Abstract
AbstractIn modern mechanical engineering, there are a large number of shock absorber designs with the ability to adjust the damping characteristics, which are called relaxation. At present, hydraulic piston shock absorbers with the translational motion of the movable element relative to the body are used as dissipation devices in suspensions. These shock absorbers realize the performance of the throttle-valve type only, which is associated with the functionality of these devices, depending on design constraints. In this work, the synthesis of fundamentally new relaxation dampers was carried out, the performance of which is not related to the pressure in the working cavity. Their essential difference is the presence of a mechanical control loop in the structure, which determines a close relationship between the operating characteristics of the shock absorber and the amount of movement of its moving element relative to the body. In the synthesis process, the approbation of the corresponding methodology was carried out, built based on modeling technical systems with modified kinematic graphs. The synthesis results are presented in the form of two constructive implemented samples. A comparative analysis of the obtained samples was carried out, and their main operational characteristics were determined.KeywordsGraph theoryKinematic graphsShock absorberPerformance characteristicsMechanical control
