Morphing Wing for Trucks: Greater Stability in Cornering

获奖作品摘要

The following scientific research seeks to determine through computational analysis and experimental tests; which is the best angle of attack to achieve greater stability of a truck of an inverted NACA 2412 Morphing Wing when cornering. The hypothesis establishes that when designing an inverted NACA 2412 Morphing Wing, and being adjusted to an angle of attack of 60°, it will reach its optimal condition for the increase of downforce; therefore, improving the stability and efficiency of the truck during cornering. The research consists of three parts. In the first part, a computational design was created and behavioral simulations were conducted which allowed to obtain more accurate data for the wing design. Then, the inverted NACA 2412 Morphing Wing prototype was built. To validate the results obtained by computational analysis, experimental tests were carried out using the prototype. In conclusion, after performing two sections of five tests using different positions of the angle; it was determined that the best angle of attack is between 55 and 60 producing a downforce near the 33% of the truck mass; using less air resistance. However, between 55 to 60 there is a 0.3% of downforce difference because it depends on atmospheric conditions.  It was determined that there is a stability increase of 3% to 4%, having a 1.3% difference in real scale truck when compared to the proportion of the speed prototype. These results will be of great benefit to implement in any design of morphing wings for greater stability in trucks.

学科简介：工程力学 Engineering Mechanics

Studies that focus on the science and engineering that involve movement or structure.  The movement can be by the apparatus or the movement can affect the apparatus.

Subcategories:

Aerospace and Aeronautical Engineering (AER): Studies involving the design of aircraft and space vehicles and the direction of the technical phases of their manufacture and operation.

Civil Engineering (CIV): Studies that involve the planning, designing, construction, and maintenance of structures and public works, such as bridges or dams, roads, water supply, sewer, flood control and, traffic.

Computational Mechanics (COM): A study that applies the discipline and techniques of computer science and mathematics to solve large and complex problems in Engineering Mechanics.

Control Theory (CON): The study of dynamical systems, including controllers, systems, and sensors that are influenced by inputs.

Ground Vehicle Systems (VEH): The design of ground vehicles and the direction of the technical phases of their manufacture and operation.

Industrial Engineering-Processing (IND): Studies of efficient production of industrial goods as affected by elements such as plant and procedural design, the management of materials and energy, and the integration of workers within the overall system. The industrial engineer designs methods, not machinery.

Mechanical Engineering (MEC): Studies that involve the generation and application of heat and mechanical power and the design, production, and use of machines and tools.

Naval Systems (NAV): Studies of the design of ships and the direction of the technical phases of their manufacture and operation.

Other (OTH): Studies that cannot be assigned to one of the above subcategories. If the project involves multiple subcategories, the principal subcategory should be chosen instead of Other.
