This paper presents the development of a unique method for experimental determination wheel–rail contact forces and point position by using instrumented wheelset (IWS). Solutions key problems in IWS are proposed, such as optimal locations, layout, number way connecting strain gauges well an inverse identification algorithm (IIA). The base solution these is wheel model results FEM calculations, while IIA based on blind source separation independent component analysis. In first phase,...
The topic of this paper is the usage algorithm marine predator (MPA) in optimization suspension rail vehicles with coil springs. aim to reduce mass set springs as main parts suspension. optimized must satisfy appropriate conditions related characteristics, achieving required operation quality and running security observed vehicle. Starting from bi-linear characteristic analytical description its parameters, an problem formulated. It composed six objective function 16 constraints (eight for...
Railway transport has a very important role in economy of every country. The efficiency railway depends both on the quality organization and technical reliability rolling stock. During operation freight wagons last years, large number breaks suspension system elements have been noticed. This feature is especially reported at four-axle double wagon for coal (designated Fbd) three-axle cars DDam). Frequent reduce some cases cause derailment lead to economic losses. In this paper, causes...
The paper presents the design of a specific type instrumented wheelset intended for continuous measuring lateral and vertical wheel-rail interaction forces , in accordance with regulations EN 14363 UIC 518.The platform is standard heavy BA314 an axle-load 25 tons.The key problems smart instrumentalization are solved by use wheel's numerical FEM model, which provides significant cost reduction initial stage development wheelset.The main goal to ensure high accuracy.The results calculations...
The paper deals with the analytical identification of critical section axle a freight wagon.The procedure for calculating strength railway axles in accordance European standard EN 13103 is shown.Based on this, method identifying was presented.The goal to find or zone lowest dynamic safety factor.The proposed applied specific example wagon an load 22.5 tons.The obtained results have shown that located transition radius between wheel-seat and middle part axle.The were verified by FEM...
Brake triangles are very important parts of the braking system railway vehicles that can significantly affect safety and security on railway. In accordance with international standard UIC 833, requirements for manufacturers brake strict require supplier to provide proof quality triangles. Therefore, must appropriate evidence production in above-mentioned standard. The paper presents basic 833 development test stand static testing Serbian company Tehnoliv Komerc from Velika Plana. This...
The wheel-rail contact forces are the main influential parameters and indicators of quality dynamic behaviour railway vehicles. Their exact determination has a great practical importance in development testing Past experiences have shown that best way for these is experimental or measurement can be stationary (track side systems) continuous (vehicle systems). When it comes to vehicle systems, which obligatory many cases certification vehicles according international standards, there no...
The paper deals with the usage of grey wolf optimiser (GWO) in optimal design leaf springs railway vehicles. main goal is minimisation mass spring, retention required characteristics suspension system. Based on exposed analytical model and requirements for system, an optimisation developed. developed GWO are applied spring 4-axled freight wagon axle load 200 kN. obtained results have shown that proposed provide significant reduction about 46.7%, relation to conventional method. In addition,...
The failure of axle-bearing is one the most common causes derailments railway vehicles which are usually accompanied by huge material damage and human casualties. Modern railways working intensively on development implementation appropriate systems for early detection axlebearing malfunctions, typically manifested increasing its temperature. approach based use wayside or checkpoints located in certain places along track. There also an innovative that involves using system continuous...
