“…The first step of optimization process, which was common for both structures, was to create the input model for the further numerical optimization. The process was based on several iterations and previous experience in order to obtain an optimal layout of the vehicle's subsystems and their mounting points in a scope of performance and loads reduction [13]. Even though this stage of the development was common for both structures, the general results were further adjusted for the particular design, as different types of system enabled or required some particular features.…”

“…In the general approach, the optimization process of any more complex system should be divided into few smaller steps, in order to increase its effectives and time efficiency. In the case of the supporting system for the electric vehicle, the procedure can be divided into three main areas of optimization [13]. This division was shown in Fig.…”

“…The second stage of the numerical optimization was the inner structure of the laminate optimization, which was based on both shape and size optimization techniques. This stage consisted of three main consecutive stages, that is the optimization of a shape of plies of particular material and orientation, the optimization of thickness of resulting patches of material, with taking into consideration their lower and upper manufacturable limits, and finally of the sequence of the plies in a stack [13,14].…”

When designing an ultra energy-efficient vehicles it is extremely important to ensure the lightweight vehicle's structure. The compromise between the fulfilment of functional and strength requirements can be achieved by using a spatial shell or frame design. The paper presents a comparison of these two concepts of the supporting structure of such a vehicle, at the same time analysing the pros and cons of each of them. The method of optimizing the structure of both load carrying structures was proposed, as well as technical, technological and functional details related to these concepts were analysed. For the purposes of optimization, the method of topological optimization was used, modifying the assumptions for each of these concepts and iteratively adapting to the specific technology of making the vehicle's body. The numerical simulations were carried out for a previously selected outside vehicle's surface, optimized in order to minimize the aerodynamical resistance forces.

Car industry has dynamically developed the electric car segment and is always on the lookout for new solutions that could help a company to become a leader brand on the market. Besides fully autonomous car technologies also new mechanical solutions could give advantage over other companies. Thus many ideas have been made to replace conventional vehicle suspension by the use of a flexible wheel rim. Based on over a year of experience, researches and studies in a field of existing lightweight vehicle suspension systems it was decided to design new solution, which structure eliminates main disadvantages of existing solutions such as energy losses and poor stability. The new suspension solution was designed based on our own knowledge and TRIZ method as a tool of verification. The CAD model of subassembly was subjected to a virtual examination for three different situations: standard ride, hard braking and sudden acceleration. Then a mathematical model of vibration damping properties has been created using MATLAB Simulink software. Additionally, the suspension quality and energy loss analysis have been performed to verify whether the problem was solved. The obtained results have been investigated and compared with commercially used car suspension systems.
