DIGITAL HUMAN BODY MODEL FOR SEAT COMFORT SIMULATION

摘要

Using the recent anthropometry of the North American population, human body models were developed for seat comfort simulation. The external geometry of the models was acquired from the three-dimensional whole body laser scan of recruited volunteers in a driving position. The selection criteria for volunteers with standard size and shape were derived from a statistical factor analysis of the SizeUSA database. As a practical application of the model in a design process, comfortable driving postures were constructed by adopting the cascade prediction model (CPM), which takes into account both interior package layout and the driver's anthropometry. The detail modeling process of finite element modeling and its validation results against volunteer measurements are introduced.
