Full foam type seat cushion for vehicle is made of such elements as panel, foam pad, and surface seat and each element individually effects on dynamic vibration comfort performance during riding. The most important requirement is to reduce resonance magnification of seat in the frequencies close to 6 Hz, which is the natural frequency of the human body's internal organs. Conventionally, the prediction of the resonance frequency characteristics of the seat cushion has been seldom done by calculation at design stage before evaluation of prototype test. This paper reports that it becomes possible to predict vibration property of seat cushion at design stage by solving vibration equation, which is obtained by replacing seat cushion structure with vibration system model having spring element and damping element equivalent to designed seat cushion and by making graph of resonance frequency characteristics using calculation program provided in this paper.
