Opis:
The future of automotive industry is to design and develop electrical vehicles to control the emissions released from gaseous fuels and not to release any harmful gases in to atmosphere. In this work, an attempt was made to analyze the behavior of two wheeler E- bike with alternative materials of frame such as Aluminum alloy (Al-A), Titanium alloy (Ti-A), Grey cast iron (G-CI), Carbon fiber epoxy (CF-E), and Structural steel (ST-S) and compared with AISI-1020 material. The frame of Yamaha R15 is initially modeled by using solid work and imported to Ansys. Static analysis was performed by applying a load of 1500 N on the frame and Impact analysis was performed by applying velocity of 27.7 m/s along X direction. The values of equivalent von Mises stress and total deformation for all the materials are observed. After performing static analysis, it was observed that, CF- Epoxy material exhibited higher value of Equivalent von Mises stress (7.659*107 Pa) and lower total deformation of (0.304×10-6 mm) compared to remaining materials. Based on impact analysis , it was observed that, CF-E exhibited better von Mises stress of (3994.9 MPa) closer to AISI 1020 and structural steel materials and total deformation is observed to be lower value (0.1106 mm) compared to remaining materials.

Opis:
Prosthetic legs are mainly used to perform leg amputations more easily and sometimes the appearance is similar to a real leg. Different types of legs have been developed in recent days to be used in specific fields like running, cycling in sports and normal walking. The selection of materials and load bearing capacity of a leg determines its usage for any field of application. The behavior of prosthetic legs can be assessed properly by performing a finite element analysis on it with varying material properties and loads before it undergoes a designing and manufacturing stage. In the current study, Al alloy, Ti alloy, unidirectional Carbon fiber epoxy (UDCFE) and combined composite material which include (CF, UDCFE and Ti alloy) are used as materials for the prosthetic leg. A prosthetic leg model of C Type with its main parts being the sleeve, the rod and the base foot was designed initially by using the Solid Works 2010 software and the assembled file was imported to Ansys Workbench 2020 to perform a static and fatigue analysis. The static analysis was performed under four different load conditions, i.e. 60 kg, 70 kg, 80 kg and 90 kg, considering the different human weights of the body. A fatigue analysis was done by using the Soderberg method and applying a sinusoidal varying load for low cycle fatigue conditions. Theoretical calculations were also performed at various inclinations of foot 10°, 20°, and 30° with the ground and stresses were evaluated using finite element equations. The results obtained theoretically were compared with the analytical results. The best material which provided the lesser value of deformation and sustaining more loads with a lower value of the damage factor was selected for the design. Further experimental studies were suggested based on the results obtained from this work.
