    An improved methodological approach to assessing the vibration levels of passengers of a mobile car during its virtual tests on mathematical models in the design problem of choosing the parameters of the general layout and suspension of electric bus 6K2 is considered. When considering human vibrations in a machine, it is advisable to determine them taking into account the structure of the human body. Harmless vibration levels for different parts of the body are significantly different in amplitude and frequency. Vibration levels affecting a person be determined on the basis of two-mass and four-mass models of the human body, as recomended The International Organization for Standardization ISO. A computational experiment of parametric optimization of the suspension according to the proposed approach and criteria-rules allows you to find the required rational suspension parameters of the machine. The following considerations allow to carry out structural optimization of the layout of the passenger compartment of the electric bus, considering the effect of occupancy of the passenger compartment and schemes for random placement of passengers across the passenger compartment.

    The article presents an analysis of the kinematics, working parameters and modes of operation of swing-type digging share with elliptical profile cutting edge, and opportunities for rational operating regime adjustment of the working body under the conditions of operation. Expressions are derived and an analysis of kinematics, working and regime parameters of the swing-type share with elliptical cutting edge is given.

    The aim of the study was to evaluate the horizontal and vertical force of reversible moldboard plow at various operation depth and speed. A complete randomized block design was used with three replications, the first treatment was tillage depth with three levels 15, 20 25 cm and the second treatment was the forward speed with two levels 3.9, 6.3 km·h-1. The result showed that both forces were increased as increased of tillage depth and speed, however, the operation depth was more effective than speed, on the other hand, the horizontal force was more affected than vertical force by increasing both of depth and speed.
