MR Fluid bicycle suspension system

Abstract

Bicycles are an important element of society, and they are becoming more popular in industrialised countries as a result of climate change concerns. Suspension systems come in a variety of configurations on cross-country, downhill, and mountain bikes. Bicycle suspension technology has progressed from seats with suspension springs in the early 1900s to the numerous complicated designs of today's bicycles. Suspension design receives a lot of research and development money in the competitive cycling industry. Designers of bicycles have recently begun to use electrically controlled components such as drive systems and gears. Hydraulic damping is a typical design in bicycle suspension systems, and it works by squeezing a viscous fluid through a valve or a small gap in a plunger connecting the bicycle frame to the wheel, creating a force in the opposite direction of motion, decreasing the suspension's rate of motion.Electromagnetic magnetorheological (MR) suspension systems are now being used in automobiles, resulting in improved ride quality and control. Adding ferrous particles to the oil and applying a magnetic field to align the particles, decreasing the flow velocity of the oil and increasing oil viscosity in accordance to the strength of the electric field, is known as magnetorheological suspension. This final-year Mechanical Engineering project attempts to design an electromagnetic magnetorheological bicycle front suspension by combining two working technologies. To contrast it to conventional hydraulic bicycle suspension, the suspension system was created, manufactured, and tested.
