The study limits the bicycle riding along a straight path. Therefore, a mathematical model for in-plane dynamic analysis of the bicycle equipped with suspension systems is first constructed. The dynamic equations, which governing the linear and rotational motions of the front and rear tires, the rotations of the swing arm, rear suspension and frame, linear motion of the front suspension, are then developed based on Lagrange method. The braking performance and the vibrations of suspensions of a bicycle riding along continuously bumping road are also analyzed. The braking force mainly results from friction between tires and road. Larger braking force would make wheels lock-up to generate danger. An ideal braking performance curve is drawn based on the distribution of braking forces between front wheel and rear wheel. Riding comfort is effected upon the suspension parameters. Experiments study the effects of braking performance on bicycle riding safety has been performed .An experimental platform is employed mainly for measuring the forces including braking force, lateral force, front-wheel and rear-wheel load. The braking distance could also be estimated in this experiment. Cheng-Kuo Sung 宋震國 2002 學位論文 ; thesis 74 zh-TW |
