The article presents the results of experimental research on creating the mobile continuous earthmoving machinery. Methods for performing field experimental studies and measuring equipment used are described. The article shows the data of experimental research, their analysis, the determination of physical nature of changes in external load characteristics of the machinery operating equipment. The conducted experimental studies of modern mobile earthmoving machinery enabled to establish its technical capabilities, the characteristics of the power load of the operating equipment when developing the soil. It also enabled to determine the ways and directions for modernizing the operating equipment of machinery. One of the ways is to optimize technological combination of soil cutting, displacement of the developed soil to the unloading area and unloading of the actuator. The research performed and the results obtained have enabled to experimentally confirm the effectiveness of the technical proposals to create the design of the chain and bar actuators with impulse soil unloading intensifiers for trenchers implemented in the industry.

“…Since the Simpack software is a universal MBS software intended for modelling road as well as rail vehicles, in the database several contact models are available. Various contact models provide information about calculated quantities, which are distributed in a contact patch [21,28]. Despite the fact that the problem of the contact of a wheel on a road or rail seems to be similar, many different models are developed [22,23,31] regarding to calculation of the contact problem.…”

Vibrational properties of road vehicile are ussually evaluated according to two criterions, i. e. in terms of comfort for passengers and in terms of drive safety and roadway load. The topic of this article is focused on evaluation of passenger's ride comfort of a three-wheeled road vehicle. From the ride comfort point of view vertical vibration is decisive. Vertical vibration is given by obtained accelerations in given position on an assessed vehicle when it is driving on a road with various surface qualities within required time intervals. In the vehicle's design phase its vibrational properties are detected and evaluated by means of simulation computations on a virtual model. In our research we have assessed ride comfort of the three-wheeled vehicle, which were designed in our workplace. For purposes of dynamic analyses we have used multibody approach using Simpack software. The objective of this work is verification of the relevance of the current mounted suspension system for the greater driving speeds range of the three-wheeled vehicle and for different road qualities.

“…the stability loss of the metrobus. It was shown in [17,18] that the critical speed of a road train is significantly influenced by its design parameters. Therefore, further by means of the solution of the system of differential equations of the metrobus movement, the influence of pressure in the tires of the wheels of trailers axles, the location of the trailers center of mass, distances from the center of mass of the bus с and the trailer с1 to the coupling points, the base of trailers and the mass of the bus and trailers on the magnitude of the critical speed of movement were analysed.…”

The peculiarities of organization and perspectives of mass passenger transportation in the city and beyond are considered with the use of "Bus Rapid Transport" (BRT) or Metrobus. Different aspects of study of motor vehicles (MV) controllability and stability are analyzed. It is substantiated that it is sufficient to consider the potential stability of the MV itself, in order to guarantee the stability of the "driver MV" system with a large reserve. A mathematical model of a three-axle bus train consisting of a bus and two trains (metrobus) is developed and the factors influencing the critical speed as the main index of the stability of its movement are determined. It is established that the increase of the critical speed of the metrobus can be achieved by increasing the base of the bus, the first and the second trailer, as well as the mass of the bus and the coefficients of resistance of the drive wheels of the bus driving axle and the trailers axles. At the same time, increasing the distance from the mass center to the bus rear axle, increasing the distance from the mass center to the point of the coupling of the bus with the first trailer, increasing the mass of trailers and the resistance of the resistance of the wheel drive of the bus axis lead to a decrease in the critical speed of the metrobus. This must be taken into account both when designing metrobuses, and when operating them.
