Property optimization of suspension of caterpillar tractor

There the study objects are the cushioning systems of caterpillar tractors, which contain the non-linear elasto-dissipative links at the operation on the different soil background and under the different operating conditions. The paper purpose is to create the program set for the scientific and designing studies of cushioning systems, which allow to solve the creation problems of agricultural caterpillar vehicles on the high engineering level during the shortest periods. The new technique, the new mathematical model and the new program set for the determination of motion fairness indicators of vehicle-tractor assembly and for the property optimization of its cushioning systems with view to the improvement of motion fairness have been developed. The properties of cushioning systems of T-5 outlook tractor, which allow to have the vibration level on the driver's seat not more the permissible level according to the international standard, have been determined and have been recommended by the State Special Design Office at the Volgograd Tractor Works PO. The cushioning system properties to be recommended have been used in the suspension of T-5 outlook tractor, the program set has been introduced in the educational process of Volgograd Polytechnical Institute according to 1502 "Motor Vehicles and Tractor Making". The introduction efficiency: the rise of motion fairness, the decrease of designing periods of cushioning systems and the shortening of periods of natural tests of tractorsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
