The purpose of this paper is to analysis effects of shock absorbers on the dynamic behaviors of mountain-bikes subjected to forcing functions by using Solid work and ADAMS. In this paper, the structure of the bike consists of eight parts and two absorbers connected between the parts. The material properties, masses, and constrained conditions of parts are defined in ADAMS. Front and rear absorbers are described by using both the spring coefficient and the damping coefficient. In the analysis of simulation, the bike is subjected to periodic forcing functions can be written as the sum of harmonic functions using Fourier series. The corresponding Fourier coefficients are determined analytically and the Fourier series of the forcing function can be defined in ADAMS. Effects of spring coefficient and the damping coefficient of the front and rear absorbers on the position of center mass of the bike are examined.
