The Influence Of The Novoangrensk Tpp Ash On The Structure Formation Of Cement Stone, V.M. Tsoy, F.F. Karimova, N.R. Muhammadiev May 2021

The Influence Of The Novoangrensk Tpp Ash On The Structure Formation Of Cement Stone, V.M. Tsoy, F.F. Karimova, N.R. Muhammadiev

The Scientific Journal of Vehicles and Roads

This article presents the results of experimental studies to study the effect of fly ash of the Novoangrenskaya TPP on the properties of filled cement stone. In particular, the analysis of microscopic studies of filled cement stone from fly ash was carried out, which made it possible to draw a conclusion about the increase in the strength of the cement composite in connection with the strengthening of its structure.


Numerical Studies On The Model Of The Modernized Unit Of The Cradle Suspension Of The Vl-80s Electric Carrier While Moving In Curves, G.A. Khromova, I.S. Kamalov, M.A. Маkhаmаdаlieva May 2021

Numerical Studies On The Model Of The Modernized Unit Of The Cradle Suspension Of The Vl-80s Electric Carrier While Moving In Curves, G.A. Khromova, I.S. Kamalov, M.A. Маkhаmаdаlieva

The Scientific Journal of Vehicles and Roads

The article presents the results of numerical studies of the stress-strain state of elastic rods of variable cross-section and mass, taking into account the elastic fixing of the ends for the cradle suspension unit of the electric locomotive (for example, the VL-80s electric locomotive) with a harmonic external influence that occurs when the electric locomotive moves along a path with periodic irregularities on straight sections and in curves, an algorithm and a program for the MathCAD 15 programming environment were developed.


Method Of Quantitative Research Of Navoi City On The Basis Of Choice Of Traffic Flow, K.Z. Ziyayev May 2021

Method Of Quantitative Research Of Navoi City On The Basis Of Choice Of Traffic Flow, K.Z. Ziyayev

The Scientific Journal of Vehicles and Roads

Due to the rapid growth in the indicators of population mobility, the demand for transport Services is increasing. The increase in traffic at various levels in the city streets is causing problems with harmful effects on the environment, increasing demand for energy resources. This determines the importance of increasing the efficiency of the use of existing transport infrastructure through the planning and modeling of transport. The article covers the method of determining the actual traffic flow in the cross-section of existing types of transport (in the example of the city of Navoi). Bunda said that urban traffic flow was carried …


Analysis Of Magnetic Chains Of Transformers Exchangers Measuring The Difference In Angle Silences, S.F. Amirov, N.R. Yuldashev May 2021

Analysis Of Magnetic Chains Of Transformers Exchangers Measuring The Difference In Angle Silences, S.F. Amirov, N.R. Yuldashev

The Scientific Journal of Vehicles and Roads

The analysis conducted using the method of equivalent exchange schemes of magnetic chains of transducers, which are new and its closest analogue, working on the transformer principle, measuring the angle silences and their difference, showed that the new design of the transducer has a higher measurement sensitivity compared to its closest analogue, which is, the separation of the excitable magnetic conductor and the measuring instrument into two and the arrangement of the magnetic conductors in the form of an Archimedical spiral, as well as the connection of the measuring instrument sections in a mutual differential scheme, makes it possible to …


Modeling Bus Bunching And Anti-Bunching Control Accounting For Signal Control And Passenger Swapping Behavior, Qi Xin, Rui Fu, Shaowei Yu, Satish V. Ukkusuri, Rui Jiang Apr 2021

Modeling Bus Bunching And Anti-Bunching Control Accounting For Signal Control And Passenger Swapping Behavior, Qi Xin, Rui Fu, Shaowei Yu, Satish V. Ukkusuri, Rui Jiang

Journal of Public Transportation

The conventional bus propagation process has two main shortcomings: one is bus bunching, the other is extra energy consumption by idling at signalized intersection and unexpected speed variation along the route. To overcome these problems simultaneously, an extended bus propagation model and an anti-bunching control are proposed. To extend the time-based bus propagation model, we employ finite state machine and intelligent driver model to establish a spatial-temporal based bus propagation model accounting for bus dynamic motion and passenger swapping behavior between bunching buses. To mitigate bus bunching and improve bus fuel economy in a cyber-traffic environment, an anticipated average speed …
