The test run was performed as described in the work of Czarnuch et al [16]. The data were collected in the form of time signals from the sensors installed on the vehicle when the unloaded semi-trailer, moving on one axle, was crossing over the obstacle at different speeds.…”

Road simulators enable accelerated durability tests under similar-to-real road conditions. However, the road simulator itself generates the signals with the appropriate strength and amplitude that is adequate to the response registered by the sensors during the real run. Therefore, there is a need for verification of the validity of the representation of vehicle runs on a road simulator in terms of the shape of the generated profile and possible sources of uncertainty. The tests in this study were carried out for a multi-axle vehicle passing an obstacle of known shape. Various signals were registered while the vehicle was passing over the obstacle. The MTS (System Corporation) road simulator’s response to the signal given by the obstacle was then checked. The results showed a 99% correlation between the simulation and the road test results. A numerical model of the vehicle was developed to verify the quality of representation of the real conditions by the road simulator, especially in terms of forces resulting from the road profile. Interestingly, the input signal generated by the road simulator provided a very good accuracy of the vehicle response, as tested with use of the numerical model.

“…Special test tracks or mechatronic stations are used as simulators. Czarnuch et al [27] presented the use of the MTS 320 road simulator station for accelerated durability tests of a truck semi-trailer. The authors pay special attention to reproduce the actual conditions and also to determine the duration of such tests, confirming the correlation between reality and simulation.…”

The use of road simulators in vehicle durability tests enables a significant reduction in time related to the implementation of a new product. However, there is still a need to improve the methods of these tests in order to obtain a full correlation between the time of the tests on the simulator with respect to the mileage of the vehicle in real road conditions. The aim of this work is a validation and improvement of the durability testing method for large-sized vehicles. Comparative tests of shock absorbers dismantled from semi-trailers with different mileage and shock absorbers dismantled from semi-trailers after durability tests conducted at the MTS test bench are presented. The relationship between the maximum damping force and the displacement speed of the shock absorber piston was examined. Additionally, the influence of the shock absorber temperature on the damping force was analyzed. As a result of the tests, the dynamic characteristics of the shock absorbers were determined and the relationship between the maximum damping force and the mileage of the trailers was determined. It was found that the load on the trailers during their operation has a significant impact on the change in the characteristics of the shock absorbers. What is new in this publication is the validation of the methodology for conducting durability tests previously proposed by the authors based on the selected component, which is the shock absorber. The authors have not yet encountered in the literature any attempt to validate the methodology for conducting durability tests for large-sized vehicles.

The ability to assess the risks of the functional safety of railway tracks allows harmonizing characteristics of track elements under certain operating conditions under certain maintenance for the efficient use of the track structure throughout its life cycle. The concept of detailing conditions of the interaction of the rolling stock and railway track was used for the productive solution of tasks of infrastructure functional safety assessment. The paper formed an approach to the analytical solution of determination problems of deformability parameters over time using the elastic waves theory. The formation method of interconnections between the technical and economic aspects of the operation of railway infrastructure was proposed. The criteria of deformability work and intensity of use were utilized for the effective use of the track structure through its life cycle. The results of calculations are presented to assess changes in the deformability behaviour of the track elements and structure when the force and speed parameters of the operating conditions change, as well as the algorithm of the method for estimating the operation deformability of the railway track. Thus, the proposed approach can be adapted to optimize objects by railway functional safety assessment at the stage of object operation simulation.
