Numerical analysis of deflection for the existing solution of the friction lift carrying ropes suspension was presented in this article. A similar analysis for the optimized bracket of the carrying ropes suspension was demonstrated from the geometrical point of view. Finite Element Method was used for calculations. It allows mapping the actual operating conditions by using commercial SolidWorks software. Geometrical modifications of the bracket were proposed to save time of manufacturing the detail parts. On that basis, the calculations of percentage indicator of the construction damage and its durability were performed in both cases .

“…Pande and Barve [40] presented the results of finite element-based numerical studies on the forming of CP Grade 4 titanium sheets. Adamus et al [41] numerically simulated the SPIF of CP titanium (Grade 1, Grade 2 and Grade 3) thin-walled panels using the finite element method. However, the above-mentioned works did not analyze the influence of friction stir rotation-assisted heating of the workpiece on the formability of titanium sheets.…”

Single point incremental forming (SPIF) is becoming more and more widely used in the metal industry due to its high production flexibility and the possibility of obtaining larger material deformations than during conventional sheet metal forming processes. This paper presents the results of the numerical modeling of friction stir rotation-assisted SPIF of commercially pure 0.4 mm-thick titanium sheets. The aim of this research was to build a reliable finite element-based thermo-mechanical model of the warm forming process of titanium sheets. Finite element-based simulations were conducted in Abaqus/Explicit software (version 2019). The formability of sheet metal when forming conical cones with a slope angle of 45° was analyzed. The numerical model assumes complex thermal interactions between the forming tool, the sheet metal and the surroundings. The heat generation capability was used to heat generation caused by frictional sliding. Mesh sensitivity analysis showed that a 1 mm mesh provides the best agreement with the experimental results of total forming force (prediction error 3%). It was observed that the higher the size of finite elements (2 mm and 4 mm), the greater the fluctuation of the total forming force. The maximum temperature recorded in the contact zone using the FLIR T400 infrared camera was 157 °C, while the FE-based model predicted this value with an error of 1.3%. The thinning detected by measuring the drawpiece with the ARGUS non-contact strain measuring system and predicted by the FEM model showed a uniform thickness in the drawpiece wall zone. The FE-based model overestimated the minimum and maximum wall thicknesses by 3.7 and 5.9%, respectively.

The numerical results of superplastic punchless deep drawing of the Ti-6Al-4V titanium alloy were presented in this paper. The material behavior subjected to the forming process was characterized by deformation-microstructure constitutive equations including the grain growth. Superplastic stress-strain characteristics used in the numerical simulations were computed with the application of authorial program. The explicit integration scheme is used in solving differential equations. The numerical simulations of the super-elastic deep drawing were made with finite element method analysis. The von Mises stress distribution in the blow-forming process was obtained. The possible faults of extrusions caused by the improper load history as well as unsuitable pressure were also presented in this paper. The numerical simulations included in this research allow for the proper choice of material and drawing parameters which can help to optimize the superplastic forming process.
