Abstract This paper presents a strength analysis of a calcaneal nail (material Ti6Al4V and stainless steel) which is used to treat complex heel fractures. The application focuses on a unique calcaneal nail, the C-NAIL, produced by Medin a.s. (Nové Město na Moravě, Czech Republic). The paper first presents an analysis of fracture types, treatment methods and loading of the calcaneus. It then presents an analysis of limit conditions and loading. Calculations (displacement and stress) are performed for 6 and 7 fixing screws using FEM (Ansys Workbench 14 software). The calculation involves a new, original application of an elastic foundation, which effectively replaces the complex interaction of the calcaneal nail and the heel bone.

For high-speed permanent magnet (PM) electrical machine, the PM material has very small tensile stress, and it can’t withstand the huge centrifugal force. So, a high-strength sleeve with interference fit is necessary to protect the PM. This paper mainly analyzes the strength of rotor sleeve and PM. It deduces the theoretical calculation method of the strength according to Lame equation, and it also analyzes the stress of sleeve and PM by ANSYS Workbench. The result show that the theoretical calculation value is closely to the ANSYS result, and it can meet the requirements of protecting the permanent magnet in high rotation speed.

The theme of this article is the design and strength analysis for two types of rotary seals which use shape memory materials to the radial terminal. In this paper, basic types of technical seals were brought up and shape memory materials were described. Based on these pieces of information and product catalogue of Trelleborg, there were designed two types of seals with coils of wire and shape memory. After the project of building the seals was prepared, strength tests were carried out in ANSYS Workbench program. In the case of the seal type TRG two types of analysis were carried out: the first simulating the assembly of the seal, and the second, which is the extension of the first, including additionally the coil terminal of wire. For the seal type TRA, two types of analysis were conducted as well: the first including assembly and coil terminal and the second comprising additionally loading the seal with working pressure. After selecting the materials, declaring the environment and the loads with accordance to the findings of the analyses and performing computations the results were provided. As the output there were chosen: the total reduced deformation, reduced stress and reduced load.

Background: As a key component of the rail transit vehicle, the railway bogie greatly affects the dynamic performance, reliability, and safety of the high-speed rail vehicle. In this paper, the structural strength of a typical trailer bogie frame is evaluated and its strength and dynamic requirements are verified. In addition, various patents on bogie structural strength have also been discussed in this paper. Objective: The study aimed to evaluate and verify the rationality of the bogie frame structure design with static strength and dynamic characteristics. Methods: A three-dimensional model of the trailer bogie frame was built by CATIA V5, and then, a finite element model of the frame was analyzed by ANSYS Workbench. Bogie frame loads, static strengths and dynamic characteristics of the frame under different conditions (straight, curve, braking and abnormal) were calculated based on its strength and design standards. Results: According to the requirement stress and dynamics standard, the maximum stress of the bogie frame was observed to be in the allowable stress value of the frame material, and the dynamic performance of the bogie model meets the design standards. Conclusion: The structural strength of the proposed bogie frame is reasonable, and the static strength and dynamic characteristics of the proposed bogie model are in accordance with the design requirements of the railway vehicle.

The stainless steel are employed in a wide range of structural application such as in bridges, storage tanks, reinforcing bars for concrete structure, etc. Among the various grade of stainless steel, austenitic grades are generally popular in construction industry which has nickel content 8-11%. The demand for a new form of a duplex stainless steel leads to the development of Lean Duplex Stainless Steel (LDSS), which has a low nickel content of about 1.5%. The paper is investigates the buckling performance of different shaped lean duplex stainless steel hollow stub column with stiffener. Also performance of LDSS stub column compared with concrete stub column. A non-linear static analysis of LDSS stub column was studied using ANSYS workbench.
