<p>In Taiwan, arched groundsill is frequently used as soil-and-water conservation structures for stabilizing creek bed, guiding flow direction, decreasing the slope of creek bed and reducing the scour effect. Even though much more arched grounsill was built in wild creek recently, its mechanical mechanism is still unclear.</p><p>In order to explore the characteristics of arched groundsill, this study intends to find out the scale of stress, moment and displacement distribution on the various curvature arched groundsills by means of the structural analysis software, ABAQUS. Simultaneously, the three-dimensional computational fluid dynamics software, ANSYS-FLUENT, is applied to show the flow condition of different setups. Preliminary result shows that the maximum stress and displacement of arched groundsill increase with curvature. The maximum moment decreases slightly firstly and increases sharply later with curvature.</p>

Abstract: In this study, we will be performing structural analysis on the motorcycle winglet. The type of winglet used in this analysis is a square winglet from Aprilia RSV4 RF. The flap inside the winglet will be a NACA 6412 airfoil which will be placed upside down to generate downforce. It is very complicated to get results from the winglet. the analysis will be carried out on an active winglet. we will be considering 5 scenarios in Computational fluid dynamics, and 4 in the static, and 6 in vibration analysis. The CFD analysis will be done to obtain the force which later will be applied in the static analysis and vibration analysis to check the vibration frequency at different modes. The material used for the wing and for the body of the motorcycle will be carbon fiber reinforced polymer. As we will be changing the angle of the flap which is present in the winglet it necessary to check whether the CFD results are practical example the forces, coefficient of drag, etc. to prove that the design works. The FEA will help us prove that the design is safe. The model is designed in the Onshape which is a CAD modeling tool and the analysis will be done on the Simscale.

In today’s aviation world, the design of aircraft wing becomes a challenging one for aeronautical engineers, in order to meet the aero elastic phenomenon such as flutter, wing divergence in both aerodynamics and structural aspects. There are so many FEM packages available for both flow and structural analysis such as ANSYS, NASTRAN, ALGOR, NISA, ADINA, COSMOS, etc. The paper presents the application of computational aero-elasticity (CA) methods to analyze the wing in both aerodynamic and structural aspects, using ANSYS-FLOTRAN; 2-D typical aerofoil sections were analyzed and validated with experimental results. Also the vibration behavior of wing section is analyzed under MODAL, HARMONIC, TRANSIENT and SPECTRUM analysis under the aerodynamic lift force and moments. The support reaction forces and moments at the fuselage-wing intersection are developed in this research.
