Optimization and Analysis of Front Telescopic Suspension for Electric Bike to Have Comfortable Ride: India Perspective

As per current government directives, every automobile OEM has to come up with EV model by 2020. But current Indian road conditions demand variation in torque requirement which leads to uncomfortable ride and so affecting the battery life of electric bike. So there is a need to optimize existing traditional suspension system to experience better and comfortable ride with electric bike which may lead to extend battery life. With this objective, present research and development work initiated to design, develop, and analyze traditional suspension system specifically for an electric bike on bumpy roads using simulation behavior of the spring and damper. The study involves development of solid CAD model of two inverted telescopic spring and damper systems, viz. primary and secondary and virtual simulation of the CAD model in ADAMS software. Spring and damper systems are joined together with different set of attachments and classified them as traditional and optimized one to achieve the desired objectives. To compare the traditional and optimized suspension system, transmissibility analysis at bump size of 10 cm and 3 cm is carried out and corresponding stress developed in shackle plate and fork body is also analyzed to make sure that stresses are within permissible limit of material.
