“…Therefore, innovative design cannot be limited in terms of architecture. It must also contend with issues including the adaptability of the vehicle architecture, the effective coordination of numerous actuators, and safe operation in the event of a malfunction, all of which need to be considered while designing the chassis[7].In the context of the requirement of new energy vehicle lifetime, increasing premise and battery energy density temporarily no breakthrough progress, the other systems can streamline, reduce occupation volume, and reduce the weight of the parts is the trend.…”

More focus has been placed on creating new energy cars that are safer and more energy-efficient due to the development of new energy vehicle technologies and their strategic importance in addressing current energy and environmental issues. The chassis system's primary components, whether for a conventional fuel vehicle or a new energy vehicle, are the braking, suspension, and steering subsystems. The functioning, comfort, and safety of modern energy vehicles are strongly correlated to their structural design. At the moment, the design of new energy vehicle chassis is mostly based on refining and adapting the chassis of conventional fuel vehicles. However, new energy vehicles have distinct driving systems compared to conventional vehicles. Thus it is important to account for these variations in the layout and make it compatible with the whole system. The chassis structural design of new energy cars is more adaptable and affects vehicle performance compared to fuel-powered vehicles. The integrated battery and high amount of unsprung mass affect the center of gravity and stability of the new energy vehicle. The coordination and collaboration between the power battery module and the chassis construction must therefore be carefully considered, as well as their effects on the entire vehicle performance, including its safety and economic effectiveness. In conclusion, thoroughly examining the chassis structure design plan for new energy vehicles is crucial for advancing these vehicles.

“…Various methods, both passive and active, have been proposed to enhance aerodynamic performance. These methods include the application of a sinusoidal surface [3], the use of air jets [4], the vortex generators [5], the implementation of split blades [6], and the combination of airfoils with vortex generators [7] on their surface and microcylinders [8].…”

“…The impact of microcylinders is most often tested at large rake angles of 16-23 • , as these angles generate boundary layers that are influenced by strong pressure gradients [9]. The addition of microcylinders delays flow detachment [8]. An important factor influencing the effectiveness of microcylinder additions is their location relative to the airfoil.…”

This study aims to evaluate the effect of circular-shaped microcylinders on the flow field around an airfoil, using time-resolved particle image velocimetry. The results show that microcylinders can significantly modify the flow pattern around the NACA 0012 airfoil. The optimal configuration of microcylinder-airfoil depends on the angle of attack and the position of the microcylinder. The obtained results have practical implications for the development of more efficient and sustainable aircraft designs and wind turbine blades. The paper presents a physical analysis of flow fields using streamlines and vorticity structures to illustrate mechanisms of flow control for improving the aerodynamic properties of the airfoil. Overall, this work provides new insights into the fundamental physics of flow control using microcylinders, including general physics and optics, with potential application in various contexts, such as aerodynamics, flow control, airfoil design, optical diagnostics, and particle image velocimetry techniques. topics: velocity measurements, optical method, experiments, time-resolved particle image velocimetry
