Next to an increase in the number of car users, comfort has become a major aspect by which car manufacturers can distinguish their products from their competitors. At today, the assessment of seating comfort is largely based on subjective measures. A disadvantage of such measures is that the relationship with design parameters is often unclear. Furthermore, prototype development and testing are both time consuming and costly. In this respect, virtual testing tools represent promising solutions to support early automotive tests and, ultimately, reduce development times and associated costs. Moreover, virtual testing tools allow to investigate parameters that are hard to measure, such as the intervertebral disc pressure or the pressure distribution in the human soft tissues of the buttocks, and put them in relation with (dis)comfort and physical complaints.For prediction of seating comfort by virtual testing, in addition to a detailed seat model, a highly sophisticated model of the occupant and objective parameters are necessary.
