Subject of the inquiry: the protective carcass of a cabin of universal wheel tractor-cultivator. Aim of the inquiry: design procedure working out on durability and the substantiation of strength parameters of the carcass of cabin of tractor of a class 1.4. Methods of inquiry: Researches were spent by methods of mathematical and experimental modeling of deflections of elements of the bearing carcass of the cabin of the tractor at overturning in quasi-static to statement The results achieved and their novelty: - the mathematical model of calculation of the carcass of the cabin of the tractor on durability is made; - the design procedure of the protective carcass of the cabin of the tractor on durability taking into account process of distribution of a zone of plastic deformation on length and height of cross-section section of elements of the construction of the carcass; - Dependences strength properties of rod elements of the construction of the carcass from the bend and curvature moment. Practical value: the cabin design procedure on the durability is developed, allowing at a design stage and operational development of a design with high degree of reliability to receive demanded strengthening characteristics (the Patent for the computer program № DGU 01583). The multiple analysis of the construction of the cabin of tractor TTZ 80.20 is carried out and the new carcass of the cabin of the tractor (the Patent for utility model № 1'AP 00563) is offered. Degree of embed and economic effectiveness: Results of work are transferred to special design engineering bureau “Tractor” for practical use at carrying out of developmental works on modernization and construction development of new carcass of cabins of tractors. Sphere of usage: automobile construction and tractor construction.
