“…"Hyperloop is an innovative concept of a new (fifth) mode of transport, also known as a vacuum railway" [3], which consists in moving the vehicle in the form of a hermetically sealed capsule with the transported passengers or cargo in a low-pressure tube [4]. This innovative method of transport, proposed by Musk [5], begins to be more and more often and more widely described in various publications, so that the advantages of HP technology include ecological safety and ecological cleanliness, comfort, independence from atmospheric phenomena, and the possibility of full traffic automation.…”

“…A lot of literature is devoted to aspects of the geometry and motion of the capsule along with technical data such as temperature, pressure, and resistance of the capsule. Kisilowski and Kowalik [4] undertook the analysis of technical problems that solve the dynamics of systems subjected to moving loads. For this purpose, they conducted an analysis using a numerical 3-D model of the guide.…”

You can read about the research on the aerodynamic properties of the HP capsule inside the vacuum tube in this article [13], while about the technical aspects of the cooperation of magnetic elements with the guide placed in the tube in this article [4]. Some capsule design methodologies have received an award for innovation in design concept [14].…”

The innovative concept of the vacuum railwayhigh-speed transportation system has for many years aroused great interest of people dealing with the issues of modern and effective transport systems. Transport scientists and engineers see this technology as a great opportunity for modern societies, at the same time, struggling with many difficult and still unsolved problems. This article presents partial results of the research carried out to assess the feasibility and legitimacy of implementing this technology in Poland. Particular attention was paid to the research methodology for estimating the demand for passenger capsules used for the transport of people in hyperloop (HP) technology. The authors also presented the results of using this methodology to determine the investment outlays for HP capsules intended to handle passenger traffic on selected routes planned in Poland. The authors' contribution is an innovative approach to determining the demand for passenger capsules, the investment outlays, and the maximum capacity depending on parameters such as, for example, the sequence time or travel time of capsules on one of the future HP routes in Poland.

“…Severe shock loads may occur during the passage through the turnout, generating severe damage to the surfaces of the turnout components [33]. Traffic of rail vehicles in regular operation may be considered as a source of influence of high-dynamic loads of cyclic nature, which translates into damages in the form of abrasive and fatigue wear and tear, as well as changes in the shape and dimensions of the outer layer [34][35][36][37][38]. Calculations of dynamic loads and resulting contact and internal stresses enable rational design of railway turnouts and correct selection of material to construct their The mechanical destruction process of the surface layer leads to undesirable changes in the dimensions and shape of the contacting rolling surfaces of the turnout and railroad wheel elements.…”

The operation and maintenance of railroad turnouts for rail vehicle traffic moving at speeds from 200 km/h to 350 km/h significantly differ from the processes of track operation without turnouts, curves, and crossings. Intensive wear of the railroad turnout components (switch blade, retaining rods, rails, and cross-brace) occurs. The movement of a rail vehicle on a switch causes high-dynamic impact, including vertical, normal, and lateral forces. This causes intensive rail and wheel wear. This paper presents the wear of rails and of the needle in a railroad turnout on a straight track. Geometrical irregularities of the track and the generation of vertical and normal forces occurring at the point of contact of the wheel with turnout elements are additionally considered in this study. To analyse the causes of rail wear in turnouts, selected technical–operational parameters were assumed, such as the type of rail vehicle, the type of turnout, and the maximum allowable axle load. The wear process of turnout elements (along its length) and wheel wear is presented. An important element, considering the occurrence of large vertical and normal forces affecting wear and tear, was the adoption of variable track stiffness along the switch. This stiffness is assumed according to the results of measurements on the real track. The wear processes were determined by using the work of Kalker and Chudzikiewicz as a basis. This paper presents results from simulation studies of wear and wear coefficients for different speeds. Wear results were compared with nominal rail and wheel shapes. Finally, conclusions from the tests are formulated.

“…Research on the means of transport do not always regard the existing solutions. For example in [5] a model of a guideway for a Hyperloop capsule has been presented. On the other hand research on the means of transport can also be related to both maintenance and ecology, as for example in [2] where the selected aspects of using electric vehicles with fuel cells has been considered.…”

Simulation of a Motor Vehicle Momentarily Accelerating in Various Road Conditions

In this paper some selected conclusions have been drawn from the simulated maneuver of a vehicle’s momentary acceleration in various road conditions. The aim of this paper was to answer the question whether the random irregularities of the road could decrease the final speed of the vehicle and cause it to deviate from the straight line motion and to what extent. These irregularities had three different maximum amplitudes which enabled analysis of vehicle’s acceleration on the less and the more uneven road. Also, almost the same and almost different profiles were assumed for the left and the right wheels of the vehicle’s model. Some additional phenomena such as the ice on the road have been taken into account. The initial speed was 20 km/h and after 2 s the vehicle started to accelerate. Then, after 8 s the simulation stopped, which gave the whole simulation time equal to 10 s.
