The purpose of this study was first to extract the anthropometric data of typical Korean male adults, based on the three‐dimensional anthropometric data measured through the Size Korea project. The data were then analyzed to identify the differences in the anthropometric characteristics between typical Koreans and 3D Korean mannequinmannequins generated by digital human models. Revision equations were then suggested to improve the inaccuracy of digital human models. Typical Korean adults subject to the 3D body scan data were selected by factor analysis with respect to the 5th, 50th, and 95th percentiles. Comparisons of anthropometric differences included the differences of the height and length variables in the vertical direction and the breadth, depth, and circumference variables in the horizontal direction. These comparisons demonstrated the differences in the anthropometric characteristics between typical Koreans and Korean mannequins based on differences in body shape and proportions between Korean and Western populations. Typical Koreans have shorter legs and longer torso than those of such mannequins generated from their own modeling algorithms, and the body shape of Koreans is more of an inverted triangular shape compared to the models. Although 3D digital human models are required to be modified to appropriately reflect the Asian body shape, modification of the modeling algoritms is not available to the public. The revision equations that convert the Korean modeling data of RAMSIS and Human in CATIA into typical Korean anthropometric data were instead suggested by regression analysis. It is expected that the proposed revision equations will help the designer evaluate design alternatives and improve the suitability of ergonomic evaluation for Korean customers. © 2012 Wiley Periodicals, Inc. 相似文献

Three dimensional models of shaft were completed on CATIA Part Design module with the Chinese national standard (GB) process structures such as chamfers, threads and tool withdrawal grooves, center holes, flat/woodruff/gib head taper keyseats, grinding undercuts, straight-sidedsplines, circlip slots and collars. The modeling steps are arranged in dialog menu interface by VB 6.0, the shaft creator, that permits users input geometric feature based parameters explicitly, and the standardized processdata are reorganized in Excel files that can be invoked correspondingly in the modeling procedure. It is aimed that this process may supply a simple way for shaft rapid modeling and comprehensive discipline for engineering students in their professional design activities. 相似文献
