“…This method was used in [ 16 ], the purpose of which was to develop an inexpensive, fast and effective method of welding stub pipes to the shell of a cylindrical tank without the formation of large shell distortions. A description of how to prepare the FEA model for this application can be found in [ 27 ].…”

Stress calculations are necessary to determine the feasibility and profitability of a heat storage tank’s construction. The article presented normative methods of stress calculations for a heat storage tank. Results were verified by finite element analysis. These stress calculations enabled us to determine wall and weld thickness. The calculations were made on the example of a tank with a nominal pressure of 10 bar. The work undertook an extensive analysis of the stresses occurring in a pressure tank, described the finite element method and showed examples of ways in which it could be used. During stress analysis, three types of materials were compared: carbon steel St0 (S185), stainless steel (304) and boiler steel (P 265 GH). A brief overview of types of thermal energy storages was also provided.

“…Welds are modelled by direct connection between plates to be welded by means of forcedeformation constraints, also known as Multi Point Constraints. The technique of modelling welds by rigid connections was suggested by Fayard and Bignonnet (1996) [6], and can also be found in various scientific papers such as [7], [8], [9] or [10].…”

Summary The current standards are based on the well‐known component method for the design of steel structure connections. This method proposes to analyse the joints as a set of more basic components. Its main drawback is the difficulty in extrapolating the method to perform the analysis of complex joints. As an alternative, it is possible to test the joints in the laboratory or to carry out finite element modelling. The purpose of this study is to compare the strength obtained on the basis of the Eurocode 3 criteria with the strength obtained from finite element models of two‐dimensional elements in order to validate a model which, a priori, is less accurate than the three‐dimensional element model.

“…In the 1960s, Crandal [1] firstly proposed the concept of vibration fatigue, and he clarified that the source of excitation for fatigue damage of structures is related to the vibration of the structure itself, but compared with the traditional definition of fatigue, it does not clearly point out the essential connection between the dynamic characteristics of the structure itself and the environmental vibration in vibration fatigue [2][3] . Yao Qihang and Yao Jun [4] put forward a clearer definition of vibration fatigue of mechanical structures by summarizing the fatigue damage phenomena of a large number of structures in the process of actual use and in the process of testing.…”

With the rapid development of the rail transit industry, the running speed of vehicles has been continuously improved, and the operating environment of different types of vehicles is complex and changeable, which makes the load on the vehicle structure randomly variable, and the possibility of fatigue failure is also increasing, which seriously affects the driving safety. Therefore, it is of great practical significance to study the fatigue life of rail vehicle structural parts by vibration fatigue life evaluation method. In this paper, the random vibration fatigue life prediction method is studied in depth based on the application background of rail vehicles and the vehicle body with large bearing structure. The rigidflexible coupling dynamic model and longitudinal dynamic model of high-speed train with flexible body are established. And a finite element model of the high-speed train body was also established. Given the limitations of the measured load spectrum of the vehicle body, a low-frequency load spectrum inversion method for the measured acceleration of the vehicle body is proposed, providing a new approach for the inversion of the vehicle body load spectrum. Based on the proposed load spectrum inversion method, under the excitation of the Wuhan Guangzhou Railway track spectrum track, the load spectra of the center of gravity of the vehicle body, including pitching, swaying, expansion, nodding, rolling and yawing, were obtained. The fatigue life assessment of the vehicle body was calculated under various line conditions under this load spectrum. The results indicate that the cumulative damage to the door and window angles of the vehicle body is significant, and maintenance should be emphasized.
