Damping in drivetrains and suspensions of tracked tractors

During operation, parts of the main components and subsystems of tractors are under dynamic loads. Parts of drivetrain and suspension are subject to especially intense dynamic loads. Reducing the level of dynamic loading of parts of drivetrain and suspension is ensured through the use of elastic and damping elements in designs of the machines. In this case, it is necessary to know how different types of damping affect the reduction of the load of parts under cyclic loads and which methods for determining the damping parameters of materials and structural elements have been proposed to date. The development of active damping devices, the elastic-dissipative properties of which adaptively change depending on the nature of dynamic influences is a relevant technical task; in accordance with this, the paper provides a description of the technical solution of such an adaptive damper proposed by the authors. The study was carried out by a calculation method based on the basic principles of the mechanics of materials and the theory of vibrations. Based on the analysis, recommendations were made for the selection of dampers for use in tractor suspensions, and a technical solution for an elastic damping device was proposed. The practical value of the study lies in the possibility of using the proposed recommendations for choosing the designs and characteristics of elastic damping devices for drivetrain and suspension of tracked tractors.
