The article presents a calculation procedure for determining the maximum permissible load on the welded structure of the transport carriage. During the transport carriages operation inside the production hall there was no breakage of the welding joints. The use of carriages outside the hall and with an uneven surface began to create cracks and fractures in the weld joints. The values of vertical accelerations that were generated by running on uneven surfaces were determined by experimental measurement. To avoid cracks in welded joints, the maximum permissible load value of the transport carriage was subsequently determined by calculation using FEM. This work was supported by the Slovak Research and Development Agency under the contract No. APVV-14-0096. This publication is the result of the project implementation: Development of two types of freight wagon with bogies for non-standard wheelbase or track wheelset, complying with the criteria for interoperability, environmental issues, safety and reliability ITMS: 26220220070 supported by the Operational Programme Research and development funded by the ERDF.
