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.

Carbon fiber reinforced polymer (CFRP) strips are widely used all over the globe as a repair and strengthening material for concrete elements. This paper looks at comparison of numerous methods to rehabilitate concrete beams with the use of CFRP sheet strips. This research work consists of 4 under-reinforced, properly cured RCC beams under two point loading test. One beam was loaded till failure, which was considered the control beam for comparison. Other 3 beams were load till the appearance of initial crack, which normally occurred at third-quarters of failure load and then repaired with different ratios and design of CFRP sheet strips. Afterwards, the repaired beams were loaded again till failure and the results were compared with control beam. Deflections and ultimate load were noted for all concrete beams. It was found out the use of CFRP sheet strips did increase the maximum load bearing capacity of cracked beams, although their behavior was more brittle as compared with control beam.

Cylindrical Holes

Ultrafast laser drilling has been proven to effectively reduce the heat-affected zone (HAZ) of carbon fiber-reinforced polymer (CFRP) composites. However, previous research mainly focused on the effects of picosecond laser parameters on CFRP drilling. Compared with a picosecond laser, a femtosecond laser can achieve higher quality CFRP drilling due to its smaller pulse width, but there are few studies on the effects of femtosecond laser parameters on CFRP drilling. Moreover, the cross-sectional taper of CFRP produced by laser drilling is very large. This paper introduces the use of the femtosecond laser to drill cylindrical holes in CFRP. The effect of laser power, rotational speed of the laser, and number of spiral passes on HAZ and ablation depth in circular laser drilling and spiral laser drilling mode was studied, respectively. It also analyzed the forming process of the drilling depth in the spiral drilling mode and studied the influence of laser energy and drilling feed depth on the holes’ diameters and the taper. The experimental results show that the cylindrical hole of CFRP with a depth-to-diameter ratio of about 3:1 (taper < 0.32∘, HAZ < 10 m) was obtained by using femtosecond laser and a spiral drilling apparatus.
