The body pressure distribution is an important index in evaluating seat static comfort. At present the interface pressure acquiring method of real person testing is unable to be used in the early stage of design for seat comfort evaluation. In this study a method for body pressure distribution simulation and comfort evaluation was realized which can be used in the early stage of design. The standard test-subject concept was proposed. According to the status and requirements of this study, and by sampling the Chinese anthropometry database the anthropometric dimensions of percentile-95 male, percentile-50 male and female, and percentile-5 female individuals were obtained. Based on these data the corresponding geometric and biomechanical models were established, which were used as the standard test-subjects of body pressure simulation. To meet the requirements of body pressure distribution simulation and comfort evaluation of automobile seats, the factors of the seat and human body in body pressure distribution were studied, as well as the methods for accurate body pressure distribution simulation. The interval-evaluation standard of body pressure and the head-neck comfort evaluation standard were established by small-scale experiments. The body pressure distribution simulation and comfort evaluation were implemented in the development of a specific SUV seat, which validated the effectiveness and accuracy of the above simulation methods and evaluation standards by tests. %K 标准被试， %K 座椅， %K 静态舒适性， %K 体压分布， %K 仿真评价
