Design and Analysis of Automobile Chasis sing F.E.A

The portable toilets are mounted on the chassis, this chassis is manufactured by a company (ExcellFibrotech, MIDC Nagpur). Many of new product designs are based on existing products and years of experience. Therefore, the chassis is assumed to have unexplored areas of potential improvements. Today the chassis is mainly a welded design, which is both expensive and unsatisfactory from a maintenance viewpoint. Welding is not only expensive but introduces heat to the steel alloy, and thereby changes the material properties, and also requires a high degree of manual labor. A truck chassis has a more standardized manufacturing method and application of some of the manufacturing techniques from it to the chassis could perhaps make the production of it more efficient. The current chassis have robust designs, and there have been no actual calculations or investigation to find out what dimensions are needed to withstand the forces applied to a chassis during use. Instead, the design is based on experience of what works, and what does not. A more thorough investigation of the design parameters can create better understanding of which parts of the chassis that are most exposed to high stresses, and which parts that can have reduced dimensions.
