Design analysis and fabrication of revolving car seat using composite materials

Abstract

Now day s the cars are highly sophisticated in driving and seating arrangement. but in the front seat is close to the driving seat (especially in a 3+1 seating arrangement cars) moving only front and back with some lever mechanism. this type of design is not suitable for physically challenged persons and ill person. newlinethis project involves that design and fabrication of a car front seat with linear movement (front and back movement) as well as revolving (around 1800) movement with folding feature also. the linear movement can be achieved by the rail and track mechanism and the revolving movement can be achieved by the swivel plate mechanism, both are operated by hand lever and body adjustment. the entire mechanism should withstand the human load braiding a compact and comfortable and cushioning effect for the human body. materials can selected from various composites based on that and composite materials can be fabricated and can be applied for specific applications. weight reduction is a major task for automobile components. hence lightweight materials have to be utilized in the manufacturer of the automobile components. magnesium alloy is the ultimate choice for light weight and better performance. magnesium alloy also exhibits high fatigue strength compared to other lightweight materials. the swivelling mechanism enables a 360 0, rotation of the seat. this mechanism can be achieved using a swivel plate. the research problem adopted for this study is exploratory based on a survey study and iso standards for automobile seat design using comfort and discomfort methods. the research design also includes vibration analysis using numericals and analytical methods followed by experimental method. so, based on the survey of a study of old persons, handicapped, physically ill newline newline
