INTERACTION OF EXCAVATING PART OF RIPPER WITH FROZEN ROCKY SOIL IN STATICALLY-DYNAMIC APPLICATION OF LOAD

There the purpose is to create the effective statically-dynamic ripper for layer-by-layer working of frozen soil with rocky inclusions on the basis of optimum computing criteria which provide for the best effectiveness of operation. The excavating part of Statically-Dynamic Ripper (SDR) has been considered as the physical body for the first time. The implantation of tool into soil has been described both by instantaneous pulse and at the expense of repeat stress waves. The equations which describe the interaction of tool with soil take account of wave behaviour of pulse transfer from the exciter to the tool and from the tool into soil. The procedure of engineering computation of statically-dynamic ripper has been developed. The designs of SDR, which were protected by Inventor's Certificates, have been developed, have been made as the prototypes. The application field of tractors from 100 kN traction class has been expanded for the vehicles of main class. The failure of frozen rocky soils is possible by the rippers on basis of these tractorsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
