“…The simplified mathematical model describing the motion of the compacting plate and the impact body is derived (see Eq. (1)(2)(3)(4)). The 3D model of the vibratory plate compactor designed in SolidWorks software and the numerical modeling of the oscillatory system motion carried out in Mathematica software allowed for obtaining the time dependencies of the compactor horizontal displacement 𝑥 𝑡 and velocity 𝑥 𝑡 (see Fig.…”

“…The technique of design optimization of the self-propelled plate compactor equipped by the eccentric (inertial) vibration exciter is considered in [2]. The paper [3] is devoted to modeling the operation of the three-mass stacker vibration plate and testing the compaction quality. In [4], the authors developed a nonlinear dynamic model describing the "asphalt mixture -vibratory screed" interaction and studied the efficiency of the compaction process.…”

The paper is aimed at studying the motion conditions of the vibratory compacting machine equipped with the crank excitation mechanism characterized by the changeable geometrical parameters. Unlike numerous scientific publications devoted to similar subject, the novelty of the present research consists in the improved design of the vibro-impact plate compactor and the developed mathematical model describing the motion conditions of the compactor's oscillatory system. It is proposed to use the crank mechanism to excite the oscillations of the impact body acting upon the frame of the compacting plate at a certain angle to the surface being compacted. The main idea of this improvement is to provide the self-propelling locomotion conditions of the compactor and to reduce the pushing force that must be applied by the operator. The research results obtained by means of the numerical modeling in Mathematica software describe the dynamic behavior of the compactor's oscillatory system under different geometrical parameters of the crank excitation mechanism (crank eccentricity, impact gap, etc.). The material of the paper can be of significant practical interest for the designers and engineers dealing with the development of new vibratory compactors and the improvement of compacting technologies.

Introduction. Impact-vibration machines, which perform soil compaction with periodic removal of the working body from the ground, are the most common for mechanization of soil compaction in road construction: self-propelled non-reversible and reversible vibratory plates, vibratory rammers, mounted excavator vibratory plates, trench vibratory rollers and soil vibratory rollers. It is necessary to analyze the main technical characteristics of impactvibration machines of different types in order to assess the possibility of developing a mathematical model of soil compaction, combining several types of impact-vibration machines at once.Materials and methods. The technical characteristics of different types of impact-vibration machines for the analysis: 342 models of non-reversible self-propelled vibratory plates; 312 models of reversible self-propelled vibratory plates; 311 models of vibratory ground rollers; 63 models of mounted vibratory plates for excavators; 24 models of vibratory rammers and 21 models of trench vibratory rollers are used. The machine mass (for vibratory plates of different types) or the mass per compaction module (for vibratory rollers of different types) was taken as a main parameter.Results. The graphical dependencies have been obtained. They illustrate that for the given types of shock-vibration machines the excitation force, relative excitation force and oscillation frequency are located on mutually contiguous and continuing parts of curves. This is a common pattern: as the mass of the machine increases, the excitation force increases, but the relative excitation force and frequency of oscillation decrease. Vibratory rammers are out of this general pattern, because at comparable weight they have significantly lower frequency of oscillation (9...12 Hz) and high amplitude (50...75 mm). Also, the mounted excavator vibratory plates stand out from the general pattern, having a smaller range of vibration frequencies for machines of similar weight, moreover, they perform soil compaction positionally, and not in the process of movement at a certain speed, as other impact-vibration machines.Discussion and conclusions. The common pattern of changes in the main technical characteristics of selfpropelled non-reversible and reversible vibratory plates, trench rollers and soil vibratory rollers at close nominal amplitude of their vibrations gives grounds for the development of a unified theoretical description of the interaction of the working bodies of these types of machines with the compacted soil and a common method of calculating the influence of technical characteristics and operating modes of these machines on the results of soil compaction.
