    This paper proposes a new algorithm for a real time charging recommendation for an electric vehicle (EV) driver based on an accurate real-time range indicator system to avoid range anxiety. In this algorithm the graphical user interface (GUI) of the real-time range indicator system is also used to show the driver an accurate estimation of the remaining range to destination and the current state of charge (SoC). This algorithm also calculates the minimum charging time required at the charging station to reach the destination. Charging recommendation system, electric vehicle, energy management, real-time range estimation model, state of charge estimation these are tools required for implementing this paper. The proposed system will enhance the use of electric vehicles by reducing range anxiety and reduce the necessary charging time along a route and also helps the driver to travel over a longer distance by a depleted electric battery.

    A crack is a type of fracture that separates a solid body into two or more pieces under the action of stress. There are three types of modes of failure, the forces are perpendicular to the crack, the forces are parallel to the crack, the crack is in front back direction, the forces are pulling left and right. Homogeneous material systems, always involve cracks. From dynamics and fracture mechanics, it is well known that accelerated crack nucleation and micro crack formation in components can occur due to various reasons, such as transient load swings, higher than expected intermittent loads or defective component materials. Structural systems may be composed of homogeneous and heterogeneous materials such as composites, plastics, ceramics, fabrics and metal -alloys. The objective of this thesis is to analysis how a crack propagates and grows in a clutch. The finite element program ANSYS is used to simulate crack growth and to compute the stresses and the stress-intensity factor. A Geometric model of clutch was designed in 3D by using software Pro/Engineer. Later the geometric model of the clutch converted into FEM model and get analysed by using ANSYS software to predict the analysis results. In this present work an attempt has been made to estimate the deflection, stresses under the subjected loads and total strain intensity using FEA. The Von Misses stress near the crack tip was compared against the yield strength of the material. The materials of clutch considered are Aluminium alloys 7475, 6061 and composite materials S2. Mathematical correlations are calculated to determine stress intensity factor, crack extension force, crack opening displacement.

    Microcontroller based design, has acquired the status of most happening field in electronics. This is highly specialized field that has the power of integrating thousands of transistors on single silicon chip. Nowadays, in mall for purchasing variety of items it requires trolley. Every time customer has to pull the trolley from rack to rack for collecting items and at the same time customer has to do calculation of those items and need to compare it with his budget in pocket. After this procedure, customer has to wait in queue for billing. So, to avoid headache like pulling trolley, waiting in billing queue, thinking about budget, we are introducing new concept that is “SMART TROLLEY IN MEGA MALL”. For the blind person the special headphones are provided to help them to know the product details. When the blind person takes the product from the track, they are instructed to take the product near to their headphone in which the RFID scanner is inserted in the both headphones. Which scans the product and tell them what product it is and the total amount.

    The world is running out of conventional energy sources. There is a pressing need of utilizing non-traditional energy sources to endure the ever escalating1energy0needs. Wind2turbines provide an alternative way of generating energy from the6power of wind. At windy8places, wind speeds7can achieve scintillating4values of 10-12 m/s. Such high speeds of wind can be utilized to harness energy by installing a wind turbine usually have 3 blades. The geometry of the5 blades is made as such that it generates8lift from the7wind and thus rotates. The lift force generates a moment around5the hub and thus the combined torque effort of 3 blades rotates the turbine and generates electricity. Rotational8speed of the blades is usually 6 times that of wind speed. In this project, validation of a beam (a geometrical approximation of a blade) in vibration analysis is taken up first. The natural4frequencies are matched with a0published research paper and then an actual blade geometry is taken 9 up to validate its 1st 3 natural frequencies with a published research paper and then a6CFD analysis is taken up to find the lift0and drag forces on the blade and subsequently these forces are used to2calculate the fatigue life of the blade. Suitable materials for different parts6of the blades are taken to see which combination of materials gives better results.

    The two widespread causes of failure of threaded fasteners subjected to dynamic loads are fatigue and vibration induced loosening. This report presents the study on a loosening behavior of bolted joint due to transverse vibration caused due to shear load. A three dimensional finite element model is used to study the effect of preload on the bolt. With the aim of developing a general simulation method for rotational self loosening of the threaded fastener under transverse loading .A three dimensional finite element model of bolt is developed in Ansys for detection and understanding of loosening of threaded fastener. In current work, the threaded fastener undergoes self loosening due to applied dynamic shear load which causes the certain failure to the system or part. So, it is necessary to analyze the loosening behavior of threaded fastener so as to nullify the effect of loosening. Cad software like Pro-E 4.0 is used for 3-D modeling of bolted assembly and finite element analysis software ANSYS-13 is used to build the finite element model of bolted assembly to obtain the result. A modal analysis is performed to find out the natural frequency of the assembly.

    In this paper, the analysis is done on the automotive bumper to check the crashworthiness for the passenger safety. The bumper beam analyzed for the steel and composite material with the basic bumper design in the first phase to compare the deformation and energy absorbed during the impact. A design of the automotive bumper must ensure the safety of passenger mean while, it needs to have low weight. With the role of safety, fuel efficiency and emission gas regulations are being more important in recent years that enforce the manufacturer to reduce the weight of passenger cars. In this research, a front bumper beam made of steel and composite materials to provide more energy absorption in the structural at the front of the bumper and is studied for impact modelling to determine the deformation and energy-absorption behavior.

    The braking system is a process that converts the kinetic energy of the vehicle in the mechanical energy that must be dissipated in the atmosphere in the form of heat. In general, a brake disk in cast iron or ceramic composites is connected to the wheel and/or of the axle. The friction materials in the form of brake pads is forced, so mechanical, hydraulic or pneumatic electromagnetically against both sides of the disk to stop the wheel. The present analysis transitional thermal "and the structural analysis of disk brake" deals with the production of heat in the different materials of disk brake with different vehicle speeds and heat dissipation by these materials and also the deformation and the stresses produced in these materials due to the increase in temperature is analyzed. A comparative study is made between these materials to suggest the best material for the brake disk to the aspect of the problem considered. Modeling of the disk brake has done with the help of CATIA V5 and the complete analysis is made using ANSYS 16.0.
