The subject of improving the competitiveness and efficiency of railway rolling stock is highly demanded as the railway transport consider the nerve of the goods transport in the hole word. One of the requirements to develop the railway transport related to the continuous improvement of existing materials and find a new material which would satisfy such conflicting requirements as relia-bility, sustainability, producibility and the manufacturing process automation possibility. The researches show that use of polymer composite materials (PCM) in the production of both passenger and freight railway rolling stock, provides lightweight, improves its performance, increases durability and reduces operating costs.
This paper presents a new technology of continuous measurement and recording of forces in wheel/rail contact by measuring strains in two rail cross-sections, which allows increasing the measurement accuracy. The method for processing the measurement data is proposed with a variable scale between strains and force, depending on the instantaneous position of the wheel with respect to a span between sleepers. The gage characteristics obtained by rolling a wheel over the rail between two sleepers are approximated by using Fourier series abilities and used for the assessment of wheel/rail forces. By using the suggested technology, the amount of information obtained increased 2 times.
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.
