Pletnev V. Increasing the Reliability and Safety of Technological Automobiles Operations

In the thesis there was solved the actual scientific task aimed at increasing the reliability and safety of opration of the technological automobile transport of a large engineering enterprise by improving its traction-speed performance properties, maneuverability, stability, control using the method of partial accelerations. The method of multiaxial automobile stability estimation in the traction and braking mode and diagnosing its technical condition is developed. The results can be used to ensure the safety of multiaxial vehicles in conditions of hreducer enterprises and their service stations. The method of estimating the technical condition and reliability of automobile and automobile trains brake control is developed, which will make it possible tu assess the likelihood of failure in brake control in the presence of both efficient and failes parts. The theoretical evaluation of stability and controllability of multilink multiaxial automobile trains according tu the criterion of the natural frequency of vibrations in the road plane is conducted. It has been established that at correlation of the total side tire stiffeness the frequencies of the investigated vehicle oscillations are outside the danger zone > 0.7 Hz at any values. Stability and control of the investigated trailing link is provided at > 0.7 Hz.
