Design of A Driver’s Seat with Magnetic Dampers[ ]


In today’s world, ergonomics has huge value in automobile industry. Better comfort level is one of the top priorities for consumers in passenger car segment. With increasing the comfort for driving, long distance road traveling has become possible. Now a day, vehicles travel from one state to another and even from one country to another. Driving a vehicle is a physical as well as mental task for a driver and it requires higher amount of concentration on road. During long distance traveling in a car, driver has to deal with neck pain, back pain and discomfort in sitting on driver seat for long time. It is due to continuous vibration from the vehicle and impacts on car due to bumps, uneven roads and potholes. It increases physical and mental stresses and anxiety which increases with increase in distance to travel. It causes depression, lack of interest and discomfort while driving. It may also cause long term or permanent physical injuries. Our aim of this project is to design a seat that will absorb vibrations effectively more than a conventional driving seat. By achieving less vibration to the driver’s seat, it will improve overall ergonomics of that vehicle. The research project introduces arrangement of multiple magnets underneath the driver seat with similar poles between two magnets facing each other to avoid physical contact between them due to magnetic flux.

The non-polluting mechanized transport is having an increasing demand and has also revived the internet for its use of electric energy for transportation purposes along with helping reduce dependence on ICE vehicles which contributes to pollution. A better and cheap alternative to this is an electric driven bike. However, due to current conditions and improvement in this field, electric bikes have been limited for short distances or recreational purposes as in for personal use. This paper describes the complete making of an electric bike that will increase the scope of its use by increasing the range of its run per change. This bike consists of two sources of energy. The already charged battery will take the rider to a limited distance, and electric motor running off a 36-volt lead-acid battery. The power module is controlled by a microprocessor, so that the rider can operate the bicycle at a set speed which is also known as cruise control. This power control module attached to the motor will manage and reverse the current flowing from the motor if the speed of bike exceeds the desired speed. This leeds to the generation of current from a third wheel that charges the battery, and thus provides regeneration when moving down the slope, or when the rider is moving faster than the set speed.

Cutting Fluids and Cutting Fluid Application Techniques in Machining: A Review[ ]


In view of the environmental and health hazards associated with the use of conventional cutting fluids together with developing governmental regulations, the cutting fluid type and cutting fluid application techniques are critically important in machining process. The heat generation and temperature at the cutting zone due to the friction at tool-chip interface and tool-workpiece interface are significant parameters which influence tool wear, tool life, surface integrity, chip formation mechanism and hence machining quality. A good understanding of the type of cutting fluid and methods to apply cutting fluid at the cutting zone significantly reduces the heat generation and temperature in machining process improves the tool life and surface integrity. Cutting fluid related costs and health concerns associated with exposure to cutting fluid mist and a growing desire to achieve environmental sustainability in manufacturing lead to re-examine the role of these fluids and quantify their benefits. In this paper, an overview of cutting fluid and its various alternative application methods such as dry cutting, high pressure cooling (HPC), minimum quantity lubrication (MQL) and cryogenic cooling is well presented. These techniques largely minimized the amount of cutting fluids used in machining while providing similar or even better cutting performances compared to wet cooling methods.

Design of Zip Chain Lifters[ ]


Conventional method of lifting include lifting the weight by the help of cranes, forklift or by any type of lifting mechanism. A major problem in lifting and lowering applications is moving loads at a linear rate while maintaining steady and level positioning on vertical and horizontal plane. The factors considered while lifting any object is the durability of the lifter as well as the time and speed required to lift the object. Zip chain lifter employs a lifting mechanism that uses zip chain to directly transmit upward and downward thrust, thus lifting the object. The zip chain lifter consists of chain and sprockets mechanism for transmission of motion and force from one part to another. When lifting, the Zip Chain Lifter engage two zip chains to form a strong, rigid, column-shaped body that pushes up the platform while when descending, the chains are unlinked and moved in a compact housing. Powers are transmitted through a single strand chain when the driver sprocket rotate and the teeth interlock the chain, pulling the chain around it causing it to rotate.

SPUR GEAR TOOTH STRESS ANALYSIS AND MODIFICATION USING STRESS REDUCING GEOMETRICAL FEATURES[ ]


Gears are used for a wide range of industrial applications. They have varied application starting from textile looms to aviation industries. They are the most common means of transmitting power. They change the rate of rotation of machinery shaft and also the axis of rotation. The continuous meshing of the gears is the most common cause of failure of the gears. In order to avoid this problem we have to design the geometrical features of the gears very properly. In the spur gears the tooth surface of the gears is exactly comes into contact with other gear. One of the important parameter of mating gears design is contact stress. In this project, we analyze the spur gear trains of various machines and find the contact stresses on individual teeth under the working conditions. After identifying the problem in the design, we hope to improve upon it by taking two geometrical parameters of a spur gear tooth and try to optimize the design to suit the industry needs.

Analysis of Vehicle Compatibility With Respect to Bumper Design of M1 Vehicles under Crash[ ]


Vehicle safety is one of the vital factors governing the automobile design. According to the road accidents data, the total number of road accidents in India decreased by 4.1 per cent in 2016 as compared to 2015,but the number of persons killed in accidents has increased by 3.2%. In order to improve the vehicle safety the position of bumper is one of the important parameter. Bumper is a structure attached to the front of vehicle mounted with an intention of absorbing some energy in case of impact. The objective of this project is to optimise the height of bumper for M1 category vehicles which reduces the transfer of impact energy to the passenger cabin. This is achieved mainly by optimising the bumper height to reduce the overlapping of vehicles under impact. The modelling of the bumper beam is done in CREO tool and the impact analysis is carried out by using LS Dyna tool. The result shows significant changes with respect to different positions of bumper for M1 category vehicles. The optimized height of bumper with vehicle compatibility shows increase in overlapping of the bumper beam which leads to reduction of impact energy to passenger compartment. This will help in improving the safety of the passengers.
