“…This is important because a mount failure during testing can lead to engine failure and a consequent increase in engine development costs and time. Similar studies to those presented above have been performed not only for engine mounts but also for other load-bearing structures [13]. Another interesting approach is the possibility of analyzing the entire prototype structure for strength analysis, as presented for composite material and a floating ship mount in the publication [14].…”

The article presents the results of numerical simulations using the FEM (Finite Element Method) of the engine mount strength for mounting an aircraft diesel engine with opposite pistons called PZL-100. Four versions of the mount prepared by aircraft engine producer WSK "PZL-Kalisz" company were analyzed. Tests were performed in Catia v5 software in the Generative Structure Analysis module. The boundary conditions were engine gravity force, propeller thrust force, and propeller torque. S235JR steel was defined as the material. A design grid with tetrahedral elements with a single element size of 2 mm was used. As part of the simulation study, four structural solutions for the test engine mounts were calculated in terms of strength. The results of stress maps and the magnitude of deformation of the mount elements were compared. Based on the obtained results, one of the mount versions was recommended for actual fabrication.

Overhead cranes are widely used in industrial systems. In this study, the research object is the main box girder of the overhead crane. The research objective is to find the parameters to obtain a lighter structure, which reduces the market price of the crane. The article studies the method of calculating crane girders and sets up the optimization algorithm. The study will use the Taguchi method, and ANOVA analysis to evaluate the influence of box girder parameters. The girder weight, stress, local stability, static displacement, and vibration frequency are response values. Constraint conditions are evaluated by examining each factor with response value according to the orthogonal matrix L16. Analysis of the Signal to Noise ratio and ANOVA by Minitab software will select the optimal parameters that satisfy the constraints, the goal is to reduce the volume compared to the original design. The test results of the crane with a lifting capacity of 250 tons, an aperture of 31 m, the girder weight reduced by 24.33 %, while the stress increased by only 6.16 %. The new design ensures suitable local stability conditions by making better use of the material's capabilities. With the new parameters, the technical criteria are guaranteed.

“…A series of numerical simulations using FEM was carried out to confirm this thesis. Computer simulations are currently the basis of engineering activities, they are used to design structures and select materials [9], optimize existing structures [10] or diagnose the causes of damage. In the case under consideration, it was assumed that the damage to the tank was caused by stress corrosion cracking.…”

The paper shows research on a closed fermentation chamber (CFC) that is an element of the Biogas Combined Heat and Power Plant located in the Gdańsk East Sewage Treatment Plant. This tank is mounted as an aboveground cylinder-shaped structure covered with a cone-shaped roof. Corrosion and leaks appeared in the tanks during many years of operation. In this work, it was decided to investigate their cause and propose a method of counteracting them. The article presents the research on the influence of individual operational and environmental loads on the stress distributions in the tank structure. Numerical simulations using the Finite Element Method were carried out for shell and solid models. Moreover, the stress distributions in cylindrical steel tanks were compared depending on the shape of the chamber top. The research results allowed us to identify the design errors of the closed fermentation chambers. It finds out that the connection of the cylindrical part of the tank with the conical roof requires reinforcement. A tank repair technology using Belzona composites was proposed to modify the joint geometry. A simulation was performed, taking into account the proposed repair technology. Its results showed a reduction of stresses compared to the state before repair by 19%.
