This paper is contrary to the seat multi-dimensional problem basing on task space. Using double triangle steward parallel mechanism as the main structure of the seat suspension, according to the sensitive frequency range and the natural frequency of vehicle body, we optimize the design of the suspension system. Research shows that the optimized design of the double triangle Stewart parallel suspension seat suspension system to ensure vertical, pitch, roll three of the more important natural frequency both directions away from the vehicle's natural frequency, but also avoid the human body sensitive frequency range.

Suspension system is an important part of a vehicle which connects the road wheels and vehicle body. The major function of suspension is to isolate vehicle body from road disturbances. The design of suspension system is generally a compromise between many design requirements that aim to provide a comfortable ride and good vehicle handling. An optimization technique is used to choose the suspension parameters that meet these design requirements. In this present work a two degree of freedom quarter car vehicle vibration model is considered for optimization. Sprung mass acceleration and relative displacement of quarter car are considered as the measure of ride comfort and vehicle handling respectively. Golden section search optimization technique is used for single objective optimization of quarter car considering sprung mass acceleration as objective function and relative displacement as constraint. It is noticed that the accuracy level in getting the optimized value using this approach is comparatively high and reliable..
