The article presents the results of theoretical and, most importantly, experimental studies of some properties of steel-fiber-reinforcedconcrete reinforced with dispersed reinforcement from industrial wastes, namely, ITEX steel wire fiber from SPA INNOTECH from spent steel ropes, a large number of which are used as raw materials for fiber production, has accumulated in the region with the mining industry (East Kazakhstan region). The result of the research was indicators of tensile strength of fiber-reinforced concrete during bending of samples, characteristics of crack resistance, and impact strength indicators of fiber-reinforced concrete reinforced with fiber from industrial waste. Knowing and demonstrating these characteristics will make it possible to more effectively ensure the possibility of selling a new product on the building materials market. This publication has been carried out as part of the sub-project Technology for Manufacturing Fiber from Technogenic Wastes, funded by the Government of the Republic of Kazakhstan and the World Bank, Project for Stimulating Productive Innovations.

“…Each module of the stand consists of a frame (1) with bores (2), guides (3) for vertical movement of the frame, fixed stationary. On each frame is mounted a support disc (4) with an axis (5) resting on a tapered bearing (6). The drive of rotation of the support disc is made in the form of an electric motor (motor-reducer) (7) placed outside the contour of the frame and mounted balanced, flexible gear (belt) transmission (8), the leading sprocket (9) of which is placed on the shaft (10) of the electric motor, the driven (11) -on the axis (5) of the drive of rotation of the support disc.…”

The authors have developed and are investigating the original design of a stand for testing the braking properties and suspension of wheeled vehicles, which provides the shape of the tyre contact spot with the support surface closest to real road conditions. The originality of the stand was confirmed by the decision to grant a patent for an invention of the Russian Federation. The advantages of implementing the proposed stand design, as well as disadvantages and ways to overcome them, are considered.

“…The data obtained during the experiments were checked for convergence with the results of theoretical calculations [7][8][9][10][11][12]. The magnitude of the discrepancy between the theoretical and experimental values averaged 19-27 % for a runner without anti-skid means and 7-10 % for a runner with a pendulum.…”

“…Due to the fact that the rotation center of the carrier of the vibration exciter is asymmetrically shifted in one direction, the maximum impulse of the driving force of the vibration exciter is shifted in the same direction, which can be 3-5 times larger than the pulse directed in the other direction [5][6][7].…”

In the drives of the working bodies of ice breaking, road, construction and other technological machines the use of asymmetric planetary vibration exciters becomes promising. Where rotation carrier axis of the inertial runner is shifted relative to the treadmill center. Vibro-exciters of this type as a result of the joint action of the centrifugal and Coriolis forces on the inertial slider provide a significant increase in the integral value of the directional driving force. The momentum is proportional to the eccentricity of the carrier and directed towards the specified displacement of the carrier axis. The article presents the original mathematical and graphical dependencies characterizing the workflow of these vibration exciters and confirming their effectiveness.
