Titanium alloys have an excellent strength-to-weight ratio. Tit alloys are almost as strong as steel but are much lighter. This translates into reduced mass in means of transportation (e.g., aircraft, F1 cars, electric vehicles, and motorcycles), which translates into better fuel efficiency, speed. Titanium can withstand very high temperatures without losing its mechanical properties. As a result, it has found applications in exhaust systems, hydraulic lines, fuel systems, and structural elements exposed to extreme conditions. In the construction of means of transport, two types of titanium with different structures are mainly used (alpha titanium and alpha + beta titanium). There will certainly soon be a need to weld these two dissimilar materials together. This is a research gap. An absolute novelty is the attempt to weld dissimilar titanium alloys without using a protective vacuum chamber. The purpose of this article is to establish the correct parameters for this process.

TRIGGO is one of the first vehicles to effectively combine the manoeuvrability and parking advantages of twowheelers with the safety and comfort features comparable to those of small passenger cars. It is intended for use in a short-term rental network and should be characterised by low energy consumption. To this end, it is reasonable to optimise the vehicle's design towards minimising weight. The use of composites in the TRIGGO body structure enabled a reduction in the ready-to-drive vehicle weight and optimal utilisation of the available space. This choice makes it possible to keep the body weight low while ensuring appropriate mechanical properties. The subject of this paper is numerical analyses of the strength and stiffness of the TRIGGO light vehicle body made of glass-epoxy composites. The scope of the work includes the construction of a computational model of the TRIGGO vehicle body made by the RTM method with a double skin and foam core, in addition to calculations of the stiffness and strength of the structure during body load tests. For this purpose, an FEM computational model was built based on the 3D body model. The body of the RTM version of the TRIGGO vehicle consists of 27 separate components, which are connected to each other by rigid bonded contacts. The composite structures with foam cores were modelled as single-layer shell elements including all the layers of the composite, and a foam spacer. Three design cases were developed: P1.1 - vertical-transverse body loading, P1.2 - vertical-longitudinal body loading, P1.3 - vertical-longitudinal body loading with a horizontal force component. The calculation cases were determined based on "Regulation (EU) No 168/2013 of the European Parliament and of the Council with regard to requirements for the functional safety of vehicles for the approval of two- or three-wheel vehicles and quadricycles", in particular Annex XI of this document. The calculations prove that the glass-epoxy body of the TRIGGO light vehicle meets the requirements for strength and stiffness.

Composite materials due to their outstanding mechanical properties and light weight are becoming increasingly im portant in the automotive industry, helping to develop lighter, more durable and environmentally friendly vehicles. It is espe cially important in the context of electric cars such as TRIGGO. It is an innovative electric vehicle (EV) designed with a focus on urban mobility. One of the unique features of this car is its compact design, aimed at providing a flexible solution for city driving. In this paper a method for manufacturing composite components of the TRIGGO electric car body by pressing tech nology, based on the innovative A.S.SET resin is described. It was confirmed experimentally that selected components of the TRIGGO vehicle body are feasible to be fabricated by pressing technologies using SemiNEMpreg pre-impregnated material based on A.S.SET epoxy resin. The studied technologies cover thermoset sheet forming using a membrane press or a hydrau lic press, also using a vacuum-assisted oven. These technologies were adapted to the requirements of manufacturing composite parts, with a special focus on the cost-effectiveness of the process. Owing to the use of the fast-crosslinking snap-cure epoxy resin with the trade name NEMresin (known as A.S.SET), it was possible to shorten the crosslinking process to 15 minutes. The studies made it possible to select the type of mold depending on the geometry of the component and the applied technolo gy. The studies led to the determination and matching of the type of component to the type of mold and predestined manufac turing technology, taking into account the most important factors affecting the start of mass production, such as the number of pieces, the surface quality of the component, i.e. roughness coefficient and surface finishing, mold cost, process time, pro cess cost, required repeatability, quality of the target component structure, as well as the cost of finishing. The developed technologies are innovative and allow the low-cost batch manufacture of composite parts for the automotive industry.

The article aims to explore and tackle safety issues, including emergency evacuation schemes in the DURA Automotive CZ LP, using the Pathfinder simulation program by Thunderhead Company. We ran twelve simulations, where six tested the existing conditions and six evaluated the implemented remedial measures. The simulation input data involved two parameters, including full occupancy, morning and afternoon (night) shifts. The first simulation profile observes ČSN 73 0804 [4], while the second implementation complied with Kady, Rani A and Davis, Peacock et al. [9] profiles. Each survey determines different average speeds on a flat surface and staircase to identify and remove impediments in the evacuation scheme, including a critical number of people on the first floor and using the only emergency exit within the fire escape. The suggested remedial measures must observe the necessary evacuation time before and after introducing the preventive action, the essential parameter for evaluating the effectiveness of evacuation procedures.

The aim of the research was to select a material from which a washer can be made, so that it can be connected to an E355 steel tube by Rotary Friction Welding (RFW). It was decided to choose the steel grade X6CrMo17-1. The numerical model of the RFW process was built using the finite element method (FEM) using the ADINA System software. The numerical model takes into account the friction coefficient with variable values depending on the temperature. Numerical simulations of the process made it possible to determine the temperature fields in the weld cross-section. For the assumed process parameters: rotational speed of 14,000 rpm, friction time of 1.5 s and friction force of 600 N, the peak temperature occurred in the middle of the friction surface at the end of the friction phase and amounted to 1050 C. The results of the temperature analysis are one of the most important parameters for the implementation of subsequent calculations, such as the calculation of structural changes, hardness, residual stresses and deformations.
