Volumetric dynamometer units for laboratory and field testing of tillage equipment

Abstract

The search for energy efficient tillage technologies and the creation of more advanced machines while reducing the cost of the final product are one of the priority goals. One step in the development of tillage implements is to develop a theoretical basis. In this case, mathematical or simulation modeling is used, but part of the work carried out in the laboratory and in the field is an integral part of the research structure. Of great importance in testing forestry equipment are dynamometer methods, which consist in measuring the forces transmitted from the engine to the machine or acting on the working bodies and parts of the machines. This is especially true for forest implements that interact not only directly with soils, but also with roots, branches, stumps and other components of forest soils. The article is presented in the form of an analysis of the structures of dynamometric installations used to conduct research on tillage equipment. Also given are the designs of installations used for research of combined machines with active working bodies, such as a forest fire engine. Particular attention is paid to structures for volumetric dynamometry (2D and 3D).
