The paper aim is the investigation of optimal damping constant ofa quarter car shock absorber that is performed in the frequency domain.The optimal damping constant refers to the value that minimizes theacceleration of all connected bodies characterizing a two degree of freedomsystem sketching a quarter car. The connected bodies are sprung andunsprung mass respectively for quarter of chassis and tire, the last onemaintain the contact with the ground and it is connected with the sprungmass through a shock absorber characterized by spring and fluid damper.Optimal damping constant was determined by imposing analyticalconditions on the expression of acceleration of two 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 usingWolfram Mathematica and MSC Adams software.
