“…The cited work does not define the nature of dissipative forces and their impact on oscillations, which is a prerequisite for ensuring a stable resonance movement regime. This is noted by the authors of work [5]. They believe that further studies must account for the dissipation that is introduced into the system.…”

“…The disadvantage of the proposed solution is a complex design that reduces the reliability of its operation. Article [5] discusses the theory of oscillatory normal regimes and its applicability to general mechanical systems, including a resonance mode. Efforts to generalize modal analysis for nonlinear cases were considered.…”

“…Another issue in solving the task is the difficulty of choosing the most rational option according to the results of research (both full-scale and estimation), especially those on the complex working processes of vehicle movement. The consequence of this situation is studying the working processes only in the suspensions of one-mass objects; a characteristic example of this approach is work [12].…”

Decision-making regarding the application of any new structure at the design stage requires in practice that it should be compared with the existing one by many indicators. A special feature of the new design of hydropneumatic suspension is the existence of movable connections (screw and splined) as parts of the hydropneumatic element. The presence of structural friction in movable connections requires, in particular, an assessment of the impact of this friction on the process of oscillations when moving through crossed terrain based on comparative analysis. The comprehensive estimate chosen for comparison includes operational properties in terms of ergonomics (smooth movement) and adhesion to the support surface (effort in the contact of wheels with the support surface). The results of a theoretical study involving a vehicle with parameters (weight, dimensions) close to armored personnel carriers BTR70, BTR80, but with hydropneumatic suspensions, demonstrated that when driving on crossed terrain with speeds up to 65 km/h there is a significant reserve in terms of ergonomics. Regardless of the presence (absence) of structural friction, at friction coefficients of up to 0.085. When moving on the surface with large irregularities, the reserve for the maximum allowable (3 g) acceleration in a driver seat is 4.708 times (there is no structural friction) and 3.768 times (structural friction is present). When moving on the surface with small irregularities, the reserve for the maximum permissible (0.5 g) acceleration in a driver seat is 2.093 times (there is no structural friction) and 2.616 times (structural friction is present). Under the most dangerous modes of movement (at the highest speeds) when driving over small irregularities, the presence of structural friction has a positive effect both in terms of ergonomics and stability. Thus, when driving at a speed of 65.679 km/h, the minimum clutch margin is 1.4 times greater, and the acceleration is 1.249 times smaller

The main purpose of laboratory tests is to obtain experimental data for the development of mathematical models of the functioning of silent blocks of car suspension to develop a method of diagnosing. The object of the study is the process of functioning of the silent block of the car suspension. Methods. The tests were performed in the research laboratory of the Department cars VSGUTU. We used a stand that implements the mode of static and dynamic loading. The frequency range of the lever with the tested silent blocks was set from 0 to 1.67 Hz. During the tests, silent blocks with different technical conditions, both new and from the failure flow of vehicles in operation, were checked. Results. Power characteristics of silent blocks of the car in a dynamic mode are received. Conclusion. The developed method of diagnosis based on the obtained experimental data will objectively determine the technical condition of silent blocks of the car suspension. Also, the application of the method in practice will significantly reduce the complexity of diagnostic work.
