This report targets some improvement over existing design of paddle operated rickshaw and methodology for a new chassis design and structural rigidity analysis using software simulation (fusion360). The vehicle we have designed in this project is an improved model of existing conventional one. Improving the traditional design in terms of torque requirement and safety cum connivance of passengers is our goal. To improve and fix some of the design, structural and ergonomically flaws of this paddle operated three-wheeler vehicle, we have designed a whole new tubular chassis with a low-profile design to reduce the overall CG of the vehicle and cross members to enhance the structural rigidity. Then we have introduced rear axle wire powered mono disk brake, to improve stopping power without increasing the cost too much. We also have designed a 3 axle 4 sprocket system to deliver power from paddler to rear driving axle. By doing so we are trying to achieve a lower gear (sprocket) ratio with almost no chain de-railing. We have also included an optional gear system. For that we are using an already existing mechanism, Dog engagement gear (sprocket) system instead of conventional mountain bicycle type gear system to reduce cost and maintenance. Mathematical modeling of parts, assembly of the whole vehicle body and the analysis has been done in Autodesk Fusion360 software with academic license. Analysis was done through Finite Element Method using Fusion360.
