRESSES

Coupling devices are the elements ensuring the connection between the power source (tractor) and the towed machine, which must be checked in terms of their safety on the public roads by means of different methods. One of these methods is represented by non-linear static analysis through nonlinear curve stresses, which can in some cases replace verification by endurance testing. The paper presents such an analysis as well as the results obtained from this analysis

TECHNICAL CONSIDERATIONS REGARDING TO HARVESTING PATATOES AND CARROTS EQUIPMENT

Potatoes and carrots are two plants of great importance in human life. The two vegetables are grown on increasingly large surfaces, which have led to the need to mechanize their planting, maintenance and harvesting technologies. In the continuation of the material, we will find some types of potato, carrot and root crops for both small surfaces and large and very large surfaces.The harvesting technologies of the two plants are similar, so for the types of potato or carrot picking machines (beet, onions, etc.) and leaves the crop on the furrow, the same type of machine can be used. The diversity of these harvesters is very high from one-row or two-row universal trailed to self-propelled harvesters specialized in harvesting a particular crop, which, through a single pass, can do all of the following: dislocation the harvesting material, sorting, collecting and loading them directly into containers, transport trailers or in their own hoppers with automatic downloading capabilities
