Simple harmonic motion could be a special form of motion or oscillation motion wherever the restoring force is directly proportional to the displacement and acts within the direction opposite to it of displacement. This papers aim is to investigate about optimal damping constant of a quarter car shock absorber that is performed in the frequency domain. The optimum damping constant refers to the worth that minimizes the acceleration of all connected bodies characterizing a 2 degree of freedom system sketching a quarter car. The connected bodies are sprung and unsprung mass severally for quarter of chassis and tire, the last one maintain the contact with the lowest and it's connected with the sprung mass through a damper characterised by spring and fluid damper. Optimal damping constant resolve by imposing analytical conditions on the expression of acceleration of 2 masses. Afterwards, the variation of acceleration and position in function of frequency for the obtained value of damping constant is plotted numerically in two ways using Wolfram Mathematicia and MSC Adams Software.
