“…Furthermore, a similar study about the weight optimization of suspension knuckle for a solar race car has already been performed [29], and, for this specific case, it was found out that a 452 g weight reduction in the car represents an energy saving as high as 18.6 Wh.…”

“…For the autonomy, the car should capture as much as possible energy from the sun and spend the lowest possible energy when traveling. The design and manufacture processes take into account: reliability, safety, solar panel efficiency, aerodynamics, weight reduction, among other important considerations (see [4][5][6][7][8]). …”

Solar cars are known for their energy efficiency, and different races are designed to measure their performance under certain conditions. For these races, in addition to an efficient vehicle, a competition strategy is required to define the optimal speed, with the objective of finishing the race in the shortest possible time using the energy available. Two heuristic optimization methods are implemented to solve this problem, a convergence and performance comparison of both methods is presented. A computational model of the race is developed, including energy input, consumption and storage systems. Based on this model, the different optimization methods are tested on the optimization of the World Solar Challenge 2015 race strategy under two different environmental conditions. A suitable method for solar car racing strategy is developed with the vehicle specifications taken as an independent input to permit the simulation of different solar or electric vehicles.

“…In the case of a motor wheel for a solar vehicle, some specific issues must be considered. The development of a solar vehicle is a challenge that has been studied for years because to get out the most of the power generated by solar cells, a strong effort must be paid in reducing the vehicle weight and in minimizing aerodynamical, electrical, and mechanical losses [31][32][33]. In particular, to optimize power consumption, the design of highefficiency powertrain is a crucial aspect.…”

Lightweighting is a need in many industrial fields and, in particular, in transports, to reduce energy consumptions and to promote more environmentally friendly solutions. In this context, the use of composite materials has become ever more strategic, and a design approach that effectively combines shapes and materials is by now mandatory. In this work, the Systematic Design Approach has been extended to include potentialities and constraints related to materials and manufacturing at the early steps of the design flow. The proposed approach, named systematic material-oriented design approach, enables designers to identify and to select, in a systematic way, design solutions where shapes are tailored to materials and where benefits and criticalities related to the manufacturing processes are considered. In the paper, each design phase of the approach is described and applied to design the carbon fiber-reinforced polymer (CFRP) motor wheel of the Emilia 4 solar vehicle. Optimization steps of geometry and materials complete the approach. The design of the wheel is fully detailed as well as its manufacturing and bending tests under static and fatigue conditions. In particular, strain fields were measured with a 3D digital image correlation (DIC) system during static tests to validate the numerical model.
