Abstract Paper presents results of works concerned with modernization of freight wagons during their periodic repairs. In this paper, the freight car type 1415 A3 designed for coal and aggregate transport is analyzed. The aim of the research project is to minimize problems occurring during its exploitation. The main idea is to use innovative materials and technologies to repair this type of wagons. The CAD model of analyzed freight wagon is presented. Also results of tests realized on the created laboratory model of the wagon are presented. Measurements of vibrations of the model were carried out using piezoelectric foils in order to verify if it is possible to infer about the state of the system taking into account its dynamical response that occurs as a result of excitation generated during its exploitation.
1 Introduction Railway transport is very important for the development of the modern economy this is why many research works concerning with problems occurring in this way of transport and its development are being carried out all the time. The goal of those works is usually to develop the infrastructure that is used for transport of goods and people, make it more cost-effective, safe, and less burdensome for the environment [1, 17]. Very important are the problems of freight car dynamics during exploitation different driving conditions [5, 8, 18]. In all of those works, the problem of modeling of real object has a strong influence on obtained results and has to be solved using A. Buchacz (✉) ⋅ M. Płaczek ⋅ A.

precise methods [5, 12, 16, 19]. This is why computer-aided methods including finite element method, are used very often [11, 14]. On the other hand, experimental analysis and tests are also very important in order to verify results of calculations and simulations and to carry out the process of used models validation [10, 12]. Presented paper is a part of research works concerning possibilities of freight wagon modernization using new composite materials [2, 3]. The aim is to modernize freight wagons during their renovation. The project is carried out by the consortium that consists of the scientific entity—the Institute of Engineering Processes Automation and Integrated Manufacturing Systems from the Silesian University of Technology and enterprises—DB Schenker and Germaz. The aim of this research project is to modernize the analyzed wagon during its renovation using new materials. Effects that are to be achieved by the modernization are • better corrosion protection of the w
