“…This section contains results of numerical analyses of the designed pedestal structure. Strength analyses have been carried out in the ANSYS software package, which is one of the most widely used software for numerical analysis of technical elements and systems based on the finite element method [8][9][10]. These analyses serve as a decisive criterion of the pedestal design.…”

Skidders represent an important part of the forestry. They allow to perform timber harvesting in difficult conditions of forests in an effective way. In the Slovak republic, only one company currently produces several types of articulated steering skidders differing by the dimensions, operating weight, engine power etc., which are well-known and used in the region of central and Eastern Europe for many years. These products are exposed to the strong competition from other world producers. In comparison with earlier technical solution of skidders, which have used winches for pulling trees to a landing, skidders are recently most often equipped with a hydraulic grapple, which is controlled by an operator directly from a skidder cabin. Thus, the operator has not to get off the cabin in order to drag the cable to the logs and hook them up. Hence, the hydraulic grapple improves the user comfort of a skidder, mainly in bad weather conditions. Therefore, every skidder is currently required to allow mounting the hydraulic grapple. The content of this article is focused on presentation of the design of a pedestal, which is intended to be mounted on an articulated steering skidder. The pedestal is the structural unit of the smallest type of the skidders produced in the Slovak Republic. The designed pedestal will be mounted in the rear part of the skidder. Winches are located under it. Therefore, the pedestal has to be clapper for better access to winches during maintenance and repair processes. As the pedestal will be loaded by various types of loads resulting from its fundamentals in the real operating conditions, its structure has to be designed precisely. The article contains a CAD model of the pedestal. Based on the calculated forces, which will act on it during a real operation, strength analyses are carried out.

“…In its operation, the coal-transporting flat carriage experiences various static and dynamic loads on its structure, due to the condition of the railroad that could be straight, turns left or right, go uphill and downhill; and at the time of stopping, when there is braking, experiencing compression to the structure due to the series of carriages from the front-rear. The impact of these operational loading conditions could affect the structure/ construction of the carriage [13][14][15][16] . The Indoneian regulation of the Minister for Transportation number PM 17 of 2011 states that every carriage operated must have the structural strength and durability in receiving operational loading 17) .…”

A flat carriage is a vehicle type without a body and a roof for transporting goods, designed to meet the needs of heavy goods. Several conceptions are elaborated, with respect to capacity of 57-ton recommended to 2x20 feet containers. The aim of the paper follows determining the strength and durability of the flat carriage under operational loading at accordance with the required criteria and using a fatigue limit diagram approach based on the Soderberg method. This research was conducted with static and dynamic tests. The sections for 50 strain gauges were indicated based on data from to the finite element method. The results showed that in the case of vertical static loading, the maximum stress on the flat carriage structure occurred at full vertical load (50,050 kg) in the end centre sill area, at single measuring location no. 24, with a value of 59.8 MPa, and the results of the static test were still below the allowable stress of the material at 243.8 MPa. Meanwhile, at the dynamic loading conditions, the greatest stress occurred at single measuring location no. 24 with mean stress value of 59.7 MPa, stress amplitude was 17.8 MPa, and at single measuring location no. 23 with mean and stress amplitude values of 59.6 MPa and 34.4 MPa, respectively. The results of the analysis showed that the mean stress value (σmean) and amplitude stress value (σamp) were still below the fatigue limit curve of the Soderberg diagram. From the results of this research, it was concluded that the 57-ton flat carriage prototype construction/structure, under static and dynamic loads, can be manufactured as many as operational needed.

The article presents the results of research into the strength of the hatch covers of general-purpose open wagons. It was detected that strength of the standard hatch covers is not provided in operational loading diagrams. Therefore, new designs of the hatch covers for open wagons were proposed. The results of the strength calculation, implemented with the finite element method, make it possible to conclude that at basic and additional operational loading diagrams the strength values for proposed designs of hatch covers do not exceed the admissible values. The research conducted can contribute to a higher strength of the carrying structures of the bodies of general-purpose open wagons in operation, thus, guaranteeing a higher operational efficiency of the rail transport.
