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.
