Simulation model of the automobile braking system performance taking into account not only the wheel, brake pads, brake drum dynamics but the dynamics of the hydraulic brake system: the main hydraulic cylinder, the brake gear hydraulic cylinders has been presented. Effect of changing parameters of the braking system elements on the braking distance of the automobile has been considered. Road users’ safety relies heavily on effectiveness of vehicle braking system. Thus, braking system design is essential when designing a new vehicle. Modeling of the functionality of the designed system is one of the most important phases of design. Time and material expenses for imitational modeling are always less than actually producing models and conducting experiments on them. Experiments should prove theoretical abstracts stated while modeling. Thus, the imitational model should be well designed and adequate. Imitational model allows efficient operation of brake system with different system of control.
One of the main tasks of raising the technical level of highways, safety and environmental performance is timely and targeted collection and removal of water from the surface of roads and subsequent cleaning of pollution. In modern technologies of water purification processes of water filtering and filtering materials occupy the dominant position. The progressive environmental degradation of water bodies requires constant updating of filter elements, which include higher technological and environmental requirements. The new generation of modern filter materials include zeolites. In order to use the sorbents for the removal of oil, they are to be hydrophobic and, at the same time, absorbing oil well. As a result of comparative evaluation of sorption purification of waste water from the surface of roads, using zeolite and gravel mixture there was determined the efficiency of using alternative materials. The introduction of new methods of treatment using natural zeolites solves the problem of raising the technical level of highways, traffic safety and environmental performance.
The article analyses the volume of passenger traffic from 1990 to 2019 for land, water and air transport. From
the materials obtained and the experience of the networks of European and world high-speed railways, goals are set.
High-speed lines designed exclusively for passenger traffic. This moment plays an important role in reducing the cost
of construction, increasing the market and economic profitability. According to the data from the State Statistics Service
of Ukraine, it is possible to calculate the passenger flow based on the known parameters for 2020–2032 in the direction
of Kiev–Lviv. The design of high-speed lines should meet general requirements aimed at satisfying the basic
characteristics of a high-speed railway system, which works in conjunction with the European High-Speed Railway
network. The compatibility of the parameters of high-speed lines with the parameters of traditional lines is part of the
operational requirements for the gradual introduction of a network of high-speed railways. Possible scenarios to achieve
the required compatibility should cover all subsystems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
